Vjushkovia
''Garjainia'' is an extinct genus of erythrosuchid archosauriform reptile from the Olenekian of Russia and South Africa. It was approximately 1.50–2 m (5–6 ft 8 in) long. It contained two species, ''Garjainia prima'' from the Yarengian/Yarkenskian Supergorizont of Russia, and ''Garjainia madiba'' from the Burgersdorp Formation ( ''Cynognathus'' Assemblage Zone A) of South Africa. "''Vjuskovia triplicostata''", a name assigned to some erythrosuchid fossils from Russia, has been synonymized with ''Garjainia prima''. Discovery ''Garjainia prima'' was first discovered in a small village in Russia by a farmer. The exact date of the discovery is not known but its believed to have been found some time in the early 1950s. An later find is ''G. madiba'', which was found in South Africa in the 1960s. In the same locality another much larger erythrosuchid was also found, called '' Erythrosuchus africanus'', which was the one of the largest terrestrial predators of the Early Tria ...

Shansisuchus
''Shansisuchus'' (meaning "Shansi Province crocodile") is an extinct genus of archosauriform reptile belonging to the family Erythrosuchidae that lived during the Middle Triassic in what is now China. The first fossils of ''Shansisuchus'' were discovered from the Ermaying Formation of Shansi Province in 1964 by Chinese paleontologist Yang Zhongjian. Like other erythrosuchids, ''Shansisuchus'' was a large-bodied carnivore with a large, deep skull. ''Shansisuchus'' is unique among early archosauriforms in having a hole in its skull called a subnarial fenestra. Description ''Shansisuchus'' is a large erythrosuchid distinguished from other members of the group by two characters: a tongue-and-groove articulation between the premaxilla and nasal bones of the skull and the presence of a subnarial fenestra. In ''Shansisuchus'' the premaxilla, a bone that makes up the front of the snout, projects backward and fits into a groove in the nasal, a bone that makes up the top of the snout. T ...

Erythrosuchids
Erythrosuchidae (meaning "red crocodiles" in Greek) are a family of large basal archosauriform carnivores that lived from the later Early Triassic (Olenekian) to the early Middle Triassic (Anisian). Naming The family Erythrosuchidae was named by David Meredith Seares Watson in 1917.D.M.S. Watson. 1917. "A sketch classification of the Pre-Jurassic tetrapod vertebrates". ''Proceedings of the Zoological Society of London'' 1917: 167–186 Description They were the apex predators of their day, with lengths of to almost . Their fossil remains are known to date from South Africa (Beaufort Group of the Karoo Basin), China, India and European Russia, from the Early to Middle Triassic. Erythrosuchids were unusually large and robust archosauromorphs. Several features set them apart from other archosauriformes and are also seen in later, more derived archosaurs. For example, they lack teeth on the palate, which are found in other early archosauriformes, such as ''Doswellia'' and eupark ...

Proterosuchus
''Proterosuchus'' is an extinct genus of archosauriform reptiles that lived during the Early Triassic. It contains three valid species: the type species ''P. fergusi'' and the referred species ''P. alexanderi'' and ''P. goweri''. All three species lived in what is now South Africa. The genus was named in 1903 by the South African paleontologist Robert Broom. The well-known genus ''Chasmatosaurus'' is a junior synonym of ''Proterosuchus''. ''Proterosuchus'' was a mid-sized quadrupedal reptile with a sprawling stance that could reach a length of up to . It had a large head and distinctively hooked snout. It was a predator, which may have hunted prey such as ''Lystrosaurus''. The lifestyle of ''Proterosuchus'' remains debated; it may have been terrestrial or it may have been a semiaquatic ambush predator similar to modern crocodiles. ''Proterosuchus'' is one of the earliest members of the clade Archosauriformes, which also includes crocodilians, pterosaurs, and dinosaurs, includin ...

Erythrosuchus
''Erythrosuchus'' (from el, ἐρυθρός , 'red' and el, σοῦχος , 'crocodile') is an extinct genus of archosauriform reptile from the Triassic of South Africa. Remains have been found from the Cynognathus Assemblage Zone of the Beaufort Group in the Karoo of South Africa. In the Late Triassic, the ecological niche left by ''Erythrosuchus'' was filled by archosaurs like ''Saurosuchus'' and ''Postosuchus''. Description ''Erythrosuchus'' was the largest predator of its time, and was around long. It walked on all fours and had limbs which were positioned semi-vertically under its body, unlike the more sprawling gait of most earlier reptiles. Its head was large and theropod-like, reaching a length of , and had sharp, conical teeth. ''Erythrosuchus'' was the largest erythrosuchid, but apart from its size, was largely similar in appearance to other related genera. It had a large head and comparatively short neck.

Fugusuchus
''Fugusuchus'' is an extinct genus of archosauriform, probably the basal-most member of the family Erythrosuchidae. The genus is known from a single fossil from the middle Early Triassic Heshanggou Formation in Shanxi, China. The partial skeleton consists of an incomplete skull, parts of the right forelimb, and an intercentrum. The skeleton, known as GMB V 313, is currently in the Geological Museum of China in Beijing. ''Fugusuchus'' was a medium-sized archosauriform. It has a long and relatively low skull, unlike the higher more pointed skulls of related genera such as ''Erythrosuchus''. In ''Fugusuchus'', the tooth row of the upper jaw extends beneath the orbit, or eye socket. This feature distinguishes it from more advanced erythrosuchids such as ''Garjainia ''Garjainia'' is an extinct genus of erythrosuchid archosauriform reptile from the Olenekian of Russia and South Africa.

Cladogram
A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an 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 evolutionary narratives about ance ...

Paraphyletic
In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its descendants, excluding a few Monophyly, monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of Synapomorphy and apomorphy, synapomorphies and symplesiomorphy, symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia (reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
