1. pelycosaur

   Pelycosaurs are a group of primitive, extinct terrestrial reptiles that lived from the late Carboniferous to the early Permian period. They are characterized by a sprawling gait and many had a sail-like structure on their back, most famously seen in the species Dimetrodon. It is believed that they are the ancestors of mammals.

1. Pelycosaur

   The pelycosaurs are an informal grouping composed of basal or primitive Late Paleozoic synapsid amniotes. Some species were quite large and could grow up to 3 meters or more, although most species were much smaller. Because more advanced groups of synapsids evolved directly from 'pelycosaurs', the term had fallen out of favor among scientists by the 21st century; and is only used informally, if at all, in the modern scientific literature.
