Petrolacosaurus was one of the earliest reptiles to evolve. It would have fallen prey to large amphibians (Proterogyrinus) or very large bugs (Meganeura).

Petrolacosaurus would have evolved from the earliest amphibians (Hynerpeton), but the main differences include scaly skin, hard shelled eggs and clawed feet.
