Baurioidea

thumb|left|Ericiolacerta Ericiolacerta is an extinct genus of small therocephalian therapsids from the early Triassic of South Africa and Antarctica. Ericiolacerta, meaning "hedgehog lizard" (from the Latin ericius, "hedgehon" and lacerta, "lizard"), was named by D. M. S. Watson in 1931. The species E. parva is known from the holotype specimen which consists of a nearly complete skeleton found in the Lystrosaurus Assemblage Zone within the Katberg Formation of the Beaufort Group in South Africa, and from a partial jaw found in the Lower Triassic Fremouw Formation in Antarctica.

Ictidosuchoides is an extinct genus of ictidosuchid therocephalians. Fossils have been found from the Karoo Basin in South Africa. The genus was previously thought to have been one of the few therocephalians to have survived the Permian-Triassic extinction event in this area, but the putative early Triassic specimens have since been attributed to Promoschorhynchus.

Scaloposaurus is an extinct genus of carnivorous therocephalians living during the Permian 259.0—254.0 Ma existing for approximately .

Baurioidea is a superfamily of therocephalian therapsids. It includes advanced therocephalians such as Regisaurus and Bauria. The superfamily was named by South African paleontologist Robert Broom in 1911. Bauriamorpha, named by D. M. S. Watson and Alfred Romer in 1956, is a junior synonym of Baurioidea.

Tetracynodon is an extinct genus of therocephalian. Fossils of Tetracynodon have been found in the Karoo Basin of South Africa. Two species are known: the type species T. tenuis from the Late Permian and the species T. darti from the Early Triassic. Both species were small-bodied and probably fed on insects and small vertebrates. Although Tetracynodon is more closely related to mammals than to reptiles, its braincase is very primitive and more resembles that of modern amphibians and reptiles than of mammals.

Karenites is an extinct genus of therocephalian therapsids from the Late Permian of Russia. The only species is Karenites ornamentatus, named in 1995. Several fossil specimens are known from the town of Kotelnich in Kirov Oblast.

Silphedosuchus is an extinct genus of therocephalian therapsids from the Early Triassic of Russia. It is a member of the family Ericiolacertidae, along with the genus Ericiolacerta from South Africa and Antarctica. The type species Silphedosuchus orenburgensis was described in 1977 on the basis of a single holotype skull from Orenburg Oblast.

Bauriidae is an extinct family of therocephalian therapsids. Bauriids were the latest-surviving group of therocephalians after the Permian–Triassic extinction event, going extinct in the Middle Triassic. They are among the most advanced eutherocephalians and possess several mammal-like features such as a secondary palate and wide postcanine teeth at the back of the jaws (analogous to mammalian molars). Unlike other therocephalians, bauriids were herbivorous. They were also smaller than earlier members of the group. Two subfamilies are classified within Bauriidae: Nothogomphodontinae and Baurii

Microgomphodon is an extinct genus of therocephalian therapsid from the Middle Triassic of South Africa and Namibia. Only one species of Microgomphodon, M. oligocynus, is currently recognized. With fossils present in the Cynognathus Assemblage Zone (CAZ) of the Burgersdorp Formation in South Africa and Omingonde Formation of Namibia and ranging in age from late Olenekian to Anisian, it is one of the most geographically and temporally widespread therocephalian species. Moreover, its occurrence in the upper Omigonde Formation of Namibia makes Microgomphodon the latest-surviving therocephalian. M

Ericiolacertidae is a family of therocephalian therapsids. The family living in the earliest Triassic after the Permian-Triassic extinction event. Genera are: Ericiolacerta found in the Fremouw Formation of Antarctica and the Normandien Formation of South Africa, Pedaeosaurus found in the Fremouw Formation of Antarctica and Silphedosuchus, from the Petropavlovka Formation of Russia, east of the Urals. The family is composed of carnivores.

Nothogomphodon is a genus of therocephalian therapsids. It is classified within the family Bauriidae and placed within its own subfamily, Nothogomphodontinae.

Regisaurus ("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 species Regisaurus jacobi, from the Early Triassic Lystrosaurus Assemblage Zone of South Africa, although at least one undescribed species is also known.

Scalopodontes is an extinct genus of therocephalian which existed in Russia during the Late Permian period. The type species is Scalopodontes kotelnichi. Fossils have been found in the Sokolki Assemblage Zone of the Urpalov Formation.

Ictidosuchops is a genus of therocephalian therapsids. There are currently two named species: Ictidosuchops intermedius and Ictidosuchops baurioides.

Regisauridae is an extinct family of small carnivorous theriodonts from the Late Permian and Early Triassic of South Africa and China.

Lycideops is an extinct genus of therocephalians from the Late Permian of South Africa. The type species is Lycideops longiceps, named in 1931 by South African paleontologist Robert Broom. Fossils of Lycideops come from the Dicynodon Assemblage Zone of the Beaufort Group. Lycideops is a member of the family Lycideopidae. Like other lycideopids, Lycideops has a long snout.

Ictidosuchus is an extinct genus of therocephalian therapsids.

Lycideopidae is an extinct family of therocephalians from the Late Permian and Early Triassic of South Africa.

Malasaurus is an extinct genus of therocephalian therapsids which lived in south-eastern Finland and north-western Russia. The type species is Malasaurus germanus.

Choerosaurus is an extinct genus of therocephalian therapsids from the Late Permian of South Africa. The type species Choerosaurus dejageri was named by South African paleontologist Sidney H. Haughton from the Tropidostoma Assemblage Zone in 1929.

Chlynovia is an extinct genus of therocephalian therapsids from the Late Permian of Russia. The type species is C. serridentatus, named in 2000. Chlynovia was originally classified within Scaloposauria, a group of therocephalians characterized by their small size and lightly built skulls. Scaloposaurians are no longer recognized as a true grouping, but instead represent the juvenile forms of many types of therocephalians. Chlynovia was placed in the family Perplexisauridae along with Perplexisaurus, but both therocephalians are now placed in the family Ictidosuchidae.
