How are mammal-like reptiles similar to mammals?
Mammal-like reptiles share many characteristics of mammals. They have a similar skull to mammals in that they have a single hole in the side of the skull behind the eye socket. This puts them in a common group of animals called the Synapsids. Their teeth are differentiated into molars, canines, and incisors, similar to mammal’s teeth. Their legs are directly beneath their body, unlike reptiles whose limbs are sprawled out to the side of the body.
