Akidnognathid
Akidnognathidae is an extinct family of therocephalian therapsids from the Late Permian and Early Triassic of South Africa, Russia and China. The family includes many large-bodied therocephalians that were probably carnivorous, including ''Moschorhinus'' and ''Olivierosuchus''. One akidnognathid, ''Euchambersia'', may even have been venomous. Akidnognathids have robust skulls with a pair of large caniniform teeth in their upper jaws. The family is morphologically intermediate between the more basal therocephalian group Scylacosauridae and the more derived group Baurioidea. Research history The first known fossils of akidnognathids consists of two skulls which were discovered during a series of excavations carried out from 1899 until 1914 by Vladimir Amalitsky and his companion in the Northern Dvina, in present-day European Russia. In an article published posthumously in 1922, Amalitsky established a new taxon of therocephalians under the name ''Anna petri'', in honor of his c ...

Euchambersia
''Euchambersia'' is an extinction, extinct genus of therocephalian therapsids that lived during the Late Permian in what is now South Africa and China. The genus contains two species. The type species ''E. mirabilis'' was named by paleontologist Robert Broom in 1931 from a skull missing the lower jaw. A second skull, belonging to a probably immature individual, was later described. In 2022, a second species, ''E. liuyudongi'', was named by Jun Liu and Fernando Abdala from a well-preserved skull. It is a member of the family Akidnognathidae, which historically has also been referred by as the synonymous Euchambersiidae (named after ''Euchambersia''). ''Euchambersia'' was a small and short-snouted therocephalian, possessing large canine tooth, canines as is typical of the group. However, it is notable among therocephalians for possessing ridges on its canines and a large indentation in the side of the skull. It has been proposed that these structures supported a venom delivery mech ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moschorhinus
''Moschorhinus'' is an extinct genus of therocephalian synapsid in the family Akidnognathidae with only one species: ''M. kitchingi'', which has been found in the Late Permian to Early Triassic of the South African Karoo Supergroup. It was a large carnivorous therapsid, reaching in total body length with the largest skull comparable to that of a lion in size, and had a broad, blunt snout which bore long, straight canines. ''Moschorhinus'' appears to have ecologically replaced the gorgonopsids as an apex predator, and hunted much like a big cat. While most abundant in the Late Permian, it survived into the Early Triassic in small numbers after the Permian Extinction, though these Triassic survivors had stunted growth. Taxonomy The genus name ''Moschorhinus'' is derived from the Ancient Greek words μόσχος (mos'-khos) ''moschos'' for calf or young animal, and ''rhin/rhino-'' for nose or snout, in reference to its short, broad snout. The species name, ''kitchingi'', refers t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olivierosuchus
''Olivierosuchus'' is an extinct genus of therocephalian therapsids. It is a member of the family Akidnognathidae. Fossils of ''Olivierosuchus'' have been found from the Early Triassic ''Lystrosaurus'' Assemblage Zone in South Africa. Unlike other akidnognathids such as '' Moschorhinus'', it has a narrow snout and fewer postcanine teeth. As a distinguishing feature, ''Olivierosuchus'' also has a sharp ridge near the choana, an opening in the skull palate. Bumps and projections cover the pterygoid, a bone that forms part of the palate. ''Olivierosuchus'' was a top predator of the lower ''Lystrosaurus'' Assemblage Zone (LAZ) and lived alongside other large therapsids like ''Moschorhinus''. The high diversity of akidnognathids in the LAZ suggests that the group recovered quickly from the Permian-Triassic extinction event, a mass extinction in which many other therapsid groups disappeared. A burrow cast described in 2010 from the LAZ has been attributed to ''Olivierosuchus'' or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Shiguaignathus'' is an extinct genus of therocephalian therapsid that lived in what is now China during the Late Permian. It was found in the Naobaogou Formation The Naobaogou Formation is a geological formation in the Daqing Mountains of China. It is likely of Lopingian (Late Permian) age. It consists of three rhythms of sediment, labeled members I-III primarily of purple siltstone, but each with a thick ... and is known from a partial skull.

Oskar Kuhn
Oskar Kuhn (7 March 1908, Munich – 1 May 1990) was a German palaeontologist. Life and career Kuhn was educated in Dinkelsbühl and Bamberg and then studied natural science, specialising in geology and paleontology, at the University of Munich, from which he received his D. Phil. in 1932. He worked in the University of Munich Geological Institute, among other things on the ''Fossilium Catalogus'' (Catalogue of Fossils), and then in 1938 on a stipend from the Deutsche Forschungsgemeinschaft, moved to the University of Halle, where he worked on the Geiseltal fossils. In 1939 he achieved his Habilitation with a thesis on the Halberstadt Keuper fauna, and in 1940 was named Privatdozent in geology and paleontology. Informed by his Catholic religion, Kuhn was an exponent of idealistic morphology: he viewed evolution as operating only within predetermined morphological classes. In 1943 he declared, "The theory of descent has collapsed." After a political conflict with his mentor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
