Scylacosauridae
Scylacosauridae is an extinct family of therocephalian therapsids. Scylacosaurids lived during the Permian period and were among the most basal therocephalians. The family was named by South African paleontologist Robert Broom in 1903. Scylacosaurids have long snouts and unusual saber-like canine teeth.

Karrowalteria
''Glanosuchus'' is a genus of scylacosaurid therocephalian from the Late Permian of South Africa. The type species ''G. macrops'' was named by Robert Broom in 1904. ''Glanosuchus'' had a middle ear structure that was intermediate between that of early therapsids and mammals. Ridges in the nasal cavity of ''Glanosuchus'' suggest it had an at least partially endothermic metabolism similar to modern mammals. Description ''Glanosuchus macrops'' was first described in 1904 by South African paleontologist Robert Broom, who named the genus and species on the basis of a nearly complete holotype skull. The skull has been distorted during fossilization and the bone is indistinguishable from the surrounding matrix in some parts. In illustrating the holotype, Broom chose to reconstruct the skull of the species rather than draw the actual specimen. The skull of ''Glanosuchus'' is about long. ''Glanosuchus'' probably grew to around in length. Like other early therocephalians, ''Glanosuchus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ictidosaurus
''Ictidosaurus'' was a therapsid genus found in the Abrahamskraal Formation of South Africa, which lived during the middle Permian period. Fossils of the type species were found in the ''Tapinocephalus'' (Capitanian age, 265.8-260.4 Ma), and the base of the ''Eodicynodon'' (Wordian age, 268–265.8 Ma) assembly zones, of the Karoo Basin. Older classifications of the species, along with many other specimens found in the Iziko South African Museum archives, were originally classified within therocephalian family names, in this case the Ictidosauridae, which has been reclassified as belonging to the Scylacosauridae. The type species is ''I. angusticeps''. Description Type specimen The holotype was of the ''Ictidosaurus angusticeps'' labeled SAM-PK-630 (NMQR 2910), found in the Tapinocephalus assembly zone. The skull measured 168 mm from snout to posterior of the left mandible, 41 mm across the skull in-between the canines, and 41 mm in height, and has been heavily disturbed by f ...

Scymnosaurus
''Scymnosaurus'' ( 'lion cub' + , 'lizard') is an extinct genus of therocephalian therapsids, first described by Robert Broom in 1903. There are three species that still take the name ''Scymnosaurus'', ''S. ferox'', ''S. watsoni'' and ''S. major'', with a fourth, ''S. warreni'', now identified as ''Moschorhinus warreni''. Each of these have now been reclassified into Lycosuchidae ''incertae sedis''. ''Scymnosaurus'' is estimated to have been approximately the size of the modern day hyena, and possessed teeth suggesting that it was carnivorous. ''S. ferox'' was initially described as the second largest therocephalian, until the discovery of ''S.'' ''major'', which is likely the largest therocephalian. It is notable that throughout the 19th century, Broom was involved with the work done with therocephalians and their classifications, and re-classifications, with paper and book publications ranging from 1903 to 1950.

Pristerognathus
''Pristerognathus'' is an extinct genus of therocephalian, known from the late Middle Permian (Capitanian) of South Africa.F. Abdala, B. Rubidge, and J. van der Heever, "The oldest therocephalians (Therapsida, Eutheriodonta) and the early diversification of Therapsida," ''Palaeontology'', 51, 1011-1024 (2008) It lends its name to the Pristerognathus Assemblage Zone of the Beaufort Group of South African geological strata. ''Pristerognathus'' was a medium-sized therocephalian with a skull and a total length up to . These animals were roughly dog-sized, and are characterized by long, narrow skulls with large canines. They are likely to have lived in woodlands, and preyed on smaller therapsids and millerettids of the time. ''Pristerognathus'' was described in 1895 by Harry Seeley who named the type species ''Pristerognathus polyodon''. Many other species were named in the years following, such as ''P. baini'', ''P. minor'', and ''P. vanderbyli'', however, they have all since been ...
