Reptiles - Class Reptilia

Reptiles (Class Reptilia) are cold-blooded vertebrates that diverged from ancestral amphibians about 340 million years ago. Ancient reptiles diverged into two distinct lineages, one that gave rise to modern mammals and the other gave rise to modern reptiles and birds. Modern reptiles include turtles, snakes, lizards, worm lizards, alligators, crocodiles, caimans, and gavials.
