Age of Reptiles

200 million years ago was the dinosaur age, which is considered as the ruling age of the reptiles. Only dinosaurs were dominant at that time along with some smaller species of reptiles.

These reptiles are cold blooded animals and mostly vertebrates. The reptiles are found both on land and water.
