Scaloposauria
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 validi ...

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 pareiasaurs and therapsid Therapsida is a major group of eupelycosaurian synapsids that includes mammals, their ancestors and relatives.

Blattoidealestes
''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. The holotype specimen of ''Blattoidealestes'' was discovered in 1918 in Prince Albert, Western Cape and cataloged as SAM 4321. SAM 4321 consists of a skull and partial postcranial skeleton. At around , the skull is extremely small for a therocephalian. It was heavily distorted during fossilization and preparation, with the right side heavily eroded and most of the skull having been broken off from the main block. The snout is short and the eye sockets are very large. The lower jaw is slender, with a projec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ictidodraco
''Ictidodraco'' is an extinct genus of therocephalian therapsids from the Late Permian of South Africa. The type species ''Ictidodraco longiceps'' was named by South African paleontologists Robert Broom and John T. Robinson in 1948 from the ''Cistecephalus'' Assemblage Zone. ''Ictidodraco'' was once classified as a scaloposaurian in the family Silpholestidae. Scaloposauria and Silpholestidae are no longer regarded as valid groups, and ''Ictidodraco'' is now classified as a basal member of the clade Baurioidea. Description ''Ictidodraco'' is a small therocephalian with a long, pointed snout. It has large orbits or eye sockets that are enclosed by complete postorbital bars at the back margin of the sockets. The temporal openings behind the orbits are relatively small. At the top of the skull, between the two temporal openings, the parietal region is wide. Unlike those of other therocephalians, the parietal does not form a distinctive sagittal crest. As in other advanced therocep ...

Regisaurus
''Regisaurus'' ("Rex's lizard", named after its discoverer 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. Description It was a rather derived baurioid, with a robust skull, short tail, long limbs and relatively large canines. It was apparently related to ''Urumchia'' and like ''Urumchia'', it had vomer bones, which form the secondary palate, but they do not narrow to a tip like in ''Urumchia''. However, it retained some primitive characteristics. It had six incisor teeth in each side of the jaw, whereas other baurioids had less. It was probably carnivorous, and ate insects and small vertebrates Discovery and species ''Regisaurus'' was discovered in 1964 by Francis Rex Parrington and it was named in 1972 by C. H. Mendrez.

Homodontosaurus
''Homodontosaurus'' is an extinct genus of therocephalian therapsids from the Late Permian of South Africa. The type species ''Homodontosaurus kitchingi'' was named by South African paleontologist Robert Broom in 1949. Broom based his description on a small skull found in the ''Cistecephalus'' Assemblage Zone near Graaff-Reinet. The skull is very small, at about long and wide. ''Homodontosaurus'' has large eye sockets and an elongated snout. The lower jaw is long, thin, and curved. Numerous small teeth line the upper jaw and are long, pointed, and round in cross-section. When he first named ''Homodontosaurus'' in 1949, Broom considered it to be a pelycosaur. He noted similarities between the skull of ''Homodontosaurus'' and that of the sphenacodontid ''Secodontosaurus'' from the Early Permian of Texas. Broom thought that ''Homodontosaurus'' was most closely related to a pelycosaur called ''Elliotsmithia'', which he named in 1937 on the basis of the back half of a skull. In 1950 ...

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 parieta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

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.
