Reptiles are tetrapod animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders , historically combined with that of modern amphibians , is called herpetology .
The Lepidosauria (from Greek meaning scaled lizards) are reptiles with overlapping scales. This subclass includes Squamata and Rhynchocephalia. It is a monophyletic group and therefore contains all descendants of a common ancestor. [13]

Similarly, climate warming that occurred millions of years ago helped reptiles evolve faster, diversify, and conquer the world, says a new study. Researchers have long believed the extinction of ...
