The Edaphosaurus was a large herbivorous synapsid that lived during the end of the Pennsylvanian period and into the Permian period. Like the Dimetrodon, the Edaphosaurus had a large back sail, likely for thermoregulation and social display. The species in the Edaphosaurus genus could grow anywhere between 1.6- 11.5 feet in length, but each had a round body, stocky legs, and a small head.
