Microgomphodon
''Microgomphodon'' is an extinct genus of therocephalian therapsid from the Middle Triassic of South Africa and Namibia. Currently only one species of ''Microgomphodon'', ''M. oligocynus'', is recognized. With fossils present in the ''Cynognathus'' Assemblage Zone (CAZ) of the Burgersdorp Formation in South Africa and Omingonde Formation of Namibia and ranging in age from late Olenekian to Anisian, it is one of the most geographically and temporally widespread therocephalian species. Moreover, its occurrence in the upper Omigonde Formation of Namibia makes ''Microgomphodon'' the latest-surviving therocephalian. ''Microgomphodon'' is a member of the family Bauriidae and a close relative of ''Bauria'', another South African bauriid from the CAZ. Like other bauriids, it possesses several mammal-like features such as a secondary palate and broad, molar-like postcanine teeth, all of which evolved independently from mammals.

Bauriids
Bauriidae is an extinct family of therocephalian therapsids. Bauriids were the latest-surviving group of therocephalians after the Permian–Triassic extinction event, going extinct in the Middle Triassic. They are among the most advanced eutherocephalians and possess several mammal-like features such as a secondary palate and wide postcanine teeth at the back of the jaws (analogous to mammalian molars). Unlike other therocephalians, bauriids were herbivorous. They were also smaller than earlier members of the group. Two subfamilies are classified within Bauriidae: Nothogomphodontinae and Bauriinae. Description Bauriids have a dentition characteristic of herbivores with the exception of ''Nothogomphodon''. There are four incisors on either side of the upper jaw. Like other therocephalians, bauriids have moderately enlarged canines. The postcanine teeth behind the canines are broad. The postcanines of the upper and lower jaw fit tightly together as an adaptation to processing plant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bauria
''Bauria'' is an extinct genus of the suborder Therocephalia that existed during the Early and MiddleTriassic period, around 246-251 million years ago. It belonged to the family Bauriidae. ''Bauria'' was probably a carnivore or insectivore. It lived in South Africa, specifically in the Burgersdorp Formation in South Africa. ''Bauria'' was named by Robert Broom in 1909 and found at Winnaarsbaken, South Africa. The first species Broom discovered, ''Bauria cynops'', was a reasonably complete skull, but according to the first description somewhat poorly preserved, and apparently equally poorly prepared. Five other specimens were later found at different points in time, with mostly skulls being found. Only two species of ''Bauria'' are known, with the most recent one, ''Bauria robusta'', being discovered by J. W. Kitching in 1955 in the Burghersdorp district However, a 2013 study proposed that '' Microgomphodon oligocynus'' and ''Bauria cynops'' are recognized as the only vali ...

Therocephalia
Therocephalia is an extinct suborder of eutheriodont therapsids (mammals and their close relatives) from the Permian and Triassic. 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. This relationship takes evidence in a variety of skeletal features. The fossils of therocephalians are numerous in the Karoo of South Africa, but have also been found in Russia, China, Tanzania, Zambia, and Antarctica. Early therocephalian fossils discovered in Middle Permian deposits of South Africa support a Gondwanan origin for the group, which seems to have spread quickly across Earth. Although almost every therocephalian lineage ended during the great Permian–Triassic extinction event, a few represe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cynognathus Assemblage Zone
The ''Cynognathus'' Assemblage Zone is a tetrapod biozone utilized in the Karoo Basin of South Africa. It is equivalent to the Burgersdorp Formation, the youngest lithostratigraphic formation in the Beaufort Group, which is part of the fossiliferous and geologically important Karoo Supergroup. The '' Cynognathus'' Assemblage Zone is the youngest of the eight biozones found in the Beaufort Group, and is considered to be late Early Triassic (Olenekian) to early Middle Triassic (Anisian) in age (around 247 Ma). The name of the biozone refers to '' Cynognathus crateronotus'', a large and carnivorous cynodont therapsid which occurs throughout the entire biozone. History The first fossils to be found in the Beaufort Group rocks that encompass the current eight biozones were discovered by Andrew Geddes Bain in 1856. However, it was not until 1892 that it was observed that the geological strata of the Beaufort Group could be differentiated based on their fossil taxa. The initial undert ...

Middle Triassic
In the geologic timescale, the Middle Triassic is the second of three epochs of the Triassic period or the middle of three series in which the Triassic system is divided in chronostratigraphy. The Middle Triassic spans the time between Ma and Ma (million years ago). It is preceded by the Early Triassic Epoch and followed by the Late Triassic Epoch. The Middle Triassic is divided into the Anisian and Ladinian ages or stages. Formerly the middle series in the Triassic was also known as Muschelkalk. This name is now only used for a specific unit of rock strata with approximately Middle Triassic age, found in western Europe. Middle Triassic fauna Following the Permian–Triassic extinction event, the most devastating of all mass-extinctions, life recovered slowly. In the Middle Triassic, many groups of organisms reached higher diversity again, such as the marine reptiles (e.g. ichthyosaurs, sauropterygians, thallatosaurs), ray-finned fish and many invertebrate groups like ...

Karoo Basin
The Karoo Supergroup is the most widespread stratigraphy, stratigraphic unit in Africa south of the Kalahari Desert. The group (stratigraphy), supergroup consists of a sequence of units, mostly of nonmarine origin, deposited between the Pennsylvanian (geology), Late Carboniferous and Early Jurassic, a period of about 120 million years. In southern Africa, rocks of the Karoo Supergroup cover almost two thirds of the present land surface, including all of Lesotho, almost the whole of Free State (province), Free State, and large parts of the Eastern Cape, Northern Cape, Mpumalanga and KwaZulu-Natal Provinces of South Africa. Karoo supergroup outcrops are also found in Namibia, Eswatini, Zambia, Zimbabwe and Malawi, as well as on other continents that were part of Gondwana. The basins in which it was deposited formed during the formation and breakup of Pangea.McCarthy, T., Rubridge, B. (2005). ''The Story of Earth and Life.'' pp. 161, 187–241.

Lesotho
Lesotho ( ), officially the Kingdom of Lesotho, is a country landlocked country, landlocked as an Enclave and exclave, enclave in South Africa. It is situated in the Maloti Mountains and contains the Thabana Ntlenyana, highest mountains in Southern Africa. It has an area of over and has a population of about million. It was previously the British Crown colony of Basutoland, which declared independence from the United Kingdom on 4 October 1966. It is a fully sovereign state and is a member of the United Nations, the Commonwealth of Nations, the African Union, and the Southern African Development Community. The name ''Lesotho'' roughly translates to "land of the Sotho". History Basutoland Basutoland emerged as a single body politic, polity under King Moshoeshoe I in 1822. Moshoeshoe, a son of Mokhachane, a minor tribal chief, chief of the Bakoteli lineage, formed his own clan and became a chief around 1804. Between 1820 and 1823, he and his followers settled at the Buth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free State (province)
The Free State, known as Orange Free State until the 28th of June 1995 when its name was changed, is a province of South Africa. Its capital is Bloemfontein, which is also South Africa's judicial capital. Its historical origins lie in the Boer republic called the Orange Free State and later Orange Free State Province. History The current borders of the province date from 1994 when the Bantustans were abolished and reincorporated into South Africa. It is also the only one of the four original provinces of South Africa not to undergo border changes, apart from the reincorporation of Bantustans, and its borders date from before the outbreak of the Boer War. Law and government The provincial government consists of a premier, an executive council of ten ministers, and a legislature. The provincial assembly and premier are elected for five-year terms, or until the next national election. Political parties are awarded assembly seats based on the percentage of votes each party receive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
