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. 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 ...

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'' was around in length, with long limbs and relatively small teeth. It probably ate insects and other small invertebrates. The therocephalians – therapsids with mammal-like heads – were abundant in Permian times, but only a few made it into the Triassic. ''Ericiolacerta'' was one of those. It is possible that they gave rise to the cynodonts, the only therapsid group to survive into post ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedaeosaurus
''Pedaeosaurus'' is an extinct genus of therocephalian therapsids. Fossils have been found from the Fremouw Formation in the southern Transantarctic Mountains of Antarctica.

Therocephalian
Therocephalia is an extinct clade of therapsids (mammals and their close extinct relatives) from the Permian and Triassic periods. The therocephalians ("beast-heads") are named after their large skulls, which, along with the structure of their teeth, suggest that they were carnivores. Like other non-mammalian synapsids, therocephalians were once described as "mammal-like reptiles". Therocephalia is the group most closely related to the cynodonts, which gave rise to the mammals. Indeed, it had been proposed that therocephalians themselves may have given rise to the cynodonts, and therefore that therocephalians as recognised are paraphyletic in relation to cynodonts and so not a clade. Conventionally, however, Therocephalia is regarded as the sister clade of Cynodontia, together forming the clade Eutheriodontia. The close relationship of Therocephalia to Cynodontia takes evidence in a variety of skeletal features. Most notable is that the skull roof is narrowed between two enlarged ...

Silphedosuchus
''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. ''Silphedosuchus'' was found in the Rassypnaya locality of Orenburg Oblast, dating back to the Olenekian stage of the Early Triassic. It was found in a fine-grained sandstone that contains few other vertebrates. This layer was deposited in a large floodplain that covered much of European Russia during the Early Triassic. At the Rassypnaya locality, a lens of coarser sand, presumably deposited by an ancient river, cuts through the finer-grained sandstone. This deposit contains many tetrapods such as temnospondyls and archosauromorphs, but the fossils are part of a different faunal assemblage. The skull is about in length, with a ...

Early Triassic
The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between 251.9 Ma and Ma (million years ago). Rocks from this epoch are collectively known as the Lower Triassic Series, which is a unit in chronostratigraphy. The Early Triassic is the oldest epoch of the Mesozoic Era. It is preceded by the Lopingian Epoch (late Permian, Paleozoic Era) and followed by the Middle Triassic Epoch. The Early Triassic is divided into the Induan and Olenekian ages. The Induan is subdivided into the Griesbachian and Dienerian subages and the Olenekian is subdivided into the Smithian and Spathian subages. The Lower Triassic series is coeval with the Scythian Stage, which is today not included in the official timescales but can be found in older literature. In Europe, most of the Lower Triassic is composed of Buntsandstein, a lithostratigraphic unit of continental red beds. The Early Triassic and partly also the Middle Trias ...
