Diictodon Galeops And Procynosuchus Delaharpae Models
''Diictodon'' (meaning "two weasel teeth") is an extinct genus of pylaecephalid dicynodont that 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. ‘There is a clear distinction between specimens having canine tusks an ...

Capitanian
In the geologic timescale, the Capitanian is an age or stage of the Permian. It is also the uppermost or latest of three subdivisions of the Guadalupian Epoch or Series. The Capitanian lasted between and million years ago. It was preceded by the Wordian and followed by the Wuchiapingian.; 2004: ''A Geologic Time Scale 2004'', Cambridge University Press A significant mass extinction event occurred at the end of this stage, which was associated with anoxia and acidification in the oceans and possibly caused by the volcanic eruptions that produced the Emeishan Traps. This extinction event may be related to the much larger Permian–Triassic extinction event that followed about 10 million years later. Stratigraphy The Capitanian Stage was introduced into scientific literature by George Burr Richardson in 1904. The name comes from the Capitan Reef in the Guadalupe Mountains (Texas, United States). The Capitanian was first used as a stratigraphic subdivision of the Guadalupi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abrahamskraal Formation
The Abrahamskraal Formation is a geological formation and is found in numerous localities in the Northern Cape, Western Cape, and the Eastern Cape of South Africa. It is the lowermost formation of the Adelaide Subgroup of the Beaufort Group, a major geological group that forms part of the greater Karoo Supergroup. It represents the first fully terrestrial geological deposits of the Karoo Supergroup, Karoo Basin. Outcrops of the Abrahamskraal Formation are found from the small town Middelpos in its westernmost localities, then around Sutherland, Northern Cape, Sutherland, the Moordenaarskaroo north of Laingsburg, Western Cape, Laingsburg, Williston, Northern Cape, Williston, Fraserburg, Leeu-Gamka, Loxton, Northern Cape, Loxton, and Victoria West in the Western Cape and Northern Cape. In the Eastern Cape outcrops are known from Rietbron, north of Klipplaat and Grahamstown, and also southwest of East London, Eastern Cape, East London.

Cladogram
A cladogram (from Greek language, Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an Phylogenetic tree, evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be consistent with the same cladogram. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other e ...

Pangaea
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 period 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. Pangaea was C-shaped, with the bulk of its mass stretching between Earth's northern and southern polar regions and surrounded by the superocean Panthalassa and the Paleo-Tethys and subsequent Tethys Oceans. Pangaea is the most recent supercontinent to have existed and was 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 first to suggest that the continents were once joined and later separated may have been Abraham Ortelius in 1596. The concept that the c ...

Iziko Museums of South Africa, formerly Southern Flagship Institution (SFI) and then Iziko Museums of Cape Town, is an organisation governing national museums in greater Cape Town, in the Western Cape province of South Africa. there are 11 museums in the group. History In 1998, five national museums in the Western Cape (the South African Cultural History Museum, South African Museum, South African National Gallery, the William Fehr Collection (at the Castle of Good Hope), and the Michaelis Collection) were amalgamated as the Southern Flagship Institution (SFI).
