1.-Bambiraptor: Half bird and half dinosaur The origin of his name can be found in Italian, because it is the combination of the Italian word bambino translated into our language means child and raptor due to his great kinship with the Velociraptor. As a rule, most dinosaurs that were carnivores were well below size compared to those that were herbivores. A clear example of this is the Bambiraptor, which with only 1 meter long and 30 centimeters was a carnivorous dinosaur. 2. Allosaurus: a ton of ferocity The genus Allosaurus was a group of Saurohisodic dinosaurs, theropods, allosaurs that lived during the Jurassic Period, about 155 million years ago and that shared its habitat with several gigantic sauropods. Its name comes from the Greek and literally means "strange lizard", mainly due to the protuberances that appear in its skull. 3.-Bruhathkayosaurus, the large-bodied lizard The Bruhathkayosaurus is a dinosaur sauropod titanosaur and could have reached about 220 tons. The existence of this dinosaur is quite questionable, but if it had existed it would have been undoubtedly one of the heaviest dinosaurs ever found. Besides having been one of the heaviest, it would also have been one of the largest, although its questionable existence is what precedes it. 4.-Carcharodontosaurus: The dangerous teeth The genus Carcharodontosaurus was a genus of dinosaur saurischians, theropods, and allies that lived on Earth about 112 million years ago, during the Cretaceous Period. It coincided in time with known species such as Spinosaurus, from which remains have been obtained indicating that there were battles between these two species. 5.-Dimorphodon: A mysterious flyer The genus Dimorphodon encompasses a series of aerial reptiles known as pterosaurs, so they are not dinosaurs, which lived on Earth about 200 million years ago, in the Early Jurassic. The meaning of the word Dimorphodon that gives name to the group is "teeth of two forms" since it owns two groups of teeth. This feature is very rare in pterosaurs and reptiles in general, since they have all teeth equal. This name was granted by Richard Owen in 1859. Two species have been found, an American one called D.wientrabu, and a European one found in the south of Great Britain and called D.macronyx, the English remains being the first to be found. 6.-Hippar: the little ancestor of horses Hipparion was a genus of prehistoric mammal that inhabited our planet during the Cenozoic and more specifically in what we know as the Neogene period (about 10 million years ago). It is classified within the group of the perisodáctilos mammals. This genre would have looked similar to a current horse. The only difference between the current horses and them is that they, the hipparions, would be somewhat smaller. 7.-Doedicurus: The giant armadillo This spectacular ancestral mammal belonged to the family of glyptodonts, as you will see this family has a close relationship with the current armadillos. The Doedicurus clavicaudatus and the Doedicurus patagonicus are the only species of the genus Doedicurus that have been found. The prehistoric animal that occupies the present article lived during the Cenozoic, was that it precedes the current one. Within the Cenozoic there are much more precise temporal subclassifications and the Doedicurus specifically pertains to the Quaternary Period. 8.-Dinosaur Zuniceratops We continue with our review of the ceratopsians and today we have to talk about the Zuniceratops, another dinosaur that stands out for its robust head and for being one of the first dinosaurs with horns over the eyes. Let's see what else is interesting about this dinosaur with horns. As for its physical characteristics, its height was about one meter, it was about 3 meters long and it weighed almost 250 kilos. Of course, the most remarkable aspect is undoubtedly its two horns on the eye sockets, since within paleontology has not yet found another older dinosaur that has them. 9.-Dinosaur Montanoceratops The genus Montanoceratops is a genus of ceratopsian ornithischian dinosaurs that lived at the end of the Late Cretaceous Period, and may be the last dinosaurs to disappear in the extinction of the Cretaceous. This dinosaur, which is also called "face with horns of Montana", is a genus that is classified within the Leptoceratopsidae family and that is only represented by one species, the Montanoceratops cerorhynchos. It lived during the Cretaceous era (about 65-71 million years ago) in what is now North America. Among its physical characteristics we can highlight its large head, the small horn that has in the nose and the "plate" that it has in the head. According to different studies, it is estimated that the males had that plaque larger than the females and that it was used to perform the courtship. Its height was about 2 meters and it weighed approximately 400 kilos. 10.-Deinosuchus: A crocodile to fear Cretaceous approximately 80 million years ago. Its name means "terrible crocodile", and reached 15 meters of lontigud and weigh more than 9 tons, which makes it one of the largest crocodiles ever on Earth. These dimensions are capable of leaving small the largest of the current crocodiles, and only surpassed in size by the Purusaurus. Deinosuchus lived in present-day North America, and it seems he may have shared territory with the Tyrannosaurus rex, which it seems he would not have feared and would have faced directly. Apart from the T.rex, this crocodile was able to hunt almost any thirsty dinosaur that approached a shore to drink a little and did not notice the Deinosuchus stalking from the depths.

Deinonicus

Species: Deinonychus Antirrhopus
His name means Terrible Claw. He lived during the Early Cretaceous period. This predator fed on animals and small dinosaurs. It measured three meters long and weighed up to 80 kilos. One of the most remarkable characteristics of this dinosaur is the claw of the second toe of its legs. With her he killed his prey. To walk, he only used his third and fourth fingers. This small predator hunted in a group. Fossils have been found in Montana and Wyoming, United States.

Species: Archaeopterix Lithographica
His name means Ancient Wing. This primitive bird lived in the Jurassic period. It was a carnivorous dinosaur. His diet probably included small reptiles, mammals and insects. It measured approximately 60 centimeters and weighed 500 grams. It is considered the first bird. It is one of the most important fossils, because it provides evidence that supports the theory that birds evolved from an ancestor that was a dinosaur. The fossil skeletons of this species show that they were not as good flyers as the current birds. To date, eight specimens have been found in southern Germany.

Ornitomimo

Species: Ornithomimus Velox
Its name means Quick Bird Impersonator. He lived during the late Cretaceous period. This species was omnivorous. It fed on plants, insects and even eggs of other dinosaurs. It measured three meters long and weighed up to 150 kilograms. It was assigned this name because of its great resemblance to modern birds, such as the ostrich. Their fossil remains have been found in Colorado and Montana, United States, and Alberta, Canada.

Velociraptor

Species: Velociraptor Mongoliensis
Its name means Rapid Hunter of Mongolia. He lived during the late Cretaceous period. It measured up to 1.8 meters in length and weighed 15 kilograms. It was carnivorous. It is believed that its favorite prey was Protoceratops. He was the size of a current wolf and probably hunted in a group, which allowed him to kill prey much larger than him. Like Deinonicus, it had a powerful claw on its legs, with which it mortally wounded its prey. Its fossils have been found in Mongolia and China.
.
Gallimimo

Species: Gallimimus Bullatus
Its name means Reptil Hen. He lived during the late Cretaceous period. It measured four meters and weighed a little more than four tons. He was omnivorous and his diet consisted of small animals, insects, eggs and plants that he obtained after casting the mud with his comb teeth. This nimble dinosaur walked on two slender legs. Probably ran as fast as the ostrich, which reaches a speed of up to 70 kilometers per hour. Fossil remains have been found in the Gobi Desert and Mongolia.

Alosaurus

Species: Allosaurus Fragilis
His name means Delicate Reptil Extraño. This carnivore lived in the late Jurassic period. It measured approximately 12 meters long and weighed up to two tons. It fed on small dinosaurs such as Camptosaurus and Stegosaurus, as well as lizards and mammals. It is characterized by the protuberances in front of each eye. To date, it is not known exactly what their function was. It is one of the dinosaurs that have more information, especially in regard to its anatomy, appearance and way of life. Fossil remains have been found in the western United States, Portugal and Australia.

Diplodocus

Species: Diplodocus Longus
Its name means Double Beam. He lived during the late Jurassic period. The diet of this herbivore may have included leaves and fruits of tall trees and shrubs, as well as ferns and equisetuses that grew at ground level. It measured up to 27 meters long and it is estimated that it weighed 20 tons. The teeth of this dinosaur were located in the front area of ​​the jaw. They were pencil-shaped and aligned in a similar way to the teeth of a comb. Various studies suggest that Diplodocus could not keep its neck up for a long time. The end of its tail was very thin, which allowed it to be used as a whip to defend itself from its predators. Fossil remains have been found in Utah, Colorado and Wyoming, United States.

Amargasaurus

Species: Amargasaurus Cazaui
Its name means Reptil de la Amarga, name of an Argentine province. He lived at the beginning of the Cretaceous period. It fed on plants, probably conifers, which dominated at that time. It measured up to 10 meters in length and weighed approximately five tons. He lived in herds, which migrated when food was scarce. It is believed that their thorns used to defend themselves or during courtship.

Tyrannosaurus

Species: Tyrannosaurus Rex
Its name means Reptile Tyrant. He lived during the late Cretaceous period. It measured 10 to 14 meters in length and weighed between four and seven tons. It was one of the fiercest carnivores. Some fossil bones of Edmontosaurus and Triceratops show marks of the teeth of this predator. The hands of Tyrannosaurus were so short that they did not serve to take the food to the snout. Fossils have been found in western North America. For almost a hundred years, it was considered the largest carnivore, but in South America and Africa, larger specimens have been discovered, such as Gigantosaurus.

Mamenquisaur

Species: Mamenchisaurus Hochuanensis
Its name means Lizard of Hochuan and Mamenchi. He lived during the late Jurassic period. It was herbivorous and fed on the foliage of trees. It measured 25 meters long and weighed 27 tons. So far a complete fossil skeleton has not been found, but a large part of it, which has allowed us to know what it was like. Apparently he traveled in packs, possibly when his food was scarce. Their fossil remains have been found in China.

Tecodontosaurus

Species: Thecodontosaurus Antiquus
Its name means Ancient Lizard with Small Teeth. He lived during the late Triassic period. It was approximately three meters long. He had four fingers on the hind legs and five on the front. It is the oldest prosauropod that is known. The prosauropods are the first large herbivorous dinosaurs. They were characterized by having a small head, relatively long neck and hind legs longer than the front ones. All had large fingernails and curved thumbs. The fossil remains of this species have been found in England

Pterodactylus is a genus of pterosaur, whose members are popularly known as pterodactyls. He was the first to be named and identified as a flying reptile. Their fossil remains have been found primarily in the Limestone of Solnhofen in Bavaria, Germany, dating from the late Jurassic period (early Titonian), between 150.8-148.5 million years ago, [2] although more fragmentary remains have been identified in other parts of Europe and in Africa. He was a carnivore and probably hunted fish and other small animals. Like all pterosaurs, the wings of Pterodactylus were formed by a membrane of muscle and skin that extended from its elongated fourth finger to its hind legs. This was maintained internally by collagen fibers and externally by keratinous edges.

Spinosaurus aegyptiacus

The Ankylosaurus dinosaur is a specimen of ankylosaurid that lived on Earth 60 million years ago, precisely in the Upper Cretaceous period, in North America.
Ankylosaurus means Armored Lizard, a name that is related to your skin, which is usually related to an armor. Only one species is known of this animal, the A. magniventris, which according to research survived until the extinction of the dinosaurs in the Tertiary Cretaceous. It is considered the most prominent and representative armored dinosaur.
This species was found in 1906 Barnum Brown, who gave it the name that distinguishes it today. That moment what was found was a skull, vertebrae, ribs and armor.

Bahariasaurus ingens
It is the smallest of the largest carnivores on Earth. Its name means "Reptile of the Baharia oasis", found in Africa and belonging to the Cretaceous period, where it lived 95 million years ago. It was a large predator that reached 11 or 12 meters in length but lighter than other large carnivores of that size and weighing 2.5 tons. At first it was thought that it was one of the last species of Carcharodontosaurus or of the first species of Tyrannosaurus, but finally it was included in a separate genus.

Tyrannosaurus
Species: Tyrannosaurus Rex
Its name means Reptile Tyrant. He lived during the late Cretaceous period. It measured 10 to 14 meters in length and weighed between four and seven tons. It was one of the fiercest carnivores. Some fossil bones of Edmontosaurus and Triceratops show marks of the teeth of this predator. The hands of Tyrannosaurus were so short that they did not serve to take the food to the snout. Fossils have been found in western North America. For almost a hundred years, it was considered the largest carnivore, but in South America and Africa, larger specimens have been discovered, such as Gigantosaurus.

Tarbosaurus bataar
is a genus of dinosaur that lived around 70 million years ago in Asia, specifically in the Cretaceous. Of this animal, also known as an alarming reptile for its translation from Greek into Spanish, a single species is known with certainty, the Tarbosaurus Bataar.
The first fossils of this specimen were found in Mongolia and China, being the year 1946 the collected in history for the development of an expedition to the Gobi Desert in Mongolia that compiled a skull and some vertebrae.
The first description of this animal was made in 1955 by Evgeny Maleev, who was helped by new skulls, carriers of valuable information. At first, from the fossil remains found it was thought that there were three species of Tarbosaurus, which eventually became the study of individuals of different ages.

Saurophaganax maximus
This "supreme among murderous lizards" is the oldest of the great carnivorous giants, which existed on earth more than 150 million years ago, in the famous Jurassic period, in what is now North America. The second of the list with 9-11 meters head to tail, 3.5 meters high and just over 3 tons of weight. It has created controversy of whether it belongs to a genus of its own or is part of the Allosaurus, because its size is far superior to the latter.

Mapusaurus roseae

Also from the Cretaceous period, this "land lizard" lived 95 million years ago in South America. Lesser than its close relative, the Giganotosaurus, its size was around 12 meters long and weighing 5 tons. Because 7 sets of fossils have been found in one place, it is thought that this hunter acted in groups, making it even more dangerous.

Dicraeosaurus
The investigations locate this species at the end of the Jurassic period. It was six meters high and weighing approximately 15 tons. The Dicraeosaurus or "hairpin reptile" contained a row of very peculiar spines on its back and an elongated tail, although it did not possess a long neck.

Mamenchisaurus
Perhaps the 25 meters long is not the most curious aspect of this species of dinosaurs, but of that figure, 15 meters belonged exclusively to his neck. The forelimbs of the Mamenchisaurus were much shorter than the later ones, and as regards its geographical distribution, it lived mainly in Asia.

ArqueopterixSpecies: Archaeopterix LithographicaHis name means Ancient Wing. This primitive bird lived in the Jurassic period. It was a carnivorous dinosaur. His diet probably included small reptiles, mammals and insects. It measured approximately 60 centimeters and weighed 500 grams. It is considered the first bird. It is one of the most important fossils, because it provides evidence that supports the theory that birds evolved from an ancestor that was a dinosaur. The fossil skeletons of this species show that they were not as good flyers as the current birds. To date, eight specimens have been found in southern Germany.

Ornitomimo
Species: Ornithomimus Velox
Its name means Quick Bird Impersonator. He lived during the late Cretaceous period. This species was omnivorous. It fed on plants, insects and even eggs of other dinosaurs. It measured three meters long and weighed up to 150 kilograms. It was assigned this name because of its great resemblance to modern birds, such as the ostrich. Their fossil remains have been found in Colorado and Montana, United States, and Alberta, Canada.

Velociraptor
Species: Velociraptor Mongoliensis
Its name means Rapid Hunter of Mongolia. He lived during the late Cretaceous period. It measured up to 1.8 meters in length and weighed 15 kilograms. It was carnivorous. It is believed that its favorite prey was Protoceratops. He was the size of a current wolf and probably hunted in a group, which allowed him to kill prey much larger than him. Like Deinonicus, it had a powerful claw on its legs, with which it mortally wounded its prey. Its fossils have been found in Mongolia and China.

Gallimimo
Species: Gallimimus Bullatus
Its name means Reptil Hen. He lived during the late Cretaceous period. It measured four meters and weighed a little more than four tons. He was omnivorous and his diet consisted of small animals, insects, eggs and plants that he obtained after straining the mud with his comb teeth. This nimble dinosaur walked on two slender legs. Probably ran as fast as the ostrich, which reaches a speed of up to 70 kilometers per hour. Fossil remains have been found in the Gobi Desert and Mongolia.

Alosaurus
Species: Allosaurus Fragilis
His name means Delicate Reptil Extraño. This carnivore lived in the late Jurassic period. It measured approximately 12 meters long and weighed up to two tons. It fed on small dinosaurs such as Camptosaurus and Stegosaurus, as well as lizards and mammals. It is characterized by the protuberances in front of each eye. To date, it is not known exactly what their function was. It is one of the dinosaurs that have more information, especially in regard to its anatomy, appearance and way of life. Fossil remains have been found in the western United States, Portugal and Australia.

Diplodocus
Species: Diplodocus Longus
Its name means Double Beam. He lived during the late Jurassic period. The diet of this herbivore may have included leaves and fruits of tall trees and shrubs, as well as ferns and equisetuses that grew at ground level. It measured up to 27 meters long and it is estimated that it weighed 20 tons. The teeth of this dinosaur were located in the front area of ​​the jaw. They were pencil-shaped and aligned in a similar way to the teeth of a comb. Several studies suggest that Diplodocus could not keep its neck up for a long time. The end of its tail was very thin, which allowed it to be used as a whip to defend itself from its predators. Fossil remains have been found in Utah, Colorado and Wyoming, United States.

Tyrannosaurus
Species: Tyrannosaurus Rex
Its name means Reptile Tyrant. He lived during the late Cretaceous period. It measured 10 to 14 meters in length and weighed between four and seven tons. It was one of the fiercest carnivores. Some fossil bones of Edmontosaurus and Triceratops show marks of the teeth of this predator. The hands of Tyrannosaurus were so short that they did not serve to take the food to the snout. Fossils have been found in western North America. For almost a hundred years, it was considered the largest carnivore, but in South America and Africa, larger specimens have been discovered, such as Gigantosaurus.

Tecodontosaurus
Species: Thecodontosaurus Antiquus
Its name means Ancient Lizard with Small Teeth. He lived during the late Triassic period. It was approximately three meters long. He had four fingers on the hind legs and five on the front. It is the oldest prosauropod that is known. The prosauropods are the first large herbivorous dinosaurs. They were characterized by having a small head, relatively long neck and hind legs longer than the front ones. All had large fingernails and curved thumbs. The fossil remains of this species have been found in England.

Spinosaurus
Species: Spinosaurus Aegyptiacus
Its name means Spiny Reptile of Egypt. He lived during the Early Cretaceous period. The Spinosaurus was up to 15 meters long and weighed four tons. Perhaps the diet of this carnivore included fish and other dinosaurs. To date no remains of food have been found in any fossil. It is believed that its huge crest absorbed and dispersed the heat. This regulated his body temperature. Perhaps it was also useful for courtship. The fossils of this dinosaur have been found in Egypt, Tunisia and Morocco.

Tarbosaurus bataar
is a genus of dinosaur that lived around 70 million years ago in Asia, specifically in the Cretaceous. Of this animal, also known as an alarming reptile for its translation from Greek into Spanish, a single species is known with certainty, the Tarbosaurus Bataar.
The first fossils of this specimen were found in Mongolia and China, being the year 1946 the collected in history for the development of an expedition to the Gobi Desert in Mongolia that compiled a skull and some vertebrae.
The first description of this animal was made in 1955 by Evgeny Maleev, who was helped by new skulls, carriers of valuable information. At first, from the fossil remains found it was thought that there were three species of Tarbosaurus, which eventually became the study of individuals of different ages.

Tyrannosaurus Rex

The name comes from the Greek word Tyranno, whose translation can be understood as despotic or evil, and Saurus meaning "similar to a lizard". At the same time, the word of Latin origin "Rex" that accompanies the name, and whose meaning is precisely "King", comes to describe the qualities of arrogance, strength, size and dexterity of the most popular dinosaur of all time: the Tyrannosaurus Rex

Carcharodontosaurus saharicus
Carcharodontosaurus is the name that represents the genus of theropod dinosaurs carcarodontosaurids, which populated the Earth more than 93 million years ago, in the middle of the Cretaceous period.
Africa was the continent that Carcharodontosaurus inhabited along with Spinosaurus. The name of the dinosaur in question comes from the Greek καρχαρο which means "sharp" and οδοντο odonto "tooth" - name of a shark genus-; which was used for the Carcharodontosaurus to be identified as Reptil shark tooth.

Spinosaurus aegyptiacus
The Ankylosaurus dinosaur is a specimen of ankylosaurid that lived on Earth 60 million years ago, precisely in the Upper Cretaceous period, in North America.
Ankylosaurus means Armored Lizard, a name that is related to your skin, which is usually related to an armor. Only one species is known of this animal, the A. magniventris, which according to research survived until the extinction of the dinosaurs in the Tertiary Cretaceous. It is considered the most prominent and representative armored dinosaur.
This species was found in 1906 Barnum Brown, who gave it the name that distinguishes it today. That moment what was found was a skull, vertebrae, ribs and armor.

Apatosaurus
Its main features were its head of small dimensions, a thick neck, and a flat face that was about 55 centimeters long overall. Apatosaurus could reach 30 tons of weight, and it was an extremely corpulent diplodocus, much heavier than Diplodocus.

Dicraeosaurus
The investigations locate this species at the end of the Jurassic period. It was six meters high and weighing approximately 15 tons. The Dicraeosaurus or "hairpin reptile" contained a row of very peculiar spines on its back and an elongated tail, although it did not possess a long neck.

Mamenchisaurus
Perhaps the 25 meters long is not the most curious aspect of this species of dinosaurs, but of that figure, 15 meters belonged exclusively to his neck. The forelimbs of the Mamenchisaurus were much shorter than the later ones, and as regards its geographical distribution, it lived mainly in Asia.

Carcharodontosaurus saharicus
The Carcharodontosaurus was a dinosaur that lived with other of the most fearsome reptiles of its time, in the area of Africa. It was a huge reptile almost thirteen meters long and had some shark teeth. Although the experts do not know how much it actually measured and weigh, its up to five meters high and 15 tons of weight make it the third largest land carnivore in all history. In addition, it was an animal much faster than the Rex because it could exceed thirty kilometers per hour and its teeth and claws were capable of tearing its prey while holding them held.

Acrocanthosaurus atokensis
This species of dinosaur inhabited the earth during the Lower Cretaceous and its habitat was what is now known as the United States. This species had a backbone of thorns and that is why its name means "lizard with high spines". On this back were joined very strong muscles in the form of a hump very similar to those that currently have bison. The largest specimen of this species reached almost twelve meters and weighed about five and a half tons in weight.

Askeptosaurus
Askeptosaurus inhabited European waters during the Triassic period, approximately 220 million years ago. It was part of a family of diapsid reptiles, called Thalattosaurus.
The main findings of fossils have been produced in European countries such as Italy and Switzerland, although this does not rule out that in addition to Europe they have entered other waters.
The Askeptosaurus was very similar in its habits and routines to the aquatic reptiles of today. Mostly they were submerged in the water and ventured into the land only to lay their eggs.

Therodite  Giant species of flying dinosaurs such as the terdactyls were similar in size to modern aircraft.In the past and based on the fossils discovered, paleontologists had estimated that the largest size of a terosaur was 10 meters, and was the largest animal to fly. However, new findings in Israel and Mexico now suggest that these specimens of dinosaurs were twice as large, comparable with modern aircraft.The scientist David Martill explained in the Daily Telegraph that: "these dinosaurs were the size of a small airplane. Although we only have fragments of fossils, they are huge. In addition, methods of tissue preservation suggest that these dinosaurs had very sophisticated structures. "The last known thermae was that of Quetzalcoatlus, discovered by the scientist Douglas Lawson in the Big Bend National Park of Texas, in the 1970s.The terosaurs, which flew with great ease and even walked closing their wings like bats, lived in the Triassic period with the oldest species of dinosaurs, 220 million years ago.These animals belong to the group of reptiles known as archosaurs, which include crocodiles, dinosaurs and birds.

1.-  Bahariasaurus ingens

It is the smallest of the largest carnivores on Earth. Its name means "Reptile of the Baharia oasis", found in Africa and belonging to the Cretaceous period, where it lived 95 million years ago. It was a large predator that reached 11 or 12 meters in length but lighter than other large carnivores of that size and weighing 2.5 tons. At first it was thought that it was one of the last species of Carcharodontosaurus or of the first species of Tyrannosaurus, but finally it was included in a separate genus.
2.- Saurophaganax maximus

This "supreme among murderous lizards" is the oldest of the great carnivorous giants, which existed on earth more than 150 million years ago, in the famous Jurassic period, in what is now North America. The second of the list with 9-11 meters head to tail, 3.5 meters high and just over 3 tons of weight. It has created controversy of whether it belongs to a genus of its own or is part of the Allosaurus, because its size is far superior to the latter.
3.- Epanterias amplexus

This "supreme among murderous lizards" is the oldest of the great carnivorous giants, which existed on earth more than 150 million years ago, in the famous Jurassic period, in what is now North America.

It has created controversy of whether it belongs to a genus of its own or is part of the Allosaurus, because its size is far superior to the latter.
4.- Mapusaurus roseae

Also from the Cretaceous period, this "land lizard" lived 95 million years ago in South America. Lesser than its close relative, the Giganotosaurus, its size was around 12 meters long and weighing 5 tons. Because 7 sets of fossils have been found in one place, it is thought that this hunter acted in groups, making it even more dangerous.
5. Tarbosaurus bataar

He inhabited the Earth 70 million years ago, in what is now Asia. It is so similar to Tyrannosaurus that some authors consider it the Asian subspecies of the famous American dinosaur. Its size and weight also resembled that of Tyrannosaurus (10-12 meters long, more than 4 meters high and between 6 and 7 tons). Its body structure was similar to that of the great dinosaurs, with strong and large hind legs that served as a point of support between the body and the long and heavy tail that balanced it. Their "hands" are the smallest proportionally to the rest of the body, with only two fingers
6.-
Acrocanthosaurus atokensis

Slightly older than the members of this list, this species of lower Cretaceous (120-112 million years) that has been found in the US is famous for its spiny back, hence its name means "lizard with high spines" to which strong muscles in the shape of a hump were tied like that of the current bison, very different from the "dorsal sail" of the Spinosaurians. The largest individual that has been found reached almost a dozen meters in length, as well as 5.5 tons in weight.
7.-
Carcharodontosaurus saharicus
This "reptile tooth of shark" coexisted with other of the largest terrestrial predators, 100-93 million years ago in Africa, sharing territory with the Spinosaurus. Its 12-13 meters in length, 3.5-5 meters in height and between 6 and 15 tons in weight (the experts do not agree with the estimates) make it the third largest terrestrial carnivores in history. To this we had to add that it was faster than the Tyrannosaurus reaching over 30 km / h in the race. Their teeth, similar to those of the sharks (hence their name), tore their prey until they died bled, using their sharp claws to hold them while it happened.
8.-
Tyrannosaurus rex

The "king of tyrant lizards" and we have always believed the largest and most ferocious terrestrial predator, has been relegated to a fourth place in terms of size. Quite younger than his older brothers, his reign is set between 67.7 and 65 million years ago, the rank of the Upper Cretaceous. Both its size, about 12.3 meters in length, 4 in height and a weight of 6 to 18 tons, and its jaw, which thanks to its powerful muscles could exert a force of 3,000 kg and go through a steel drum made of this dinosaur the most feared of his time. However, it had its defects, and that is that an adult human can easily escape from it, because although its legs are very strong, they do not allow it to run at more than 20-25 km / h. We must also bear in mind that his brain could double in size to that of other carnivores of its dimensions or even greater, giving him an intelligence that made him more dangerous when hunting and strategizing.

9.-


Giganotosaurus carolinii

With a range on the temporal scale similar to Spinosaurus, 100-97 million years ago, it left skeletal remains in South America. Known as "giant southern wind reptile", it is the second largest bipedal and carnivorous animal that the Earth has known with a size between 12.2 and 13 meters and an estimated weight of 6.5 to 13.8 tons. It is an animal with strong legs, but slow, reason why it is believed that it hunted in ambushes or not fast prey. In addition, it is the theropod with the largest skull in reference to its body, with laterally flattened and serrated teeth, ideal for tearing flesh.
10.-
Spinosaurus aegyptiacus

And as the undisputed king of the largest land predators that have ever existed, we find this "thorn lizard". This gigantic being lived on our planet 112-97 million years ago (Cretaceous period) and discovered in Egypt, ousted the T-rex as far as large carnivores are concerned. Its size is estimated between 15 and 18 meters in length, with a weight that is not yet well established, since according to which expert mentions, it goes from 9 tons to 20. This dinosaur was famous for its famous dorsal sail, formed because the vertebrae of his back had very long spines. It is believed that this ridge had a thermoregulation function, being a cold-blooded animal, like the current lizards. It is thought, by the fossils of marine beings that have appeared with remains of stomach acid from Spinosaurus, that this great predator not only exploited the terrestrial environment, but also took advantage of its long nose to fish in fresh water.

The dinosaurs were huge terrestrial reptiles that inhabited the earth for more than 150 million years, in the era known as Mesozoic. They were four-legged oviparous and had straight limbs, unlike the crocodiles and lizards that have bowed out.

Everything that is known about these fascinating creatures has been possible thanks to the fossils that have been found throughout the world. Over the years, quite real simulations have been made from these skeletons, which have provided a clearer idea to scientists and paleontologists of how these animals were.

1.-ALOSAURIO (ALLOSAURUS FRAGILIS)These carnivorous dinosaurs were characterized by the protuberances they displayed in front of each eye. They fed on other smaller dinosaurs such as Camptosaurus and Stegosaurus, as well as lizards and mammals.
2.-AMARGASAURIO (AMARGASAURUS CAZAUI)These herbivorous dinosaurs fed on plants, especially the conifers that were the most abundant in the Cretaceous. They could measure up to 10 meters in length and weigh up to five tons. In the body they had thorns that served them as defense and during courtship.

3.-ARQUEOPTERIX (ARCHAEOPTERIX LITHOGRAPHICA)This primitive bird dating from the Jurassic period is considered the first bird. The discovery of his fossil was definitive as evidence to support the existing theory that birds had evolved from a dinosaur. It was carnivorous and included in its diet small reptiles, insects and mammals.

4.-BRAQUIOSAURIO (BRACHIOSAURUS BRANCAI)This herbivore that could measure up to 28 meters and weigh up to 50 tons, was adapted to feed on the tallest trees. It is the only dinosaur known with its front legs longer than the hind legs.
español

5.-PAQUICEFALOSAURIO (PACHYCEPHALOSAURUS WYOMINGENSIS)Among the characteristics that stand out of this herbivore are the huge bony vault in his head, which could measure up to 25 centimeters thick and the numerous prominences that surrounded it. This structure is believed to have fulfilled some function in the mating rituals.

6.-PROTOCERATOPS (PROTOCERATOPS ANDREWSI)This species that also fed on plants lived in the late Cretaceous period. It was only two meters tall and weighed 177 kilos. In the skull they had what appeared to be horns, but really they were bony buttons on the tip of the nose and cheeks

7.-STEGOSAURIO (STEGOSAURUS ARMATU)

This other herbivorous dinosaur had plaques on the body that could measure up to one meter in height. The larger plates were placed on his hip and it is believed that they were used to regulate body temperature.

8.-LAMBEOSAURIO (LAMBEOSAURUS LAMBEI)

These dinosaurs had a very characteristic denture that allowed them to crush the harder plants. It was several rows of teeth piled on top of each other, which could reach 700 teeth.

9.-ANCHILOSAURIUM (ANKYLOSAURUS)The body of this herbivorous dinosaur was completely protected by spines and bone plates. The tail was also topped with a heavy mallet of bone, which they used to defend themselves against their attackers.

10.-APATOSAURIO (APATOSAURUS AJAX)This is another species of large herbivorous dinosaurs. In the initial recognition of their fossils there were some confusions and they were identified as two different species, so it is also possible that they refer to it as Brontosaurus.

1.     Troodon: The Troodon is a very interesting dinosaur whose name comes from the Greek and means tooth that hurts. There is only a single species lived in North America during the Campanian approximately 70 million years ago. He was one of the first dinosaurs that were discovered in North America in 1855. The Troodon had a neck relatively long and a jaw with teeth very sharp and small, her arms had 3 fingers with claws and powerful legs that made them excellent runners. I could measure approximately 2 meters high, one meter long and up to 50 kilos in weight. Their limbs were long and thin, so thought it was light and couldn't move very quickly, a special feature was that its upper limbs may have been bent like the of a bird.

2.     Gallimimus: The gallimimus was a bipedal omnivore dinosaur that lived in the Cretaceous period, about 70 million years ago. It had large eyes, had a long and flat, without teeth, beak on his small head. It had a long, flexible neck, and three fingers on each hand with sharp claws. The gallimimus is often compared with the current ostriches; especially in your legs long and thin, like a bird, and it is likely that the dinosaur was a runner fast, maybe faster dinosaur. The gallimimus lived during the Cretaceous period, 75 - 65000000 years ago.

3.     Abrictosaurus: The Abrictosaurus was an animal of small size that was found in the current South Africa, and due to different paleontological studies at that time the climate was similar to the present as to which there was a wet season and other dry, and that could make great migrations in search of food as do currently wildebeests.

4.     Mei: Mei genus consists of only one species, Mei long, which was a sort of dinosaur saurisquio theropod troodontido who lived approximately 135 million ago, in the Cretaceous, in the territories currently occupied by China (Asia). The name Mei means "deep sleep" and is known as "the dinosaur sleeping like hens" since the remains found were in position sleeping like a hen, very well preserved to be a small species of theropod remains from the Cretaceous.

5.     Dimorphodon: Period: the Dimorphodon lived during the Middle Jurassic period, years 175 - 160 000 000 fossil locations: Dimorphodon fossils have been discovered in some parts of Europe and America order: Pterosauria meaning of the name: teeth in two Location forms: Europe and America approximate magnitude: 4 feet (1, 22metros) approximate weight: 4 pounds diet: Carnivore

6.     Microraptor:The Microraptor was a flying dinosaur and has a resemblance to the current birds. This animal lived in heaven with wings that had in its four limbs. Would you like to know more about it? Let's see the basic information about our friend. How tall are long? -This flying dinosaur would have a length between 42 up to 83 cm. What is your height? -The average height of this exemplary era of approximately 30 centimetres. What is your weight? -The weight of this dinosaur bird would have hovered kg. When did he live? -This dinosaur would have inhabited our planet for the first time 131 million years ago until about 120 million years ago.

7.     Sarcosaurus: The extinct specimen turned out to actually be a theropod celofisido, which dwelt on Earth during the period that the scientists identified under the heading of Jurassic, this is to say that it developed its existence makes approximately 200 million years. Its name it was provided due to a great quality focused on food, i.e., the eating meat, so that this name means "lizard eating meat". Name: Sarcosaurus diet: carnivorousPeso: 120 kilogramos

8.     Avimimus: The genus Avimimus is represented by a single species belonging to the Group of saurischian dinosaurs theropods avimimidos. This group inhabited our planet in the Cretaceous period, makes approximately 70 million years ago, the territory currently known as Asia. The first official description of this prehistoric animal dates from the year 1981 and was performed by Dr. Sergi Kurzanov. The Avimimus name comes from latin and literally means "bird mimic", since their physiognomy is reminiscent of a current ave, without neglecting the characteristics of a dinosaur, Name: Avimimus diet: herbivorous weight: 20 kg period: Late Cretaceous found in: Asia

9.     Quetzalcoatlus: The Quetzalcoatlus was a genus of flying reptiles that lived on Earth during the Cretaceous period (specifically makes about 68 million years ago). It is classified within the Group of reptiles pterosaurs pterodactiloideos. This genre would have cohabited with the dinosaurs, but he is not considered one of them. Its appearance would have been compared to the feathered snake. Name: Quetzalcoatlus diet: carnivorous weight: 150 kg period: Cretaceous found in: Texas

10.   Giganotosaurus: Giganotosaurus carolinii is the only species that has been discovered in the genus Gigatonosaurus. It is a genus of theropod dinosaur which generated much controversy regarding its size and was even the cause of several scientific debates about maximum sizes which could reach this type of dinosaurs. Certainly what is clear is that it was one of the top predators of their habitat. But so that no doubts remain you what we will do in this post we present you in detail to this giant predator of the Cretaceous. Name: Giganotosaurus diet: carnivorous weight: 4 - 15 tons period: Cretaceous found in: Patagonia

Dinosaurs known as Saurischians emerged in the Triassic period about 228 million years ago and diversified during the Jurassic and Cretaceous periods. They are distinguished by having a hip similar to that of lizards, with the pubic bone facing forward.

All non-bird Saurischians became extinct in the Cretaceous, but Avian Saurischians are considered the ancestors of modern birds.

The Saurischians were divided into carnivorous dinosaurs and giant herbivores. Some of the species that were within this suborder are the following.

1 .-ALOSAURIO (ALLOSAURUS FRAGILIS)

These carnivorous dinosaurs were characterized by the protuberances they displayed in front of each eye. They fed on other smaller dinosaurs such as Camptosaurus and Stegosaurus, as well as lizards and mammals.
2.-AMARGASAURIO (AMARGASAURUS CAZAUI)

These herbivorous dinosaurs fed on plants, especially the conifers that were the most abundant in the Cretaceous. They could measure up to 10 meters in length and weigh up to five tons. In the body they had thorns that served them as defense and during courtship.

3.-ARQUEOPTERIX (ARCHAEOPTERIX LITHOGRAPHICA)

This primitive bird dating from the Jurassic period is considered the first bird. The discovery of his fossil was definitive as evidence to support the existing theory that birds had evolved from a dinosaur. It was carnivorous and included in its diet small reptiles, insects and mammals.

4.-BRAQUIOSAURIO (BRACHIOSAURUS BRANCAI)This herbivore that could measure up to 28 meters and weigh up to 50 tons, was adapted to feed on the tallest trees. It is the only dinosaur known with its front legs longer than the hind legs.

5.-DEINONICUS (DEINONYCHUS ANTIRRHOPUS)This predator whose name means terrible claw, fed on animals and other small dinosaurs. Its most deadly tool was the claw of the second toe of its legs, with which it killed its prey. Only used to walk the third and fourth fingers.

6.-DIPLODOCUS (DIPLODOCUS LONGUS)Dinosaur species Another herbivorous species that fed on leaves and fruits of tall trees, as well as ferns and horsetails that were at ground level. He had a very thin tail that served him as a whip to protect himself from his attackers.

7.-SPINOSAUR (SPINOSAURUS AEGYPTIACUS)The fossils of these dinosaurs have been found in Egypt, Tunisia and Morocco. It is known that it was a carnivore, but there is no certainty as to which animals were included in its diet because no remains of food have been found in any fossil. It had a huge ridge that is believed to absorb and disperse heat.

8.-GALLIMIMO (GALLIMIMUS BULLATUS)This omnivorous dinosaur, known as the chicken reptile, was very agile and walked on two thin legs. With an approximate height of four meters and a weight of around four tons, he obtained his food after casting the mud with his comb-like teeth.

9.-MAMENQUISAURIO (MAMENCHISAURUS HOCHUANENSIS)Of this herbivorous species it has not been possible to find a complete fossil skeleton, but parts of it. Apparently he traveled in packs, especially when food was scarce in the area.

10.-ORNITHOMIMO (ORNITHOMIMUS VELOX)

This omnivorous species fed on plants, insects and eggs of other types of dinosaurs. Its name responds to its great resemblance to some modern birds such as the ostrich. It measured about three meters long and could weigh up to 150 kg.

Arqueopterix

Species: Archaeopterix Lithographica
His name means Ancient Wing. This primitive bird lived in the Jurassic period. It was a carnivorous dinosaur. His diet probably included small reptiles, mammals and insects. It measured approximately 60 centimeters and weighed 500 grams. It is considered the first bird. It is one of the most important fossils, because it provides evidence that supports the theory that birds evolved from an ancestor that was a dinosaur. The fossil skeletons of this species show that they were not as good flyers as the current birds. To date, eight specimens have been found in southern Germany.

Ornitomimo

Species: Ornithomimus Velox
Its name means Quick Bird Impersonator. He lived during the late Cretaceous period. This species was omnivorous. It fed on plants, insects and even eggs of other dinosaurs. It measured three meters long and weighed up to 150 kilograms. It was assigned this name because of its great resemblance to modern birds, such as the ostrich. Their fossil remains have been found in Colorado and Montana, United States, and Alberta, Canada.

Velociraptor

Species: Velociraptor Mongoliensis
Its name means Rapid Hunter of Mongolia. He lived during the late Cretaceous period. It measured up to 1.8 meters in length and weighed 15 kilograms. It was carnivorous. It is believed that its favorite prey was Protoceratops. He was the size of a current wolf and probably hunted in a group, which allowed him to kill prey much larger than him. Like Deinonicus, it had a powerful claw on its legs, with which it mortally wounded its prey. Its fossils have been found in Mongolia and China.

Gallimimo

Species: Gallimimus Bullatus
Its name means Reptil Hen. He lived during the late Cretaceous period. It measured four meters and weighed a little more than four tons. He was omnivorous and his diet consisted of small animals, insects, eggs and plants that he obtained after casting the mud with his comb teeth. This nimble dinosaur walked on two slender legs. Probably ran as fast as the ostrich, which reaches a speed of up to 70 kilometers per hour. Fossil remains have been found in the Gobi Desert and Mongolia.

Alosaurus

Species: Allosaurus Fragilis
His name means Delicate Reptil Extraño. This carnivore lived in the late Jurassic period. It measured approximately 12 meters long and weighed up to two tons. It fed on small dinosaurs such as Camptosaurus and Stegosaurus, as well as lizards and mammals. It is characterized by the protuberances in front of each eye. To date, it is not known exactly what their function was. It is one of the dinosaurs that have more information, especially in regard to its anatomy, appearance and way of life. Fossil remains have been found in the western United States, Portugal and Australia.

Diplodocus

Species: Diplodocus Longus
Its name means Double Beam. He lived during the late Jurassic period. The diet of this herbivore may have included leaves and fruits of tall trees and shrubs, as well as ferns and equisetuses that grew at ground level. It measured up to 27 meters long and it is estimated that it weighed 20 tons. The teeth of this dinosaur were located in the front area of ​​the jaw. They were pencil-shaped and aligned in a similar way to the teeth of a comb. Various studies suggest that Diplodocus could not keep its neck up for a long time. The end of its tail was very thin, which allowed it to be used as a whip to defend itself from its predators. Fossil remains have been found in Utah, Colorado and Wyoming, United States.

Amargasaurus

Species: Amargasaurus Cazaui
Its name means Reptil de la Amarga, name of an Argentine province. He lived at the beginning of the Cretaceous period. It fed on plants, probably conifers, which dominated at that time. It measured up to 10 meters in length and weighed approximately five tons. He lived in herds, which migrated when food was scarce. It is believed that their thorns were used to defend themselves or during courtship.

Tyrannosaurus

Species: Tyrannosaurus Rex
Its name means Reptile Tyrant. He lived during the late Cretaceous period. It measured 10 to 14 meters in length and weighed between four and seven tons. It was one of the fiercest carnivores. Some fossil bones of Edmontosaurus and Triceratops show marks of the teeth of this predator. The hands of Tyrannosaurus were so short that they did not serve to take the food to the snout. Fossils have been found in western North America. For almost a hundred years, it was considered the largest carnivore, but in South America and Africa, larger specimens have been discovered, such as Gigantosaurus.

Mamenquisaur

Species: Mamenchisaurus Hochuanensis
Its name means Lizard of Hochuan and Mamenchi. He lived during the late Jurassic period. It was herbivorous and fed on the foliage of trees. It measured 25 meters long and weighed 27 tons. So far a complete fossil skeleton has not been found, but a large part of it, which has allowed us to know what it was like. Apparently he traveled in packs, possibly when his food was scarce. Their fossil remains have been found in China.

Tecodontosaurus

Species: Thecodontosaurus Antiquus
Its name means Ancient Lizard with Small Teeth. He lived during the late Triassic period. It was approximately three meters long. He had four fingers on the hind legs and five on the front. It is the oldest prosauropod that is known. The prosauropods are the first large herbivorous dinosaurs. They were characterized by having a small head, relatively long neck and hind legs longer than the front ones. All had large fingernails and curved thumbs. The fossil remains of this species have been found in England.

Extinction of dinosaurs
The discovery that birds are a type of dinosaur showed that in general dinosaurs are not, in fact, extinct as is commonly said. [143] However, all non-avian dinosaurs, as well as many groups of birds had suddenly they became extinct about 66 million years ago. It has been suggested that because small mammals, squamatas and birds occupied the ecological niches suitable for their small body size, non-avian dinosaurs never evolved a diverse fauna of small-bodied species, which led to their fall, when they were seen affected by terrestrial large-body tetrapods, as a consequence of the mass extinction event. [144] Many other groups of animals also became extinct at this time, including ammonites (nautilus-like mollusks), mosasaurs, plesiosaurs, pterosaurs, and many groups of mammals. [9] Significantly, the insects did not suffer any appreciable loss in their population, which left food available for other survivors. This massive extinction is known as the Cretaceous-Paleogene mass extinction. The nature of the event that caused this mass extinction has been widely studied since the 1970s; In the 21st century, several related theories have the support of paleontologists. Although the consensus is that an impact event was the main cause of the extinction of dinosaurs, some scientists cite other possible causes, or support the idea that a confluence of several factors was responsible for the sudden disappearance of dinosaurs from the fossil record .

At the height of the Mesozoic, there were no polar ice caps, and the sea level was between 100 and 250 meters higher than at present. The temperature of the planet was also much more uniform, with a difference of only 25 ° C (45 ° F) between polar and equatorial temperatures. On average, the atmospheric temperatures were also much warmer; the poles, for example, were 50 ° C (90 ° F) warmer than today.

The atmospheric composition during the Mesozoic was also very different. Carbon dioxide levels were up to twelve times higher than today, and oxygen represented between 32-25% of the atmosphere, compared to 21% today. However, by the end of the Cretaceous, the environment was changing dramatically. Volcanic activity was reduced, causing a cooling trend as atmospheric carbon dioxide levels dropped. Oxygen levels in the atmosphere also began to fluctuate and ended up falling considerably. Some scientists believe that climate change, along with lower oxygen levels, could have directly caused the disappearance of many species. If the dinosaurs had respiratory systems similar to those typical of modern birds, it could have been particularly difficult for them to adapt to lower respiratory performance, given the enormous amount of oxygen their bodies needed.

Pterodactylus is a genus of pterosaur, whose members are popularly known as pterodactyls. He was the first to be named and identified as a flying reptile. Their fossil remains have been found primarily in the Limestone of Solnhofen in Bavaria, Germany, dating from the late Jurassic period (early Titonian), between 150.8-148.5 million years ago, [2] although more fragmentary remains have been identified in other parts of Europe and in Africa. He was a carnivore and probably hunted fish and other small animals. Like all pterosaurs, the wings of Pterodactylus were formed by a membrane of muscle and skin that extended from its elongated fourth finger to its hind legs. This was maintained internally by collagen fibers and externally by keratinous edges.

The name of the Stegosaurus comes from the Greek and means lizard with roof or roof, this because it had plates and thorns in the part of the tail and the back that makes them a very special dinosaur and recognized by many.
The Stegosaurus lived in North America almost at the end of the Jurassic period, 150 million years ago, in the Kimeridgian and Titonian periods.
The main clue we have about their diet is that their heads were down, this suggests that they could have been browsing, feeding on leaves, plants and branches that grew near the ground, hence their beak was of great help to start these branches or herbs.
Without a doubt, its plates and spines or spines, is what makes Stegosaurus special.

1.-Tyrannosaurus rex : The "king of the tyrant lizards" and who has always believed the greatest and most ferocious terrestrial predator, has been relegated to a fourth place in terms of size. Quite younger than his older brothers, his reign is set between 67.7 and 65 million years ago, the rank of the Upper Cretaceous. Both its size, about 12.3 meters in length, 4 in height and a weight of 6 to 18 tons, and its jaw, thanks to its powerful, could fly with a power of 3,000 kg and go through with a steel drum . dinosaur the most feared of his time. This dinosaur became extinct because of a parasite. This parasite, of the Trichomonas species, produces an infection in the back of the jaw that prevents swallowing.
2.-El Lusotitan: lived at the end of the Jurassic period, about 150 million years ago, his diet was composed mainly of plants, using his long neck to reach them regardless of the height of the trees, was between 25 and 27 meters long and 11 meters high, besides weighing around 30 tons, they were extinguished by the fall of the Chicxulub asteroid.
3.-Triceratops: He lived during the late Cretaceous period. This herbivore fed on hard, fiber-rich plants. It measured nine meters and weighed approximately six tons. It was the largest of the horned dinosaurs that lived at the end of the Cretaceous. His teeth and his curved beak, like that of a parrot, were not suitable for chewing the plants he ate, but for cutting. He became extinct in the impact of the asteroid, by hunger and darkness, which eliminated the plants.
4.-The Ornitholestes: inhabited the Earth during the Jurassic period, measuring about 2 meters in length, half of which corresponded to the length of its tail and about 80 centimeters in height, weighed approximately 13 kilos, based its diet or consumption on consumption. of meat, whose favorite habitat were places with lots of vegetation or lush forests, were extinguished by the fall of the Chicxulub asteroid.
5.-Lambeosaurio: He lived during the late Cretaceous period. It measured up to 15 meters long and it is estimated that it weighed seven tons. The jaws of this dinosaur were characterized by having several rows of teeth piled on top of each other, reaching up to 700 teeth. This type of denture is known as a dental battery. It was very useful to crush the hard plants from which it was fed.
6.-The genus Apatosaurus: inhabited the Earth during the Jurassic Period, came to measure with a not inconsiderable height of 4.5 meters and a length of 23 meters, could have ingested a set of stones often referred to as gastroliths, this phenomenon being the same that some birds of our day do, they were extinguished by the fall of the Chicxulub asteroid.

7.-The Baryonyx: lived during the Cretaceous Period, approximately 120 million years ago, it was fed on fish, it measured almost 10 meters in length, in terms of its height it is estimated that it did not reach more than 3 meters and in As for its weight, it has been suggested that it did not have more than 3 tons, nothing less,they were extinguished by the fall of the Chicxulub asteroid.
8.-Deinonicus: He lived during the Early Cretaceous period. This predator fed on animals and small dinosaurs. It measured three meters long and weighed up to 80 kilos. One of the most remarkable features of this dinosaur is the claw of the second toe of its legs. With her he killed his prey. To walk, he only used his third and fourth fingers. This small predator hunted in a group.They were extinguished by the fall of the Chicxulub asteroid.
9.-Allosaurus Fragilis:This carnivore lived in the late Jurassic period. It measures approximately 12 meters long and weighs up to two tons. It fed on small dinosaurs such as Camptosaurus and Stegosaurus, as well as lizards and mammals. It is characterized by protrusions in front of each eye.

The Sarcosaurus
It inhabited our planet during the period that scientists identify under the name of Jurassic, this means that it developed its existence about 200 million years ago.
His denomination was given to him due to a great quality focused on his feeding, that is to say, the one to eat meat, is for that reason that this denomination means "lizard that eats meat".
Name: Sarcosaurus

8. The genus Apatosaurus inhabited the Earth during the Jurassic Period, came to measure with a not inconsiderable height of 4.5 meters and a length of 23 meters, could have ingested a set of stones often referred to as gastroliths, this phenomenon being the same that some birds of our day do, they were extinguished by the fall of the Chicxulub asteroid.
9. The Troodon inhabited our planet during the Cretaceous period, estimated to have been about 2 meters long, 1 meter high and no less than about 25 to 50 kilograms in weight, fed with plants, were extinguished by the fall of the asteroid of Chicxulub.
10. Stygimoloch consisted of 3 meters long and 2 meters high, located within the paquicefalosáuridos marginocéfalos, which developed all its existence in a territory in America, was fed with plants, were extinguished by the fall of the asteroid of Chicxulub.

Arqueopterix
Species: Archaeopterix Lithographica
His name means Ancient Wing. This primitive bird lived in the Jurassic period. It was a carnivorous dinosaur. His diet probably included small reptiles, mammals and insects. It measured approximately 60 centimeters and weighed 500 grams. It is considered the first bird. It is one of the most important fossils, because it provides evidence that supports the theory that birds evolved from an ancestor that was a dinosaur. The fossil skeletons of this species show that they were not as good flyers as the current birds. To date, eight specimens have been found in southern Germany.

Ornitomimo
Species: Ornithomimus Velox
Its name means Quick Bird Impersonator. He lived during the late Cretaceous period. This species was omnivorous. They feed on plants, insects and even eggs of other dinosaurs. It measured three meters long and weighed up to 150 kilograms. This name is bequeathed by its great resemblance to modern birds, such as the ostrich. Their fossil remains have been found in Colorado and Montana, United States, and Alberta, Canada.

Velociraptor
Species: Velociraptor Mongoliensis
Its name means Rapid Hunter of Mongolia. He lived during the late Cretaceous period. It measured up to 1.8 meters in length and weighed 15 kilograms. It was carnivorous. It is believed that its favorite prey was Protoceratops. He was the size of a current wolf and probably hunted in a group, which allowed him to kill prey much larger than him. Like Deinonicus, it had a powerful claw on its legs, with which it mortally wounded its prey. Its fossils have been found in Mongolia and China.

Gallimimo
Species: Gallimimus Bullatus
Its name means Reptil Hen. He lived during the late Cretaceous period. It measured four meters and weighed a little more than four tons. He was omnivorous and his diet consisted of small animals, insects, eggs and plants that he obtained after straining the mud with his comb teeth. This nimble dinosaur walked on two slender legs. Probably ran as fast as the ostrich, which reaches a speed of up to 70 kilometers per hour. Fossil remains have been found in the Gobi Desert and Mongolia.

Alosaurus
Species: Allosaurus Fragilis
His name means Delicate Reptil Extraño. This carnivore lived in the late Jurassic period. It measured approximately 12 meters long and weighed up to two tons. It fed on small dinosaurs such as Camptosaurus and Stegosaurus, as well as lizards and mammals. It is characterized by the protuberances in front of each eye. To date, it is not known exactly what their function was. It is one of the dinosaurs that have more information, especially in regard to its anatomy, appearance and way of life. Fossil remains have been found in the western United States, Portugal and Australia.

Diplodocus
Species: Diplodocus Longus
Its name means Double Beam. He lived during the late Jurassic period. The diet of this herbivore may have included leaves and fruits of tall trees and shrubs, as well as ferns and equisetuses that grew at ground level. It measured up to 27 meters long and it is estimated that it weighed 20 tons. The teeth of this dinosaur were located in the front area of ​​the jaw. They were pencil-shaped and aligned in a similar way to the teeth of a comb. Several studies suggest that Diplodocus could not keep its neck up for a long time. The end of its tail was very thin, which allowed it to be used as a whip to defend itself from its predators. Fossil remains found in Utah, Colorado and Wyoming, United States

Amargasaurus
Species: Amargasaurus Cazaui
Its name means Reptil de la Amarga, name of an Argentine province. He lived at the beginning of the Cretaceous period. It fed on plants, probably conifers, which dominated at that time. It measured up to 10 meters in length and weighed approximately five tons. He lived in herds, which migrated when food was scarce. It is believed that their thorns used to defend themselves or during courtship.

Tyrannosaurus
Species: Tyrannosaurus Rex
Its name means Reptile Tyrant. He lived during the late Cretaceous period. It measured 10 to 14 meters in length and weighed between four and seven tons. It was one of the fiercest carnivores. Some fossil bones of Edmontosaurus and Triceratops show marks of the teeth of this predator. The hands of Tyrannosaurus were so short that they did not serve to take the food to the snout. Fossils have been found in western North America. For almost a hundred years, it was considered the largest carnivore, but in South America and Africa, larger specimens have been discovered, such as Gigantosaurus.

Mamenquisaur
Species: Mamenchisaurus Hochuanensis
Its name means Lizard of Hochuan and Mamenchi. He lived during the late Jurassic period. It was herbivorous and fed on the foliage of trees. It was 25 meters long and weighed 27 tons. So far a complete fossil skeleton has not been found, but a large part of it, which has allowed us to know what it was like. Apparently he traveled in packs, possibly when his food was scarce. Their fossil remains have been found in China.

Tecodontosaurus
Species: Thecodontosaurus Antiquus
Its name means Ancient Lizard with Small Teeth. He lived during the late Triassic period. It was approximately three meters long. He had four fingers on the hind legs and five on the front. It is the oldest prosauropod that is known. The prosauropods are the first large herbivorous dinosaurs. They were characterized by having a small head, relatively long neck and hind legs longer than the front ones. All had large fingernails and curved thumbs. The fossil remains of this species have been found in England.

10. Bahariasaurus ingens
It is the smallest of the largest carnivores on Earth. Its name means "Reptile of the Baharia oasis", found in Africa and belonging to the Cretaceous period, where it lived 95 million years ago. It was a large predator that reached 11 or 12 meters in length but lighter than other large carnivores of that size and weighing 2.5 tons. At first it was thought that it was one of the last species of Carcharodontosaurus or of the first species of Tyrannosaurus, but finally it was included in a separate genus.

9. Saurophaganax maximus
This "supreme among murderous lizards" is the oldest of the great carnivorous giants, which existed on earth more than 150 million years ago, in the famous Jurassic period, in what is now North America. The second of the list with 9-11 meters head to tail, 3.5 meters high and just over 3 tons of weight. It has created controversy of whether it belongs to a genus of its own or is part of the Allosaurus, because its size is far superior to the latter.

8. Electerias amplexus
One of the two great carnivores of the Jurassic (156-144 million years) North Americans. This dinosaur was thought to be a giant individual of the Allosaurus family, but the difference of several meters and more than a ton of weight makes this hypothesis discarded, since with its 12 meters in length and more than 4 tons of estimated weight , rivals the great predators known so far.

7. Mapusaurus roseae
Also from the Cretaceous period, this "land lizard" lived 95 million years ago in South America. Lesser than its close relative, the Giganotosaurus, its size was around 12 meters long and weighing 5 tons. Because 7 sets of fossils have been found in one place, it is thought that this hunter acted in groups, making it even more dangerous.

6. Acrocanthosaurus atokensis

Slightly older than the members of this list, this species of lower Cretaceous (120-112 million years) that has been found in the US is famous for its spiny back, hence its name means "lizard with high spines" to which strong muscles in the shape of a hump were tied like that of the current bison, very different from the "dorsal sail" of the Spinosaurians. The largest individual that has been found reached almost a dozen meters in length, as well as 5.5 tons in weight.

5. Tarbosaurus bataar
He inhabited the Earth 70 million years ago, in what is now Asia. It is so similar to Tyrannosaurus that some authors consider it the Asian subspecies of the famous American dinosaur. Its size and weight also resembled that of Tyrannosaurus (10-12 meters long, more than 4 meters high and between 6 and 7 tons). Its body structure was similar to that of the great dinosaurs, with strong and large hind legs that served as a point of support between the body and the long and heavy tail that balanced it. Their "hands" are the smallest proportionally to the rest of the body, with only two fingers

4. Tyrannosaurus rex
The "king of tyrant lizards" and we have always believed the largest and most ferocious terrestrial predator, has been relegated to a fourth place in terms of size. Quite younger than his older brothers, his reign is set between 67.7 and 65 million years ago, the rank of the Upper Cretaceous. Both its size, about 12.3 meters in length, 4 in height and a weight of 6 to 18 tons, and its jaw, which thanks to its powerful muscles could exert a force of 3,000 kg and go through a steel drum made of this dinosaur the most feared of his time. However, it had its defects, and that is that an adult human can easily escape from it, because although its legs are very strong, they do not allow it to run at more than 20-25 km / h. We must also bear in mind that his brain could double in size to that of other carnivores of its dimensions or even greater, giving him an intelligence that made him more dangerous when hunting and strategizing.

3. Carcharodontosaurus saharicus
This "reptile tooth of shark" coexisted with other of the largest terrestrial predators, 100-93 million years ago in Africa, sharing territory with the Spinosaurus. Its 12-13 meters in length, 3.5-5 meters in height and between 6 and 15 tons in weight (the experts do not agree with the estimates) make it the third largest terrestrial carnivores in history. To this we had to add that it was faster than the Tyrannosaurus reaching over 30 km / h in the race. Their teeth, similar to those of the sharks (hence their name), tore their prey until they died bled, using their sharp claws to hold them while it happened.

2. Giganotosaurus carolinii
With a range on the temporal scale similar to Spinosaurus, 100-97 million years ago, it left skeletal remains in South America. Known as "giant southern wind reptile", it is the second largest bipedal and carnivorous animal that the Earth has known with a size between 12.2 and 13 meters and an estimated weight of 6.5 to 13.8 tons. It is an animal with strong legs, but slow, reason why it is believed that it hunted in ambushes or not fast prey. In addition, it is the theropod with the largest skull in reference to its body, with laterally flattened and serrated teeth, ideal for tearing flesh.

1. Spinosaurus aegyptiacus.
And as the undisputed king of the largest land predators that have ever existed, we find this "thorn lizard". This gigantic being lived on our planet 112-97 million years ago (Cretaceous period) and discovered in Egypt, ousted the T-rex as far as large carnivores are concerned. Its size is estimated between 15 and 18 meters in length, with a weight that is not yet well established, since according to which expert mentions, it goes from 9 tons to 20. This dinosaur was famous for its famous dorsal sail, formed because the vertebrae of his back had very long spines. It is believed that this ridge had a thermoregulation function, being a cold-blooded animal, like the current lizards. It is thought, by the fossils of marine beings that have appeared with remains of stomach acid from Spinosaurus, that this great predator not only exploited the terrestrial environment, but also took advantage of its long nose to fish in fresh water.
