History of Reptiles...

Reptiles arose about 310-320 million years ago during the Carboniferous period.

 

Reptiles are defined as animals that have scales, lay land based hard shelled eggs, and possessing ectothermic metabolisms. Today reptiles generally rank low in most ecological food chains, containing very few apex predators, but many examples of apex reptiles have existed in the past. Although reptiles have lower species variation than in the past, they have an extremely diverse evolutionary history that has led to biological successes such as dinosaurs, mammals, and birds.
