Therocephalia genera

Bauria is an extinct genus 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.

Purlovia is an extinct genus of herbivorous therocephalian therapsids from the Late Permian of Russia. Fossils have been found from the Tonshayevsky District of Nizhny Novgorod Oblast. The type species of Purlovia, P. maxima, was named in 2011. left|thumb|Holotype skull In comparison to other therocephalians, Purlovia had a very wide skull due to a widened temporal region. Viewed from above, it looks roughly triangular. The skull is about long, with nearly half its length in the postorbital region behind the eye sockets. It has large canine teeth and smaller buccal, or cheek teeth, along the t

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. Ericiolacerta

Lycosuchus is a genus of early therocephalian (an extinct type of therapsid, the group that modern mammals belong to) that lived roughly 260–258 million years ago, straddling the boundary of the Middle and Late Permian period, from what is now the Karoo Basin of South Africa. The type and only species is L. vanderrieti, named by paleontologist Robert Broom in 1903. Lycosuchus is known from a handful of well-preserved specimens mostly preserving the skull and lower jaw; the holotype specimen itself being a nearly complete and undistorted occluded skull and jaws. Other specimens have revealed mo

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.

thumb|left|Restoration Annatherapsidus is an extinct genus of therocephalians from the Upper Permian of Russia. It was a fairly small animal with a length of 91 cm and a 22 cm skull. It was originally named Anna petri, but the genus name was already taken, so it was renamed to Annatherapsidus.

Scylacosuchus is an extinct genus of therocephalian therapsids. It was a predatory eutherocephalian that lived in Lopingian epoch. Its fossils were found in Orenburg Oblast of Russia. The type species is Scylacosuchus orenburgensis.

Gorynychus is a genus of therocephalian from the mid-Permian from Kotelnich, Russia. The genus contains two species, G. masyutinae and G. sundyrensis. It was named after the three-headed dragon Zmey Gorynych (Змей Горыныч) from Russian mythology.

Simorhinella is an extinct genus of therocephalian therapsids from the Guadalupian, or Middle Permian, of South Africa. It is includes only a single species, Simorhinella baini, named by South African paleontologist Robert Broom in 1915. Broom named Simorhinella on the basis of a single small fossil from the British Museum of Natural History collected in 1878 that includes the skull and jaws from the eye sockets forward of a young juvenile. The skull is unusual in that it has an extremely short and broad snout, unlike the longer and narrower snouts of most other early therocephalians. Because

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

Porosteognathus is an extinct genus of therocephalian therapsids. Remains have been found at Isheevo in Russia (Republic of Tatarstan). It is known from the Middle Permian.

Distinguished from the Late Permian junior synonym of Akidnognathus "Hofmeyria".

Megawhaitsia is an extinct genus of large therocephalian therapsids who lived during the Late Permian (Wuchiapingian) in what is now Eastern Europe. The only known species is M. patrichae, described in 2008 from several fossils discovered in various oblasts of European Russia. The fossils are representative of a large animal whose skull size is estimated to be long.

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.

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.

Trochosaurus (from , 'badger' and , 'lizard') is a dubious genus of therocephalian therapsid from South Africa, to which various species were once assigned. The genus was based upon multiple weathered and distorted fossils of therocephalians of the family Lycosuchidae. Like other lycosuchids, specimens placed in Trochosaurus have only five large incisors in each premaxilla, seemingly two functional "double canines" in each maxilla (of which the second was supposedly slightly larger in Trochosaurus), and few postcanines. However, the fossils lack any further diagnostic traits to justify referri

Moschowhaitsia is an extinct genus of therocephalian therapsids from the Late Permian (Guadalupian) of Russia and China. The type species, Moschowhaitsia vjuschkovi, was discovered in the Changxingian-aged Archosaurus Assemblage Zone of Russia and named in 1963 by Russian palaeontologist Leonid Petrovich Tatarinov. A second species was discovered in Jingtai County of Gansu, China in 2020 and named as M. lidaqingi in 2023 by Jun Liu and Fernando Abdala, the first whaitsiid therocephalian to be discovered in China. It was among the larger carnivores in the faunal assemblages it occurred in, with

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.

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

Scymnosaurus is a dubious genus of therocephalian therapsids from the Middle Permian of what is now South Africa based upon the fossils of large, but indeterminate, early therocephalians. The genus and its type species S. ferox was named by Robert Broom in 1903, followed by S. watsoni in 1915. A third species, S. major, was named by Lieuwe Dirk Boonstra in 1954, who also referred many more specimens to the genus as Scymnosaurus sp.

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

Ictidosuchus is an extinct genus of therocephalian therapsids.

Ictidostoma is an extinct genus of non-mammalian synapsids known from the Tropidostoma Assemblage Zone.

Viatkosuchus is an extinct genus of therocephalians known from the Late Capitanian–Wuchiapingian Deltavjatia Assemblage Zone.

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.

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

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.

Akidnognathus is an extinct genus of therocephalians.

Caodeyao is a genus of therocephalian that lived in what is now China during the late Permian. It was found in the Naobaogou Formation. It contains one species, Caodeyao liuyufengi, named in 2020 by Jun Liu and Fernando Abdala. The authors found that its closest relative is Purlovia from Russia, forming with it an exclusively Laurasian clade.
