RegisaurusRegisaurus ("Rex's lizard", named after Francis Rex Parrington) is an extinct genus of small carnivorous therocephalian. It is known from a single described species, the type speciesRegisaurus jacobi, from the Early TriassicLystrosaurus Assemblage Zone of South Africa, although at least one undescribed species is also known. DescriptionIt was a rather derived baurioid, with a robust skull, short tail, long limbs and relatively large canines.
BauriaBauria is an extinctgenus of the suborder Therocephalia that existed during the Early and Middle Triassic period, around 246-251 million years ago. It belonged to the family Bauriidae. Bauria was probably a herbivore or omnivore. It lived in South Africa, specifically in the Burgersdorp Formation in South Africa. TaxonomyBauria was named by Robert Broom in 1909 and found at Winnaarsbaken, South Africa.
TherocephaliaTherocephalia is an extinct group of therapsids (mammals and their close extinct relatives) from the Permian and Triassic periods. The therocephalians ("beast-heads") are named after their large skulls, which, along with the structure of their teeth, suggest that they were carnivores. Like other non-mammalian synapsids, therocephalians were once described as "mammal-like reptiles".
Robert BroomRobert BroomFRSFRSE (30 November 1866 – 6 April 1951) was a British-South African medical doctor and palaeontologist. He qualified as a medical practitioner in 1895 and received his DSc in 1905 from the University of Glasgow. From 1903 to 1910, he was professor of zoology and geology at Victoria College, Stellenbosch, South Africa, and subsequently he became keeper of vertebrate palaeontology at the South African Museum, Cape Town.Alfred RomerAlfred Sherwood Romer (December 28, 1894 – November 5, 1973) was an American paleontologist and biologist and a specialist in vertebrate evolution.
ScaloposaurusScaloposaurus is an extinctgenus of carnivoroustherocephalians living during the Permian 259.0—254.0 Ma existing for approximately 5 million years. TaxonomyScaloposaurus was named by Owen (1876). It was assigned to Therocephalia by Broom (1913); and to Scaloposauridae by Carroll (1988).D. M. S. WatsonProf David Meredith Seares Watson FRS FGS HFRSE LLD (18 June 1886 – 23 July 1973) was the Jodrell Professor of Zoology and Comparative Anatomy at University College, London from 1921 to 1951.
TherapsidaTherapsida is a major group of eupelycosauriansynapsids. It includes mammals, as well as their ancestors and close relatives. Many defining traits of modern mammals had their origins within early therapsids. Changes in skeletal structure brought their limbs underneath their body mass which resulted in a more "standing" quadrupedal posture, as opposed to the lower sprawling posture of many reptiles and amphibians.*As an Amazon Associate I earn from qualifying purchases.
