Lamiasaurus is an extinct genus of therapsids from the Tapinocephalus Assemblage Zone of the Karoo. It is known from an indeterminate jaw fragment that may be either titanosuchid or anteosaurid. [1]
Bradysaurus was a large, early and common pareiasaur, the fossils of which are known from the Tapinocephalus Assemblage Zone of the South African Karoo. Along with the similarly large dinocephalia, the bradysaurs constituted the herbivorous megafauna of the late Middle Permian Period. In life they were probably slow, clumsy and inoffensive animals, that had evolved a covering of armoured scutes to protect them against their predators, the gorgonopsians.
Tapinocephalus is an extinct genus of large herbivorous dinocephalians that lived during the Middle Permian Period. These stocky, barrel-bodied animals were characterised by a massive bony skull roof and short weak snout. It is thought that, like the rest of the members of its family, the animals engaged in head-butting intraspecific behavior, possibly for territory or mates.
The Tapinocephalus Assemblage Zone is a tetrapod assemblage zone or biozone which correlates to the middle Abrahamskraal Formation, Adelaide Subgroup of the Beaufort Group, a fossiliferous and geologically important geological Group of the Karoo Supergroup in South Africa. The thickest outcrops, reaching approximately 2,000 metres (6,600 ft), occur from Merweville and Leeu-Gamka in its southernmost exposures, from Sutherland through to Beaufort West where outcrops start to only be found in the south-east, north of Oudshoorn and Willowmore, reaching up to areas south of Graaff-Reinet. Its northernmost exposures occur around the towns Fraserburg and Victoria West. The Tapinocephalus Assemblage Zone is the second biozone of the Beaufort Group.
The Pristerognathus Assemblage Zone is a tetrapod assemblage zone or biozone which correlates to the upper Abrahamskraal Formation and lowermost Teekloof Formation, Adelaide Subgroup of the Beaufort Group, a fossiliferous and geologically important geological Group of the Karoo Supergroup in South Africa. The thickest outcrops, reaching not more than 300 metres (980 ft), occur just east of Sutherland through to Beaufort West in the south and Victoria West in the north. Exposures are also found west of Colesberg and south of Graaff-Reinet. The Pristerognathus Assemblage Zone is the third biozone of the Beaufort Group.
Struthiocephalus is an extinct genus of dinocephalian therapsids from the Permian of South Africa.
Keratocephalus is an extinct genus of tapinocephalian therapsids from the early Capitanian age of South Africa. It was found in the Lower and Middle Tapinocephalus Assemblage Zone of the Karoo deposits, in the Lower Beaufort Beds in Beaufort West
Bullacephalus is an extinct genus of biarmosuchian therapsids belonging to the family Burnetiidae. The type species B. jacksoni was named in 2003. It is known from a relatively complete skull and lower jaw, discovered in the Late Permian Tapinocephalus Assemblage Zone of the Beaufort Group of South Africa.
Brachyprosopus is an extinct genus of dicynodont therapsid from the middle Permian Tapinocephalus Assemblage Zone in the Abrahamskraal Formation belonging to the Beaufort Group of the Karoo Basin, South Africa.
Colobodectes is an extinct genus of dicynodont therapsid from the Tapinocephalus Assemblage Zone in the Abrahamskraal Formation, South Africa.
Eriphostoma is an extinct genus of gorgonopsian therapsids known from the Middle Permian of Tapinocephalus Assemblage Zone, South Africa. It has one known species, Eriphostoma microdon, and was first named by Robert Broom in 1911. It is the oldest known gorgonopsian and among the smallest and most basal members of the clade.
Elliotsmithia is a small varanopseid synapsid found from the late Middle Permian of South Africa. It is the sole basal synapsid "pelycosaur" known from the supercontinent Gondwana and only two specimens have been yielded to date. Its species name longiceps is derived from Latin, meaning "long head". Both known Elliotsmithia fossils were recovered from Abrahamskraal Formation rocks—within the boundaries of the Tapinocephalus Assemblage Zone—of the lower Beaufort Group.
Lanthanostegus is an extinct genus of non-mammalian synapsids from the Capitanian Tapinocephalus Assemblage Zone, Koonap Formation of South Africa.
Scullya is an extinct genus of titanosuchian therapsids. It is known from a poorly preserved snout that shows no clear titanosuchian characters. The presence of teeth on the palate may be an anteosaurian character. It is considered an indeterminable specimen.
Blattoidealestes is an extinct genus of therocephalian therapsid from the Middle Permian of South Africa. The type species Blattoidealestes gracilis was named by South African paleontologist Lieuwe Dirk Boonstra from the Tapinocephalus Assemblage Zone in 1954. Dating back to the Middle Permian, Blattoidealestes is one of the oldest therocephalians. It is similar in appearance to the small therocephalian Perplexisaurus from Russia, and may be closely related.
Icticephalus is an extinct genus of therocephalian therapsids from the Middle and Late Permian of South Africa. The type species Icticephalus polycynodon was named from the Tapinocephalus Assemblage Zone by South African paleontologist Robert Broom in 1915. Specimens of Icticephalus have also been described from the Cistecephalus Assemblage Zone. Broom originally placed Icticephalus in the Scaloposauridae, a group of very small therocephalians. Most scaloposaurids are now thought to be juvenile forms of other therocephalians, and Scaloposauridae is no longer recognized as a valid grouping. Icticephalus and other former scaloposaurids are now classified as basal members of Baurioidea.
Dinocynodon is an extinct genus of titanosuchian therapsids.
Enobius is an extinct genus of dinocephalian therapsids. It is known from jaw fragments that can only be identified as titanosuchian.
Pristerognathoides is an extinct genus of middle sized carnivorous therocephalians from the Tapinocephalus Assemblage Zone of South Africa. It is sometimes considered a synonym of Pristerognathus.
Tamboeria is an extinct genus of middle sized carnivorous therocephalians from the Tapinocephalus Assemblage Zone of South Africa.
Cynariognathus is an extinct genus of middle sized carnivorous therocephalian from the Tapinocephalus Assemblage Zone of South Africa. It is sometimes considered a synonym of Pristerognathus.
