Description
Dimetrodon, illustration. This extinct prehistoric animal is a synapsid, an early form of the evolution from reptiles to mammals. It lived during the 295 to 272 million years ago, during the Early Permian. Most of the known fossils have been found in Texas, USA. Around 3 metres in length, it was one of the dominant land predators at the time. The neural spine sail may have been for thermoregulation, but is also thought to have been used for mating displays. The early synapsids, such as this pelycosaur synapsid, are sometimes described as mammal-like reptiles.
