Arctognathus
''Arctognathus'' is an extinct genus of gorgonopsids that throve during the Late Permian in the Karoo basin of what is now South Africa. Discovery A carnivore, like all gorgonopsid, ''Arctognathus'' was given its name ("Bear jaw") in reference to its short and rounded snout. There is only one recognized species, ''A. curvimola''. Description It was a small gorgonopsid with a total length estimated at 1.1 m and an 18 cm skull.

Gorgonopsia
Gorgonopsia (from the Greek Gorgon, a mythological beast, and 'aspect') is an extinct clade of sabre-toothed therapsids from the Middle to Upper Permian roughly 265 to 252 million years ago. They are characterised by a long and narrow skull, as well as elongated upper and sometimes lower canine teeth and incisors which were likely used as slashing and stabbing weapons. Postcanine teeth are generally reduced or absent. For hunting large prey, they possibly used a bite-and-retreat tactic, ambushing and taking a debilitating bite out of the target, and following it at a safe distance before its injuries exhausted it, whereupon the gorgonopsian would grapple the animal and deliver a killing bite. They would have had an exorbitant gape, possibly in excess of 90°, without having to unhinge the jaw. They markedly increased in size as time went on, growing from small skull lengths of in the Middle Permian to bear-like proportions of up to in the Upper Permian. The latest gorgonopsia ...

List Of Therapsids
This list of therapsids is an attempt to create a comprehensive listing of all genera that have ever been included in the Therapsida excluding mammals and purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful ('' nomina dubia''), or were not formally published (''nomina nuda''), as well as junior synonyms of more established names, and genera that are no longer considered therapsids. The list currently contains 510 generic names. Naming conventions and terminology Naming conventions and terminology follow the International Code of Zoological Nomenclature. Technical terms used include: * Junior synonym: A name which describes the same taxon as a previously published name. If two or more genera are formally designated and the type specimens are later assigned to the same genus, the first to be published (in chronological order) is the senior synonym, and all other instances are junior synonyms.

Rubidgea
''Rubidgea'' is a genus of Gorgonopsia, gorgonopsid from the upper Permian of South Africa and Tanzania, containing the species ''Rubidgea atrox''. The generic name ''Rubidgea'' is sometimes believed to be derived from the surname of renowned Karoo paleontologist, Professor Bruce Rubidge, who has contributed to much of the research conducted on therapsids of the Karoo Supergroup, Karoo Basin. However, this generic name was actually erected in honor of Rubidge's paternal grandfather, Sydney Rubidge, who was a renowned fossil hunter. Its species name ''atrox'' is derived from Latin, meaning “fierce, savage, terrible”. ''Rubidgea'' is part of the gorgonopsian subfamily Rubidgeinae, a Derived (phylogenetics), derived group of large-bodied gorgonopsians restricted to the Late Permian (Lopingian). The subfamily Rubidgeinae first appeared in the Tropidostoma Assemblage Zone, ''Tropidostoma'' Assemblage Zone. They reached their highest diversity in the ''Cistecephalus Assemblage Zone, ...

Aelurognathus
''Aelurognathus'' is an extinct genus of gorgonopsian therapsids from the Permian of South Africa. Discovery The type species is ''Aelurognathus tigriceps'', originally named ''Scymnognathus tigriceps'' by South African paleontologists Robert Broom and Sydney H. Haughton in 1913, and later assigned to the new genus ''Aelurognathus'' by Haughton in 1924. ''Scymnognathus parringtoni'' von Huene, 1950, previously assigned to ''Aelurognathus'', is now classified as a species of ''Sauroctonus''. ''Aelurognathus nyasaensis'' Haughton, 1926 is not referable to the genus.Kammerer CF.

Inostrancevia
''Inostrancevia'' is an extinct genus of carnivorous therapsids, containing the largest members of gorgonopsians, predators characterized by long, saber-tooth-like canines. The various species inhabited European Russia during the Upper Tatarian (Vyatskian), a Russian regional stage equivalent to the Wuchiapingian and Changhsingian stage of the Late Permian period, dating from approximately 259 to 252.3 million years ago. The genus name was described posthumously, after the Bolshevik Revolution, by the Russian paleontologist Vladimir P. Amalitsky in 1922, in honor of geologist Aleksandr Inostrantsev. The first fossils attributed to ''I. alexandri'' are found in Arkhangelsk Oblast, near the Northern Dvina at the end of the 19th century, making it the first gorgonopsian known from Russia, the only place outside Africa where they are officially recognized. Some fossils of the species in question are among the most complete remains of gorgonopsians ever identified to date, the ...

Lycaenops
''Lycaenops'' ("wolf-face") is a genus of carnivorous therapsids. It lived during the Middle Permian to the early Late Permian, about 260 mya, in what is now South Africa. Description ''Lycaenops'' measured about and weighed up to . Like the modern-day wolves from which it takes its name, ''Lycaenops'' had a long and slender skull, with a set of dog-like fangs set into both its upper and lower jaws. These pointed canine teeth were ideal for the use of stabbing and/or tearing at the flesh of any large prey that it came upon. ''Lycaenops'' most likely hunted small vertebrates such as reptiles and dicynodonts. ''Lycaenops'' walked and ran with its long legs held close to its body. This is a feature found in mammals, but not in more primitive amniotes, early reptiles, and synapsids such as pelycosaurs, whose legs are positioned to the sides of their bodies. The ability to move like a mammal would have given ''Lycaenops'' an advantage over other land vertebrates, since it would hav ...

Gorgonops
''Gorgonops'' (from el, Γοργών 'Gorgon' and 'eye, face', literally 'Gorgon eye' or 'Gorgon face') is an extinct genus of gorgonopsian therapsids, of which it is the type genus, having lived during the Late Permian (Wuchiapingian), about 260–254 million years ago in what is now South Africa. Despite its popularity, ''Gorgonops'' is a medium-sized gorgonopsian (about long maximum), regularly confused by the general public with the more massive ''Inostrancevia'', known from Russia, due to their similar appearance and the various media that tend to refer them by the name of the group they belong rather than by their genus names, which does not help in differentiation. History of discovery The holotype of the type species, ''Gorgonops torvus'', was in 1876 one of the first therapsids described, by Richard Owen, who also coined the name "Dinosauria" on the basis of the first known dinosaur fossils. It was also used as the type for which Richard Lydekker described the family ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
