This era accelerated the growth and evolution of reptiles because of the increasingly cold, dry climate of the late Carboniferous period.

The south was cold and arid, with much of the region frozen under ice caps. Northern areas suffered increasingly from intense heat and great seasonal fluctuations between wet and dry conditions. The lush swamp forests of the Carboniferous were gradually replaced by conifers, seed ferns, and other drought-resistant plants.

This period is mostly dominated by Sauropsids and Synapsids.

It is known as the Mesozoic Era's earliest and shortest period.

A transitional time between the late Palaeozoic Era, when synapsids, or mammalian-like reptiles, dominated, and the Mesozoic Era, when archosaurian reptiles, which include dinosaurs, came to predominate.

The diversity and dominance of life on Earth shifted dramatically throughout this period, ushering in the development of several well-known animal groupings.

This period marks the start of "The Age of Reptiles"

During this period the supercontinent Pangea split apart, allowing for the eventual development of what is now the central Atlantic Ocean and the Gulf of Mexico. Heightened plate tectonic movement led to significant volcanic activity, mountain-building events, and the attachment of islands onto continents.

In Triassic terrestrial ecosystems, synapsids and therapsids, the ancestors of modern mammals and their relatives, were dominant. By the start of the Jurassic, these groups became rare. Instead, the archosaurs (dinosaurs, crocodiles, and pterosaurs) were the dominant terrestrial vertebrates.

Early amphibians appear to have been hardest hit by this event. The relative success of reptiles may have been due to physical adaptations in which they differed from amphibians.
Firstly, the hard-shelled eggs of reptiles could be laid on dry land. Secondly, reptiles possess protective scales that help them retain moisture.

This event kickstarted the evolution of reptiles.

True archosaurs are classified into two groups. Crocodiles and any other archosaurs that are more closely linked to crocodiles than to birds belong to the Pseudosuchia branch. The Ornithosuchia, the second archosaurian branch, encompasses birds and all archosaurs that are more closely related to birds than to crocodiles.

Although most archosaurs died extinct by the end of the Triassic, dinosaurs, crocodiles, and pterosaurs survived and thrived during the Jurassic and Cretaceous periods.

The other two are the Mesozoic and Paleozoic Eras. The Cenozoic spans only about 65 million years, from the end of the Cretaceous Period and the extinction of non-avian dinosaurs to the present.  The Cenozoic is sometimes called the Age of Mammals, because the largest land animals have been mammals during that time.

-The Cenozoic Era is divided into three periods:

Paleogene (65.5 to 23.02 million years ago)
Neogene (23.03 to 2.6 million years ago)
Quaternary (2.6 million years ago to now)

-This is a misnomer for several reasons. First, the history of mammals began long before the Cenozoic began. Second, the diversity of life during the Cenozoic is far wider than mammals.

-The Cenozoic could have been called the "Age of Flowering Plants" or the "Age of Insects" or the "Age of Teleost Fish" or the "Age of Birds" just as accurately.

It is medium sized with adult males reaching a maximum length of 3.5 metres (11.4 feet). It is the most terrestrial of all the crocodilians and has big, strong legs, which gives it a unique high walk. It is often regarded as the most aggressive species of crocodile. In contrast to their usual solitary hunting habits, Cuban crocodiles in captivity developed pack-hunting behaviour. Already ferocious on their own, these animals pose a formidable threat as a pack.

It is characterized by its elongated snout and the sail like mounted on its back.

This gigantic reptile feeds on aquatic animals in its time by using its crocodile like snout to catch its preys. 
It was discovered while German paleontologist Ernst Stromer led a fossil dig on Egypt.

He was famously known as a paleontologist that led a dig on Egypt and discovered a very important piece of fossils.
He discovered the boned of the Spinosaurus, a very large dinosaur from the late cretaceous period. It was so large that it defeated the size of the previously well known Tyrannosaurus Rex.

Ichthyosaurs had a very wide geographic distribution, and their fossil remains span almost the entire Mesozoic Era (251 million to 65.5 million years ago), but they were most abundant and diverse during the Triassic and Jurassic periods .

The exact nature of this catastrophic event is still open to scientific debate. Evidence suggests an asteroid impact was the main culprit. Volcanic eruptions that caused large-scale climate change may also have been involved, together with more gradual changes to Earth's climate that happened over millions of years.

Whatever the causes, the huge extinction that ended the age of the dinosaur left gaps in ecosystems around the world. These were subsequently filled by the only dinosaurs to survive - birds - and mammals, both of which went on to evolve rapidly.

Lizards and snakes, both distant relatives of dinosaurs, also survived and continued to evolve from that period of time into what we now see today.

Other factors include habitat encroachment, hunting, climate change, pollution and genetic mutations are being credited as the major causes of this mass extinction.

The Holocene Extinction is also called the Anthropocene, or Age of Man extinction since it is directly linked to human evolvement to the changes of the planet. There has been a significant decline of biodiversity due to mankind which could lead to the untimely elimination of not just individual species but whole lines of phyla if not checked in time.

It was discovered by a German-Madagascan expedition team in northern Madagascar. The species’ closest relative is the slightly larger Brookesia micra, whose discovery was announced in 2012.
Scientists assume that the lizard’s habitat is small, as is the case for similar subspecies.
