Dimetrodon Limbatus meaning “two measures of teeth”) is an extinct genus of non-mammalian synapsids that lived during the Cisuralian (Early Permian), around 295 to 272 million years ago.

Dimetrodon Limbatus is a member of the family Sphenacodontidae. The most prominent feature is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It walked on four legs and had a tall, curved skull with large teeth of different sizes set along the jaws.

Most of Dimetrodon Limbatus fossils have been found in the southwestern United States, the majority coming from a geological deposit called the Red Beds of Texas and Oklahoma. More recently, fossils have been found in Germany. Over a dozen species have been named since the genus was first described in 1878.

Dimetrodon Limbatus was a quadrupedal, sail-backed synapsid. Most Dimetrodon species ranged in length from 6 to 15 ft. and are estimated to have weighed between 60 and 550 lb.

The largest known species is D. angelensis at around 13 ft. The larger species of Dimetrodon were among the largest predators of the Early Permian. Although some Dimetrodon Limbatus species could grow very large, many juvenile specimens are known.

The skull of Dimetrodon Limbatus is tall and compressed laterally, or side-to-side. The eye sockets are positioned high and far back in the skull. Behind each eye socket is a single hole called an infratemporal fenestra.

An additional hole in the skull, the supratemporal fenestra, can be seen when viewed from above. The back of the skull  is oriented at a slight upward angle. The upper margin of the skull slopes downward in a convex arc to the tip of the snout.
