Dimetrodon or Dimetrodon Limbatus meaning “two measures of teeth” is an extinct genus of synapsids that lived during the Cisuralian (Early Permian), around 295–272 million years ago. 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.
Dimetrodon or Dimetrodon Limbatus meaning “two measures of teeth”) is an extinct genus of non-mammalian synapsids that lived during the Cisuralian (Early Permian), around 295–272 million years ago. It is a member of the family Sphenacodontidae.
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. More recently, fossils have been found in Germany. Over a dozen species have been named since the genus was first described in 1878.
Dimetrodon or Dimetrodon Limbatus was probably one of the apex predators of the Cisuralian ecosystems, feeding on fish and tetrapods, including reptiles and amphibians. Smaller Dimetrodon species may have had different ecological roles. The sail of Dimetrodon or Dimetrodon Limbatus may have been used to stabilize its spine or to heat and cool its body as a form of thermoregulation.
Some recent studies argue that the sail would have been ineffective at removing heat from the body due to large species being discovered with small sails and small species being discovered with large sails, essentially ruling out heat regulation as its main purpose. The sail was most likely used in courtship display with methods such as threatening rivals or showing off to potential mates.
