Bradysaurus
''Bradysaurus'' is a genus of large, primitive and widespread pareiasaur. They possessed a covering of armoured scutes, likely serving as defense against their main predators, the gorgonopsians. Fossils of ''Bradysaurus'' are known from the ''Tapinocephalus'' Tapinocephalus Assemblage Zone, Assemblage Zone (Capitanian age) of the South African Karoo. Along with the similarly large dinocephalia, the bradysaurs constituted the herbivore, herbivorous megafauna of the late Guadalupian, Middle Permian Period (geology), Period. Description ''Bradysaurus'' was in length and half a tonne to a tonne in weight. The skull was large (about 42 to 48 centimeters long), broad and rounded at the front. It was coarsely sculptured and knobby, with the suture (anatomical), sutures between the bones not clearly visible. The marginal teeth were high-crowned, with only a few cusps, which is a primitive characteristic. The feet were short and broad, the phalanges, phalangeal count being 2,3, ...

Tapinocephalus Assemblage Zone
The ''Tapinocephalus'' Assemblage Zone is a tetrapod assemblage zone or biozone which correlates to the middle Abrahamskraal Formation, Adelaide Subgroup of the Beaufort Group, a fossiliferous and geologically important geological Group of the Karoo Supergroup in South Africa. The thickest outcrops, reaching approximately , occur from Merweville and Leeu-Gamka in its southernmost exposures, from Sutherland through to Beaufort West where outcrops start to only be found in the south-east, north of Oudshoorn and Willowmore, reaching up to areas south of Graaff-Reinet. Its northernmost exposures occur around the towns Fraserburg and Victoria West. The ''Tapinocephalus Assemblage Zone'' is the second biozone of the Beaufort Group. The name of the biozone refers to '' Tapinocephalus atherstonei'', a large herbivorous tapinocephalid dinocephalian therapsid. It is characterised by the presence of this dinocephalian species along with the appearance of other advanced tapino ...

Pareiasauria
Pareiasaurs (meaning "cheek lizards") are an extinct clade of large, herbivorous parareptiles. Members of the group were armoured with osteoderms which covered large areas of the body. They first appeared in southern Pangea during the Middle Permian, before becoming globally distributed during the Late Permian. Pareiasaurs were the largest reptiles of the Permian, some reaching sizes over , equivalent to the largest contemporary therapsids. Pareiasaurs became extinct in the end-Permian mass extinction event. Description Pareiasaurs ranged in size from long, with some species estimated to exceed in body mass. The limbs of many parieasaurs were extremely robust, likely to account for the increased stress on their limbs caused by their typically sprawling posture. The cow-sized '' Bunostegos'' differed from other pareiasaurs by having a more upright limb posture, being amongst the first amniotes to develop this trait. Pareiasaurs were protected by bony scutes called osteoderms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Embrithosaurus
''Embrithosaurus'' was a pareiasaur from the Permian of South Africa. Description ''Embrithosaurus'' was in length and in weight. The skull is relatively deep and narrow. The body is lightly armoured with thin, smooth dermal scutes. Species * ''E. schwarzi'' (Watson, 1914). The type species. This is the most advanced species of this genus, as indicated by the teeth, which have nine cusps (in three groups of three). In cladistic analyses it is used as the monotypal species for the genus. * ''E. alexanderi'' (Haughton and Boonstra, 1929). This species was made the type for ''"Dolichopareia"''. As the name indicates, the skull is long and narrow. This would seem to indicate a different lifestyle or diet to other parieasaurs. More recently, it has been used as the monotypal species for the genus ''Nochelesaurus'' (it is not clear what the status of ''Embrithosaurus strubeni'' is, this may be a further transitional species). In cladistic analyses, this species is phylogenetically in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Karoo
The Karoo ( ; from the Afrikaans borrowing of the South Khoekhoe Khoemana (also known as !Orakobab or Korana) word is a semidesert natural region of South Africa. No exact definition of what constitutes the Karoo is available, so its extent is also not precisely defined. The Karoo is partly defined by its topography, Karoo Supergroup, geology and climate, and above all, its low rainfall, arid air, cloudless skies, and extremes of heat and cold. The Karoo also hosted a well-preserved ecosystem hundreds of millions of years ago which is now represented by many fossils. The Karoo formed an almost impenetrable barrier to the interior from Cape Town, and the early adventurers, explorers, hunters, and travelers on the way to the Highveld unanimously denounced it as a frightening place of great heat, great frosts, great floods, and great droughts. Today, it is still a place of great heat and frosts, and an annual rainfall of between 50 and 250 mm, though on some of the mountains i ...

Field Museum
The Field Museum of Natural History (FMNH), also known as The Field Museum, is a natural history museum in Chicago, Illinois, and is one of the largest such museums in the world. The museum is popular for the size and quality of its educational and scientific programs, and its extensive scientific specimen and artifact collections. The permanent exhibitions, which attract up to 2 million visitors annually, include fossils, current cultures from around the world, and interactive programming demonstrating today's urgent conservation needs. The museum is named in honor of its first major benefactor, Marshall Field, the department-store magnate. The museum and its collections originated from the 1893 World's Columbian Exposition and the artifacts displayed at the fair. The museum maintains a temporary exhibition program of traveling shows as well as in-house produced topical exhibitions. The professional staff maintains collections of over 24 million specimens and objects ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Dougal Dixon
Dougal Dixon (born 1 March 1947) is a Scottish geologist, palaeontologist, educator and author. Dixon has written well over a hundred books on geology and palaeontology, many of them for children, which have been credited with attracting many to the study of the prehistoric animals. Because of his work as a prolific science writer, he has also served as a consultant on dinosaur programmes. Dixon is most famous for his 1980/90s trilogy of speculative evolution books: ''After Man'' (1981), '' The New Dinosaurs'' (1988) and '' Man After Man'' (1990). These books use imagined future and alternate animals to explain various natural processes, including evolution, natural selection, zoogeography and climate change. Early life and education Dixon was born in Dumfries on 1 March 1947 to parents Thomas Bell Dixon and Margaret Ann Hurst. He had an older brother, John Edward, who died in 1942 at the age of six.

Scutosaurus
''Scutosaurus'' ("shield lizard") is an extinct genus of pareiasaur parareptiles. Its genus name refers to large plates of armor scattered across its body. It was a large anapsid reptile that, unlike most reptiles, held its legs underneath its body to support its great weight. Fossils have been found in the Sokolki Assemblage Zone of the Malokinelskaya Formation in European Russia, close to the Ural Mountains, dating to the late Permian (Lopingian) between 264 and 252 million years ago. Research history The first fossils were uncovered by Russian paleontologist Vladimir Prokhorovich Amalitskii while documenting plant and animal species in the Upper Permian sediments in the Northern Dvina River, Arkhangelsk Oblast, Arkhangelsk District, Northern European Russia. Amalitskii had discovered the site in 1899, and he and his wife Anne Amalitskii continued to oversee excavation until 1914, recovering numerous nearly complete and articulated (in their natural position) skeletons belon ...
