Baurioids
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. 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 analyses of scaloposaurian taxa. The val ...

Polycynodon
''Polycynodon'' is an extinct genus of therocephalians from the Late Permian of South Africa. It is known from the ''Cistecephalus'' Assemblage Zone. The type species was first described as ''Octocynodon elegans'' by South African paleontologist Robert Broom in 1940, but the name ''Octocynodon'' was preoccupied by a genus of labrid fish first described in 1904. Along with John T. Robinson, Broom instated ''Polycynodon'' as a replacement name for ''O. elegans'' in 1948. ''Polycynodon'' is classified in Baurioidea 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. ..., although its relationship to other baurioid therocephalians is uncertain.

Yikezhaogia
''Yikezhaogia'' is an extinct genus of therocephalian therapsids from the Early Triassic of Mongolia. It is known from a single fragmentary skull and associated postcranial bones representing the species ''Yikezhaogia megafenestrala''. It is identifiable as a therocephalian by its thin postorbital bar behind the eye socket, its elongated temporal opening behind the bar, and a thin lower jaw with a low coronoid process. Large tooth sockets in the upper jaw indicate that ''Yikezhaogia'' had large caniniform teeth. The teeth of the lower jaw are blunt-tipped and cylindrical. Although its exact position among therocephalians is uncertain, ''Yikezhaogia'' is probably a basal member of the group Baurioidea 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. ....

Silphictidoides
''Silphictidoides'' is an extinct genus of therocephalian therapsids from the Late Permian of Tanzania. The type species ''Silphictidoides ruhuhuensis'' was named by German paleontologist Friedrich von Huene in 1950 from the ''Tropidostoma'' Assemblage Zone. ''Silphictidoides'' was once classified within the family Silpholestidae. Silphedolestids are no longer recognized as a valid grouping, and ''Silphictidoides'' is now considered a basal member of the clade Baurioidea Baurioidea is a superfamily of therocephalian therapsids.

Scaloposaurus
''Scaloposaurus'' is an extinct genus of carnivorous therocephalians living during the Permian 259.0—254.0 Ma existing for approximately . Taxonomy ''Scaloposaurus'' was named by Owen (1876).

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, and was the first scaloposaurid found in Russia (scaloposaurids are also known from southern Africa and Antarctica). More recent studies of therocephalians have found scaloposaurids like ''Scalopodon'' to be juvenile forms of larger therocephal ...

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. Scaloposauridae is no longer recognized as a valid group, and ''Scalopocephalus'' is now classified as a basal member of Baurioidea Baurioidea is a superfamily of therocephalian therapsids.

Macroscelesaurus
''Macroscelesaurus'' is an extinct genus of therocephalian therapsid from the Late Permian of South Africa. The type species ''Macroscelesaurus janseni'' was named by Sidney H. Haughton in 1918 from the ''Cistecephalus'' Assemblage Zone. It is one of the few therocephalians known from postcranial remains. Description and history ''Macroscelesaurus'' is known from a single holotype consisting of the mold of a partial skeleton. The impression was found on a sandstone block that made up the wall of a kraal or sheep enclosure near the town of Victoria West. It includes most of the postcranial skeleton, including the vertebral column, ribs, limbs, and the pelvic and pectoral girdles. Most of the skull is not preserved. The skeleton is preserved in ventral view, with the body curving to the right and the limbs bent to one side. The specimen was brought to South African paleontologist Sidney H. Haughton, and formally described the next year. On the basis of the impression, Haughton des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
