Synapsida was a pre-mammalian reptile and believed to be the ancestor of mammals due to the similar shape of their skulls. Synapsida were the dominant land animals of the Late Carboniferous (Pennsylvanian) period to the Permian period which we start to see from about 300 million years ago, though they were more abundant and more diversified in the beginning of the Permian period, around 270 million years ago.
