Excerpt: See "Taxonomy" Therocephalians are an extinct suborder of carnivorous eutheriodont therapsids that lived from the middle and late Permian into the Triassic 265.0245.0 Ma existing for approximately . The therocephalians ("beast-heads") are named after their large skulls, which, along with the structure of their teeth, suggest that they were successful carnivores. Like other non-mammalian synapsids, therocephalians are described as mammal-like reptiles, although In fact, Therocephalia is the group most closely related to the cynodonts, which gave rise to the mammals. This relationship takes evidence in a variety of anatomical features, possibly including whiskers and hair. There remain many unanswered questions about the phylogeny, anatomy, and physiology of therocephalians. The fossils of therocephalians are numerous in the Karoo of South Africa, but have also been found in Russia, China, and Antarctica. Early therocephalian fossils discovered in Middle Permian deposits of South Africa support a Gondwanan origin for the group, which seems to have spread quickly throughout the world. Although almost every therocephalian lineage ended during the great PermianTriassic extincti...More: http: //booksllc.net/?id=484870
