Dimetrodon is an extinct genus of non-mammalian synapsid that lived during the Early Permian, around 295–272 million years ago. The most prominent feature of Dimetrodon 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 fossils have been found in the Southwestern United States, the majority coming from a geological deposit called the Red Beds of Texas and Oklahoma. Over a dozen species have been named in the genus.Dimetrodon is often mistaken for a dinosaur or as a contemporary of dinosaurs in popular culture, but it became extinct some 40 million years before the first appearance of dinosaurs. Reptile-like in appearance and physiology, Dimetrodon was probably one of the apex predators of its ecosystems, feeding on fish and tetrapods, including reptiles and amphibians. The sail of Dimetrodon may have been used to stabilize its spine or to heat and cool its body as a form of thermoregulation. Dimetrodon 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 lbs. The larger species of Dimetrodon were among the largest predators of the Early Permian.The sail of Dimetrodon is formed by elongated neural spines projecting from the vertebrae. Each spine varies in cross-sectional shape from its base to its tip in what is known as "dimetrodont" differentiation. DM011
