Edaphosaurus is not a Dinosaur
Edaphosaurus, like Dimetrodon, is sometimes referred to as a “sail-backed reptile”. It is sometimes included in dinosaur model sets. However, Edaphosaurus was not a dinosaur. This reptile was a synapsid, a member of a group of reptiles that has a single opening (fenestra) just behind the eye socket in the skull. Dinosaurs, along with lizards, crocodiles, Aves (birds) and marine reptiles such as the Plesiosauria, were diapsids. Diapsids have two holes on each side of the skull. Mammals are also synapsids, so Edaphosaurus was ironically more closely related to mammals like us than to the Dinosauria, although the term “mammal-like” reptile that is often applied to this ancient reptile is very misleading and not accurate.
Edaphosaurus Lived During the Permian Geological Period, Long Before the First Dinosaurs
