The Indominus Rex is a genetically modified, man-made, hybrid dinosaur in the Jurassic World series. Dr. Henry Wu created it in 2012 by combining the DNA of several theropod dinosaurs, including the Tyrannosaurus Rex and Velociraptor, with the DNA of modern animals like tree dart frogs, cuttlefish, and pit vipers. The Indominus Rex was intended to be the most intelligent, largest, and deadliest dinosaur, and its name means "untamable king" or "fierce". 

As a more primitive predatory dinosaur, Dilophosaurus didn't have forward facing eyes to give it stereo vision. It may have used scent as an integral part of its hunting technique. It had long and slender, rear-curving teeth in long jaws and strong front arms which would have been effective in grabbing prey. It was fast - probably with a top speed of about 30-mph. Footprints attributed to Dilophosaurus appear in groups, so it may have hunted in small packs. It shares the same overall body configuration as Coelophysis even though Dilophosaurus is currently classified as a member of a different group of theropods rather than Coelophysis and its relatives.^[4]

As a defensive creature, Ankylosaurus was one of nature's most perfect designs. It was almost impervious to being bitten from above and its long, strong tail muscles would have been able to swing its club with great force, however, the tail wasn't too flexible and could only swing 45 degrees in each direction.^[1]

There is very little fossil material from this dinosaur - it was apparently the last and largest of the family of armored dinosaurs. It walked fairly upright on all four legs, carrying its tail off the ground and it is theorized that it would drop to the ground when attacked to use its armor as a shield to cover its legs and underbelly.^[1]

The Scorpios rex (codenamed E750) was a hybrid dinosaur frozen and held captive in InGen’s secret tunnels until it escaped. It was also a major antagonist of Jurassic World: Camp Cretaceous, serving as an unseen antagonist of Season 1, the unseen final antagonist of Season 2, the main antagonist of Season 3, and a posthumous antagonist of Seasons 4 and 5. There were two known individuals: the first one created by Henry Wu, with the second one being asexually reproduced by the original.

While determining exactly which theropod genera was the largest, metrics for Giganotosaurus have consistently placed it as larger than an average Tyrannosaurus and comparable to the largest known specimens of Tyrannosaurus. More specimens of the Giganotosaurus are required to give a clearer picture of size, as all species will exist within a spectrum of sizes. For now, it is safe to consider the likes of Giganotosaurus, Spinosaurus, and Tyrannosaurus as comparable to one another in terms of size (though Spinosaurus is technically the longer animal, it is comparable in weight to Tyrannosaurus and Giganotosaurus due to its more slender build in real life).

When Giganotosaurus was alive, the most common herbivores found in South America were the titanosaur sauropods such as Argentinosaurus, Dreadnoughtus, and Andesaurus, respectively. While a single Giganotosaurus was capable of killing a young titanosaur or a large ornithopod, it would take many Giganotosaurus to bring down a giant adult sauropod. Originally, there was no evidence that Giganotosaurus hunted in groups, but recent findings from slightly younger rocks shows that their sister taxon (closest relative) Mapusaurus may have formed coalitions similar to crocodiles or perhaps even family groups given the high size variation and age differences between individuals. While not known if this was true pack living behavior, these coalitions of 6 or more individuals would probably have been capable of coordinating attacks on targets of opportunity such as a large sauropod.

Its most distinctive feature was the huge sail on its back. This sail was comprised of spines that extended from the top of the backbones of all dinosaurs and vertebrates. The spines of Spinosaurus were tremendous, the longest one found measured over 1.7 meters (5 feet) tall. The sail might have been used to attract a mate, making it look bigger to other predators it shares with, or speculatively act as a dorsal fin as it moves through the water.^[1]

Similar to its relatives within the spinosauridae, it had large, powerful arms and enormous, hook like claws for grabbing prey, much like modern bears do today.

Discovered by German paleontologist Ernst Stromer in 1912, the first Spinosaurus fossils were kept in the building that housed the Bavarian State Collection of Paleontology. Unfortunately, on April 24/25 in 1944, the fossils, along with the original specimen of Carcharodontosaurus and most of Stromer's other collection of fossils, were destroyed during a British bombing raid in World War II, when Allied Forces attacked Berlin, Germany. The museum was an unfortunate casualty of the raid, as it was right across the street from the Nazi Party's headquarters (the intended target), and the museum's curator had refused to move the fossils to a safer location. New fossils of both dinosaurs would not be uncovered again until roughly 68 years later, though drawings and photos of the Spinosaurus specimens recovered by Stromer remained intact.

In 2014 and 2019, the nature of Spinosaurus was rendered even stranger when it was discovered by paleontologists Nizar Ibrahim and Paul Sereno to have possessed short hind legs, webbed feet, and a long, paddle-like tail similar to a newt or crocodile's and that the sail was probably more rectangular. These new discoveries suggested that Spinosaurus was better adapted to life in water than previously assumed, rendering its physical appearance in the Jurassic Park franchise outdated. Studies of the sub-adult specimen Sereno and Ibrahim recovered from their 2014 and 2019 expeditions to Morocco further suggested Spinosaurus preferred to hunt in shallow water. There is also some evidence that Oxalaia, a spinosaur from Brazil, is the same animal as Spinosaurus. If true, this suggests Spinosaurus was present in Africa and South America during the Cretaceous period.

Carnotaurus - Wikipedia

Carnotaurus was a lightly built, bipedal predator, measuring 7.5 to 8 m (24.6 to 26.2 ft) in length and weighing 1.3–2.1 metric tons (1.4–2.3 short tons; 1.3–2.1 long tons). As a theropod, Carnotaurus was highly specialized and distinctive.

CARNOTAURUS - Six Flags New England

Carnotaurus measured up to 30 feet (9 meters) long, 10 feet (3 meters) tall, and weighed up to 4000 pounds (2 tons). That's twice the size of a white rhino! The Carnotaurus had forward facing eyes, which was not common among dinosaurs. This would have given them good depth perception and binocular vision.

The "rottweiler effect" is especially large back part of the skull (postorbital area) where jaw muscles are located. The bigger the postorbital area - the stronger the bite force. Also, Carnotaurus' teeth are very unique design - they were very wide, and relatively blunt, resembling the railroad spike. These teeth are very suitable for crushing bone, making this carnivore's bite enormously lethal. His relatively large eyes were positioned right at the front of the skull, giving him binocular and tro-dimensional vision, what's pretty unusual in Dinosauria.

Originally discovered in 1900 in Colorado, Brachiosaurus was named in 1903 by Elmer Riggs of the Field Museum in Chicago. Brachiosaurus was once thought to have lived in both the United States and Africa (Tanzania) and Europe (Portugal) in the Jurassic. Scientists believed that Africa and North America were connected during the Jurassic. However, the African species of Brachiosaurus is now thought to be a different genus called Giraffatitan.

New studies by computer specialists suggest that Brachiosaurus may not have carried its neck angle up as high as was thought once. It may have carried the neck more at a 45 - 60 degree angle.

Rebel is a nickname of one of the two Spinoceratops seen in Jurassic World: Camp Cretaceous season 4.
