Archegosaurus was a genus of temnospondyl amphibian. It lived in the early Permian period. Its name means "founder of the reptile race" because at the time of its discovery it was thought to have been a crocodile, but it was an amphibian. However, it did look a lot like a crocodile. Stomach contents show that Archegosaurus hunted Acanthodes, a prehistoric fish. It grew to about 5 feet long, or roughly 2 meters.
