Description
Reconstructed fossil skeleton of an early Permian pelycosaur, Edaphosaurus boanerges, found in the Bell Plains Formation, Lake Kickapoo, Archer County, Texas, USA. This individual was approximately 8 feet in length from head to the tip of its tail. Edaphosaurs were herbivorous reptiles that lived in wet swampy areas during the late Carboniferous and early Permian periods, well before dinosaurs evolved. Pelycosaurs were primitive synapsid reptiles, presumably ancestors of the therapsids, which led to mammals. Like Dimetrodon, Edaphosaurus was a sailback, and its sail is believed to have functioned in thermoregulation and possibly display.
