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 ...

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 ...

Smilesaurus
''Smilesaurus'' is an extinct genus of gorgonopsian known from Africa. It lived during the Late Permian. It contains the single species ''S. ferox''. Description ''Smilesaurus'' was a large gorgonopsian, with a skull length of up to 31 centimeters. It is characterized by extremely long canine teeth, and has the proportionally longest canines of any gorgonopsian. Unlike other gorgonopsians, which probably hunted similarly to predatory reptiles, ''Smilesaurus'' probably was a true saber-toothed predator which hunted using similar tactics to saber-toothed cats. It can be distinguished by other rubidgeines by its lack of cranial pachyostosis and rugosoties, and by its relatively small orbits. Classification The classification of ''Smilesaurus'' has been disputed. It has often been included in Rubidgeinae, but it differs from other members of the clade considerably. Instead, it may be more closely related to ''Arctops'', a position supported by a phylogenetic analysis in 2018. Belo ...

Nochnitsa
''Nochnitsa'' (rus.: ночница, literally – nightling) is a genus of gorgonopsian therapsid from the Kotelnich red beds of Permian Russia. It contains one species, ''Nochnitsa geminidens''. It the most basal known gorgonopsian and among the smallest members of the clade known to date. Discovery and naming ''Nochnitsa'' is known from only one specimen, the holotype KPM 310. It was found in Vanyushonki Member of the Kotelnich red beds, along the Vyatka River in Kirov Oblast, which dates to the latest Guadalupian or early Lopingian epochs. ''Nochnitsa'' is named after the Nocnitsa, a nocturnal hag-like creature from Slavic mythology. Its name was intended as a parallel to the Gorgons, similarly hag-like creatures from Greek mythology, which are the namesake of many genera within Gorgonopsia and the clade as a whole. The name also reflects the nocturnal habits inferred for the genus. The type species name, ''N. geminidens'', means "twin tooth" and refers to one of the autapo ...

Viatkogorgon
''Viatkogorgon'' is a genus of gorgonopsian (a type of therapsid, the group that includes modern mammals) that lived during the Permian period in what is now Russia. The first fossil was found at the Kotelnich locality near the Vyatka River and was made the holotype of the new genus and species ''V. ivachnenkoi'' in 1999. The generic name refers to the river and the related genus ''Gorgonops''—the gorgons of Greek mythology are often referenced in the names of the group. The specific name honors the paleontologist Mikhail F. Ivakhnenko. The holotype skeleton is one of the most complete gorgonopsian specimens known and includes rarely preserved elements such as gastralia (abdominal ribs) and a sclerotic ring (a bony ring inside the eye). A larger, but poorly preserved specimen has also been assigned to the species. The holotype specimen is about long, including the long skull, making ''Viatkogorgon'' a relatively small gorgonopsian. The assigned specimen is larger, with a ...

Eriphostoma
''Eriphostoma'' is an extinct genus of gorgonopsian therapsids known from the Middle Permian (middle Capitanian stage) of ''Tapinocephalus'' Assemblage Zone, South Africa. It has one known species, ''Eriphostoma microdon'', and was first named by Robert Broom in 1911. It is the oldest known gorgonopsian and among the smallest and most basal members of the clade. Description Gorgonopsians were a morphologically conservative group, and like all gorgonopsians, ''Eriphostoma'' would have been a quadrupedal predator. It was among the smaller members of the group, with a skull less than long. It had a relatively short, deep snout and large orbits compared to other gorgonopsians. Like all gorgonopsians, it had five incisors and a canine tooth on each side of the upper jaw, but it had only three small postcanine teeth in its maxilla. The palate of ''Eriphostoma'' has delta-shaped palatine bosses covered in numerous teeth, like ''Gorgonops'' and many basal therapsids, but not more der ...

Prehistoric Therapsid Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ...

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.

Rubidgeinae
Rubidgeinae is an extinct subfamily of gorgonopsid therapsids known only from Africa. They were among the largest gorgonopsians, and their fossils are common in the Cistecephalus and Daptocephalus assemblage zones of the Karoo Basin. They lived during the Late Permian, and became extinct at the end of the Permian. Description Rubidgeines were large, quadrupedal carnivores of the family Gorgonopsidae. Their largest teeth are their upper canines, which were blade-like and had well-developed serrations. Their postcanine teeth were small and conical, but were also frequently serrated. Tooth replacement was rapid relative to basal therocephalians. Rubidgeines can be distinguished from other gorgonopsians by the absence of a blade-like parasphenoid bone and reduced or absent preparietal bone. The jugal bone, while narrow in most gorgonopsians, was often broadly expanded in rubidgeines. The largest rubidgeins were ''Dinogorgon'' and ''Rubidgea''. Paleobiology Rubidgeines were among ...

Arctops
''Arctops'' ("Bear face") is an extinct genus of gorgonopsian therapsids known from the Late Permian of South Africa. It measured up to in length and its skull was long. The type species is ''Arctops willistoni''. A second species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate s ..., ''A. watsoni'', may be synonymous with ''A. willistoni''. ''A. kitchingi'' may be a third species of ''Arctops'', but it was only tentatively assigned to the genus when it was first named. Both were formally synonymized with ''A. willistoni'' by Christian Kammerer in 2017.
