Scaloposauridae
Baurioidea is a superfamily (zoology), superfamily of therocephalian therapsids. It includes advanced therocephalians such as ''Regisaurus'' and ''Bauria''. The superfamily was named by South African people, 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. Many baurioids were once placed in a group called Scaloposauria. Scaloposaurs were characterized by their small size and reduced postorbital bar (a strut of bone behind the eye socket). Scaloposauria is no longer recognized as a valid taxon because it likely represents juvenile forms of many groups of therocephalians. Most scaloposaurs, including ''Scaloposaurus'' and ''Regisaurus'', are now classified in various positions within Bauroidea. Many therocephalians once classified as scaloposaurians are now considered basal baurioids. The classification of these species is uncertain, as there have been no comprehensive phylogenetic ...

Icticephalus
''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 Robert Broom Fellow of the Royal Society, FRS FRSE (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 ... 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. References ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scalopodon
''Scalopodon'' is an extinct genus of therocephalian therapsids from the Late Permian of Russia. The type species ''Scalopodon tenuisfrons'' was named in 1999 from the Kotelnichsky District of Kirov Oblast. ''Scalopodon'' is known from a single fragmentary holotype specimen including the back of the skull, the left side of the lower jaw and isolated postorbital and prefrontal bones. The skull was found in the ''Deltavjatia'' Assemblage Zone, which dates back to the early Wuchiapingian about 260 million years ago. Distinguishing features of ''Scalopodon'' include narrow frontal bones and a distinctive sagittal crest along the parietal region at the back of the skull. ''Scalopodon'' was originally classified in the family Scaloposauridae Baurioidea is a superfamily (zoology), superfamily of therocephalian therapsids.

Scalopocephalus
''Scalopocephalus'' is an extinct genus of therocephalian therapsids from the Late Permian of South Africa. German paleontologist Friedrich von Huene discovered the holotype skull of ''Scalopocephalus'' from the ''Cistecephalus'' Assemblage Zone in 1924 and named the type species ''Scalopocephalus watsonianus'' in 1937. ''Scalopocephalus'' is similar in appearance to ''Scaloposaurus'' and was first classified in the family Scaloposauridae Baurioidea is a superfamily (zoology), superfamily of therocephalian therapsids.

Ictidodon
''Ictidodon'' is an extinct genus of therocephalian therapsids from the Late Permian of South Africa. The type species ''Ictidodon agilis'' was named by South African paleontologist Robert Broom in 1925. Broom classified ''Ictidodon'' in the Scaloposauridae, a group of small-bodied therocephalians that are now thought to be juvenile forms of larger therocephalians. ''Ictidodon'' and many other scaloposaurids are now classified as basal members of the clade In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants.

Silpholestes
''Silpholestes'' is an extinct genus of therocephalian therapsids from the Late Permian of South Africa. The type species ''Silpholestes jackae'' was named by South African paleontologist Robert Broom in 1948 from the ''Cistecephalus'' Assemblage Zone. Classification ''Silpholestes'' lends its name to Silpholestidae, a family that traditionally encompassed many small therocephalians. Silpholestidae was first named by paleontologists D. M. S. Watson and Alfred Romer in 1956. In addition to ''Silpholestes'', the genera '' Ictidodraco'', '' Scaloporhinus'', '' Silphictidoides'', and '' Tetracynodon'' were all classified in Silpholestidae. Therocephalians that were once classified in this family are all very small, and have elongated and pointed snouts. Silpholestids were characterized by their short temporal openings at the back of the skull; in most therocephalians, these openings are very large and occupy much of the skull. Silpholestids were also distinguished by their wide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhigosaurus
''Rhigosaurus glacialis'' is a species of therocephalian therapsid. Its fossilized remains have been found in the Fremouw Formation of Antarctica and Australia. Part of a juvenile skull was found near Mount Kenyon, Antarctica. The holotype of the partial skull shows evidence of promiment upper and lower canine teeth. The genus name ''Rhigosaurus'' comes from the Greek , meaning cold, and , meaning lizard or reptile. The name was coined by Edwin Harris Colbert and James William Kitching, who described the species in 1981 based on a fossil found in 1970-1971. They described it as robust and small in size. The fossil skull was long and across at the widest point. Modern paleontologists such as Christian Sidor consider the species a nomen dubium In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application.

''Ictidosuchoides'' is an extinct genus of ictidosuchid therocephalians. Fossils have been found from the Karoo Basin in South Africa. The genus is known to have been one of the few therocephalians to have survived the Permian-Triassic extinction event in this area, although its numbers were quite low after the extinction.Ward, P.

Chlynovia
''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. ''Chlynovia'' was found in the Urpalov Formation in the Kirov region of Russia. Remains of ''Chlynovia'' have been found alongside pareiasaur Pareiasaurs (meaning "cheek lizards") are an extinct clade of large, herbivorous parareptiles.
