Paraburnetia DB
''Paraburnetia'' is an extinct genus of biarmosuchian therapsids from the Late Permian of South Africa. It is known for its species ''P. sneeubergensis'' and belongs to the family Burnetiidae. ''Paraburnetia'' lived just before the Permian–Triassic mass extinction event. The etymology of ''Paraburnetia sneeubergensis'' comes from ''para'', meaning beside or near; '' Burnetia'' indicating the first named member of the clade; and ''sneeubergensis'' for the location the Sneeuberge mountains above where the specimen was found. ''P. sneeubergensis'' is known by its knobby skull, which is a shared synapomorphy with ''B. mirabilis'' and ''P. viatkensis'' They are synapsids, from which, their clade of therapsids is derived from.Rubidge, B., & Sidor, C.

Hipposaurus
''Hipposaurus'' ('horse lizard') is an extinct genus of basal therapsids known from the ''Tapinocephalus'' Assemblage Zone of the Main Karoo Basin, South Africa. Chronologically this is within the Capitanian stage of the Guadalupian Series (Middle Permian). The genus was first described by S.H. Haughton as ''H. boonstrai'' on the basis of a skull and associated skeleton and was later considered a gorgonopsian in the family 'Ictidorhinidae' by Robert Broom. It is now considered a basal biarmosuchian, but its affinities remain uncertain. ''H.boonstrai'' is currently known from only two specimens in the Iziko South African Museum, Cape Town. "''H.brinki''" is based on a single skull that was described by D. Sigogneau in 1970;Sigogneau, D. 1970. Révision systématique des gorgonopsiens Sud Arficains.

Biarmosuchus
''Biarmosuchus'' is an extinct genus of biarmosuchian therapsids that lived around 267 mya during the Middle Permian period. ''Biarmosuchus'' was discovered in the Perm region of Russia. The first specimen was found in channel sandstone that was deposited by flood waters originating from the young Ural Mountains. Description ''Biarmosuchus'' was a medium-sized predator, similar in size to a large dog, grew up to 1.5–2 m in length with a skull length 15 cm (immature) to 21 cm. It was a lightly built, probably agile animal that would have fed on smaller tetrapods. Their legs are quite long, and the animals were probably quite agile in spite of their size. A large opening for the eye and a small temple opening common in primitive stem-mammals, this lends to a weak bite but how it ate is pure speculation. The teeth contained eight small incisors on the palate, followed by a canine tooth and a further five canine teeth. So together the species contained fourteen upper ...

Biarmosuchian
Biarmosuchians are an extinct clade of non-mammalian synapsids from the Permian. They are the most basal group of the therapsids. All of them were moderately-sized, lightly-built carnivores, intermediate in form between basal sphenacodont "pelycosaurs" and more advanced therapsids. Biarmosuchians were rare components of Permian ecosystems, and the majority of species belong to the clade Burnetiamorpha, which are characterized by elaborate cranial ornamentation. Characteristics The biarmosuchian skull is very similar to the sphenacodontid skull, differing only in the larger temporal fenestra (although these are still small relative to later therapsids), slightly backward-sloping occiput (the reverse of the pelycosaur condition), reduced number of teeth, and single large canine teeth in both upper and lower jaws, and other features (Carroll 1988 pp. 370, Benton 2000 p. 114). In later specialised Biarmosuchia, these resemble the enlarged canines of the Gorgonopsia. The pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burnetiamorpha
Burnetiamorpha is a clade of biarmosuchian therapsids. Burnetiamorphs are the most derived biarmosuchians. The name Burnetiamorpha has been in use since South African paleontologist Robert Broom erected the group in 1923, but it has recently been put to use in phylogenetic classification as a clade including Burnetiidae and its closest relatives, including ''Lemurosaurus'', ''Lophorhinus'', and '' Lobalopex''.

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 '' Clarkin ...

Hill At Karoo National Park
A hill is a landform that extends above the surrounding terrain. It often has a distinct summit. Terminology The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as steep as a mountain. Geographers historically regarded mountains as hills greater than above sea level, which formed the basis of the plot of the 1995 film ''The Englishman who Went up a Hill but Came down a Mountain''. In contrast, hillwalkers have tended to regard mountains as peaks above sea level. The ''Oxford English Dictionary'' also suggests a limit of and Whittow states "Some authorities regard eminences above as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least high, while the official UK government's definition of a mountain is a summit of or higher. Some definitions include a topographical prominence requirement, typically or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pangea
Pangaea or Pangea () was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from the earlier continental units of Gondwana, Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ago, at the end of the Triassic and beginning of the Jurassic. In contrast to the present Earth and its distribution of continental mass, Pangaea was centred on the equator and surrounded by the superocean Panthalassa and the Paleo-Tethys and subsequent Tethys Oceans. Pangaea is the most recent supercontinent to have existed and the first to be reconstructed by geologists. Origin of the concept The name "Pangaea" is derived from Ancient Greek ''pan'' (, "all, entire, whole") and ''Gaia'' or Gaea (, "Mother Earth, land"). The concept that the continents once formed a contiguous land mass was hypothesised, with corroborating evidence, by Alfred Wegener, the originator of t ...

Cistecephalus Assemblage Zone
The ''Cistecephalus'' Assemblage Zone is a tetrapod assemblage zone or biozone found in the Adelaide Subgroup of the Beaufort Group, a majorly fossiliferous and geologically important geological group of the Karoo Supergroup in South Africa. This biozone has outcrops located in the Teekloof Formation north-west of Beaufort West in the Western Cape, in the upper Middleton Formation, Middleton and lower Balfour Formations respectively from Colesberg of the Northern Cape to east of Graaff-Reinet in the Eastern Cape. The ''Cistecephalus'' Assemblage Zone is one of eight biozones found in the Beaufort Group, and is considered to be Late Permian in age. The name of the biozone refers to ''Cistecephalus'', a small, burrowing dicynodont therapsid. It is characterized by the presence of this species, known especially from the upper sections of this biozone, and the first appearance of the dicynodont ''Aulacephalodon''.

Dicynodontia
Dicynodontia is an extinct clade of anomodonts, an extinct type of non-mammalian therapsid. Dicynodonts were herbivorous animals with a pair of tusks, hence their name, which means 'two dog tooth'. Members of the group possessed a horny, typically toothless beak, unique amongst all synapsids. Dicynodonts first appeared in Southern Pangaea during the mid-Permian, ca. 270–260 million years ago, and became globally distributed and the dominant herbivorous animals in the Late Permian, ca. 260–252 Mya. They were devastated by the end-Permian Extinction that wiped out most other therapsids ca. 252 Mya. They rebounded during the Triassic but died out towards the end of that period. They were the most successful and diverse of the non-mammalian therapsids, with over 70 genera known, varying from rat-sized burrowers to elephant-sized browsers. Characteristics The dicynodont skull is highly specialised, light but strong, with the synapsid temporal openings at the rear of the skul ...
