Cistecephalus Microrhinus
''Cistecephalus'' is an extinct genus of dicynodont therapsid from the Late Permian of southern Africa (South Africa and Zambia). It was a small, specialised, burrowing dicynodont, possibly with habits similar to a modern mole. The head was flattened and wedge-shaped, the body long, and the forelimbs very strong, with similarities in structure to the forelimb of modern burrowing mammals. It was one of the first genera of dicynodonts to be described, by Richard Owen, in 1876. ''Cistecephalus'' could reach up to in length. Description ''Cistecephalus'' was one of the most atypical dicynodont genera. However, it was broadly similar in anatomy to other cistecephalids, all of which share similar adaptations to digging. Its skull was broad, with laterally-directed temporal openings and a sharply tapering snout, similar to extant fossorial animals. However, it has relatively large, anteriorly-directed orbits, suggesting binocular vision. It had a short neck and laterally-directed sho ...

Wuchiapingian
In the geologic timescale, the Wuchiapingian or Wujiapingian (from in the Liangshan area of Hanzhong, Shaanxi Province) is an age or stage of the Permian. It is also the lower or earlier of two subdivisions of the Lopingian Epoch or Series. The Wuchiapingian spans the time between and million years ago (Ma). It was preceded by the Capitanian and followed by the Changhsingian. Regional stages with which the Wuchiapingian is coeval or overlaps include the Djulfian or Dzhulfian, Longtanian, Rustlerian, Saladoan, and Castilian. Stratigraphic definitions The Wuchiapingian was first used in 1962, when the Lopingian Series of southwestern China was divided in the Changhsingian and Wuchiapingian Formations. In 1973 the Wuchiapingian was first used as a chronostratigraphic unit (i.e. a stage, as opposed to a formation, which is a lithostratigraphic unit). The base of the Wuchiapingian Stage is defined as the place in the stratigraphic record where the conodont species ''Clarkina po ...

Dicynodon
''Dicynodon'' ("two dog-teeth") is a genus of dicynodont therapsid that flourished during the Upper Permian period. Like all dicynodonts, it was herbivorous animal. This reptile was toothless, except for prominent tusks, hence the name. It probably cropped vegetation with a horny beak, much like a tortoise, while the tusks may have been used for digging up roots and tubers. Many species of ''Dicynodon'' have been named, and the genus is considered a wastebasket taxon. A 2011 study of the genus found most of the species to represent a paraphyletic grouping, with the only valid members of ''Dicynodon'' being ''D. lacerticeps'' and ''D. huenei''. A 2019 study named a new species ''D. angielczyki'', but simultaneously transferred ''D. huenei'' to the genus ''Daptocephalus''. Description ''Dicynodon'' was a medium-sized and advanced member of the Dicynodont group. It had an average length of , although size differed among species. Its fossil remains have been found in sediments of l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robertia
''Robertia'' is an extinct genus of small herbivorous dicynodonts from the Middle to Late Permian of South Africa, between 260 and 265 million years ago. It is a monospecific genus, consisting of the type-species ''R. broomiana,'' which was classified by Lieuwe Dirk Boonstra in 1948 and named in honor of Robert Broom for his study of South African mammal-like reptiles. ''Robertia'' had characteristic caniniform tusks and few, small teeth on the maxillary and dentary table. Its beak and the propalinal movement of the jaw, as with other dicynodonts, allowed for efficient cutting of plant matter. The solid, barrel-bodied creatures had a sprawling stance with a flexible backbone, which likely gave them a lizard-like appearance as they moved.King, G. (1981).

Eosimops
''Eosimops'' is an extinct genus of pylaecephalid dicynodonts. They were small synapsids superficially resembling modern mammals. ''Eosimops'' is known from several skull specimens, as well as one complete skeleton. ''Eosimops'' lived during the Middle Permian of South Africa. Etymology ''Eosimops'' was named in by South African paleontologist Robert Broom. Its name is derived from the Ancient Greek ''Ēṓs'' (“dawn”) and ''ópsis'' (“appearance”). Discovery ''Eosimops'' was discovered in 1921 by Robert Broom, based on a single skull. It was found in the ''Tapinocephalus'' Assemblage Zone strata of South Africa, an area which provides a rich variety of early therapsids and covers a period of almost 100 million years ranging from the Permian to the Jurassic. Later, other skull specimens as well as a complete skeleton were found. ''Eosimops'' is found above the stratigraphic range of the early dicynodont '' Eodycynodon''. Also found in the ''Pristerognathus'' Assem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diictodon
''Diictodon'' is an extinct genus of pylaecephalid dicynodont. These mammal-like synapsids lived during the Late Permian period, approximately 255 million years ago. Fossils have been found in the ''Cistecephalus'' Assemblage Zone of the Madumabisa Mudstone of the Luangwa Basin in Zambia and the ''Tropidostoma'' Assemblage Zone of the Teekloof Formation, ''Tapinocephalus'' Assemblage Zone of the Abrahamskraal Formation, ''Dicynodon'' Assemblage Zone of the Balfour Formation, ''Cistecephalus'' Assemblage Zone of the Middleton or Balfour Formation of South Africa and the Guodikeng Formation of China. Roughly half of all Permian vertebrate specimens found in South Africa are those of ''Diictodon''. This small herbivorous animal was one of the most successful synapsids in the Permian period. Characteristics Appearance ''Diictodon'' had disproportionally large heads that ended in a horny beak. Both males and females had a pair of tusks sticking out from the upper jaw, ...

Pylaecephalidae
Pylaecephalidae is a family of dicynodont therapsids that includes ''Diictodon'', ''Robertia'', and ''Prosictodon'' from the Permian of South Africa. Pylaecephalids were small burrowing dicynodonts with long tusks. The family was first named in 1934 and was redefined in 2009.

Cistecephalidae
Cistecephalidae is an extinct family (biology), family of dicynodont therapsids from the Late Permian of South Africa, India and Zambia. It includes the genera ''Cistecephalus'', ''Cistecephaloides'', and ''Kawingasaurus''. Cistecephalids are thought to have had a fossorial or burrowing lifestyle, with adaptations such as broad skulls, strong forelimbs, and squat bodies. A similar group of dicynodonts called the pylaecephalids were also fossorial, although to a lesser extent than cistecephalids. Cistecephalids showed a high level of endemism, with each of the five known species unique to a single region. Description Cistecephalids were small dicynodonts. Most species, with the exception of ''Kembawacela'', lacked tusks, but sexually dimorphic supraorbital ridges were present. Cistecephalids had boxy, broad skulls with relatively laterally directed temporal openings, a result of a considerably broadened intertemporal region. ''Sauroscaptor'', the most basal genus of the family, h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert Broom
Robert Broom FRS FRSE (30 November 1866 6 April 1951) was a British- South African doctor and palaeontologist. He qualified as a medical practitioner in 1895 and received his DSc in 1905 from the University of Glasgow. From 1903 to 1910, he was professor of zoology and geology at Victoria College, Stellenbosch, South Africa, and subsequently he became keeper of vertebrate palaeontology at the South African Museum, Cape Town. Life Broom was born at 66 Back Sneddon Street in Paisley, Renfrewshire, Scotland, the son of John Broom, a designer of calico prints and Paisley shawls, and Agnes Hunter Shearer. In 1893, he married Mary Baird Baillie, his childhood sweetheart. In his medical studies at the University of Glasgow Broom specialised in obstetrics. After graduating in 1895 he travelled to Australia, supporting himself by practising medicine. He settled in South Africa in 1897, just prior to the South African War. From 1903 to 1910, he was professor of Zoology and Geolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
