Melosaurinae
Melosaurinae is an extinct subfamily of temnospondyl amphibians, part of the family Archegosauridae. Most melosaurines are known from Russia, although an unnamed species has been found in Brazil. Unlike the long-skulled archegosaurids of the family Platyoposaurinae, melosaurines have shorter, broadened snouts.

Archegosauridae
Archegosauridae is a family of relatively large and long snouted temnospondyls that lived in the Permian period. They were fully aquatic animals, and were metabolically and physiologically more similar to fish than modern amphibians.Florian Witzmann; Elizabeth Brainerd (2017). "Modeling the physiology of the aquatic temnospondyl Archegosaurus decheni from the early Permian of Germany". Fossil Record. 20 (2): 105–127. doi:10.5194/fr-20-105-2017. The family has been divided into two subfamilies, the longer-snouted Platyoposaurinae and the shorter-snouted Melosaurinae.

Koinia Silantjevi
''Koinia'' is an extinct genus of temnospondyl amphibian from the Late Permian of Russia. It is an archegosauroid in the subfamily Melosaurinae. ''Koinia'' was named in 1993 with the description of the type species ''K. silantjevi'', based on fossils that were found in the Ocher Assemblage Zone Ochre ( ; , ), or ocher in American English, is a natural clay earth pigment, a mixture of ferric oxide and varying amounts of clay and sand. It ranges in colour from yellow to deep orange or brown. It is also the name of the colours produced ..., near the Vym River in the Komi Republic.

Uralosuchus Tverdochlebovae
''Uralosuchus'' is an extinct genus of temnospondyl amphibian from the Late Permian of Russia, belonging to the group Archegosauroidea. It is a member of the archegosauroidean subfamily Melosaurinae. Fossils have been found in Orenburg Oblast Orenburg Oblast (russian: Оренбургская область, ''Orenburgskaya oblast'') is a federal subject of Russia (an oblast).

Konzhukovia Vetusta
''Konzhukovia'' is an amphibian genus that belongs to an extinct group of temnospondyls, the largest clade of basal tetrapods including about 198 genera, 292 species, and more than half of which were alive during the early Mesozoic period. The animal was a predator that lived about 260 million years ago, and could get up to about three meters in length. Specifically, ''Konzukovia'' lived during the Permian, between 252 and 270 million years ago according to the type of rock the fossil was found in. There are three species within this genus, ''K. vetusta'', ''K. tarda'', and ''K. sangabrielensis'', the first two originating from Russia while the latest originating from Southern Brazil. The discovery of this specimen in Southern Brazil provided more evidence to support the idea that during this animals existence, there was a “biological corridor” because of the supercontinent Pangea, allowing these species to be found so far apart from each other.

Temnospondyl
Temnospondyli (from Greek language, Greek τέμνειν, ''temnein'' 'to cut' and σπόνδυλος, ''spondylos'' 'vertebra') is a diverse order (biology), order of small to giant tetrapods—often considered Labyrinthodontia, primitive amphibians—that flourished worldwide during the Carboniferous, Permian, and Triassic periods. A few species continued into the Jurassic and Cretaceous periods. Fossils have been found on every continent. During about 210 million years of evolutionary history, they adapted to a wide range of habitats, including freshwater, terrestrial, and even coastal marine environments. Their life history is well understood, with fossils known from the larval stage, metamorphosis, and maturity. Most temnospondyls were semiaquatic, although some were almost fully terrestrial, returning to the water only to breed. These temnospondyls were some of the first vertebrates fully adapted to life on land. Although temnospondyls are considered amphibians, many had cha ...

Archegosauroidea
Archegosauroidea is an extinct superfamily of Permian temnospondyls. The superfamily is assigned to the clade Stereospondylomorpha and is the sister taxon to the suborder Stereospondyli. It includes the families Actinodontidae and Archegosauridae, and possibly the genus ''Intasuchus'', which is placed within the monotypic family Intasuchidae. They were fully aquatic animals, and were metabolically and physiologically more similar to fish than modern amphibians.Florian Witzmann; Elizabeth Brainerd (2017).

Kashmirosaurus Ornatus
''Kashmirosaurus'' is an extinct genus of temnospondyl amphibian known from Permo-Carboniferous deposits in the region of Kashmir Kashmir () is the northernmost geographical region of the Indian subcontinent. Until the mid-19th century, the term "Kashmir" denoted only the Kashmir Valley between the Great Himalayas and the Pir Panjal Range. Today, the term encompas .... It was originally named by English paleontologist Arthur Smith Woodward in 1905 as a species of '' Archegosaurus'' called ''Archegosaurus ornatus''. More recently, the species has been recognized as being distinct from ''Archegosaurus'', and it was placed in its own genus ''Kashmirosaurus'' in 1996. An additional species of ''Archegosaurus'', ''A. kashmiriensis'', was named in 1960 from the same deposits in Kashmir, and is now considered synonymous with ''Kashmirosaurus ornatus''.

Prionosuchus Plummeri
''Prionosuchus'' is an extinct genus of large temnospondyl. A single species ''P. plummeri'', is recognized from the Early Permian (some time between 299 and 272 million years ago). Its fossils have been found in what is now northeastern Brazil. Description The fragmentary remains of this animal have been found in the Pedra do Fogo Formation in the Parnaíba Basin of Northeastern Brazil, in the states of Piauí and Maranhão, and it was described by L.I. Price in 1948. The incomplete skull of the holotype specimen has been estimated to be long.Cox, C.B., and Hutchinson, P. (1991). "Fishes and amphibians from the Late Permian Pedra de Fogo Formation of Northern Brazil" ''Palaeontology'', 34(3): 561–573. Several more fragmentary specimens have been found. One very fragmentary but very large specimen (BMNH R12005) appears to have come from an individual nearly three times the size of most other specimens, and may have had a skull that measured up to long.

Platyoposaurus Stuckenbergi
''Platyoposaurus'' was a temnospondyl from the Middle Permian epoch about 270-268 Mya. Discovery One of the discoveries includes a skull 28 cm long with a purported body length of 250 cm representing a carnivorous adult specimen. The fossil remains were found in Belebey in Bashkortostan The Republic of Bashkortostan or Bashkortostan ( ba, Башҡортостан Республикаһы, Bashqortostan Respublikahy; russian: Республика Башкортостан, Respublika Bashkortostan),; russian: Респу́блик ..., Russia; the name ''Platyoposaurus'' means "flat-faced lizard" and was coined after the original name ''Platyops'' turned out to be preoccupied.Rich, Pat Vickers, and Thomas H.

Australerpeton Cosgriffi
''Australerpeton'' is an extinct genus of stereospondylomorph temnospondyl currently believed to belong to the family Rhinesuchidae. When first named in 1998, the genus was placed within the new family Australerpetontidae. However, studies published a few years later questioned the systematics used in the original description and included the genus within Archegosauridae.Schoch, R. R. and Milner, A. R. (2000). ''Stereospondyli. Stem-stereospondyli, Rhinesuchidae, Rhytidostea, Trematosauroidea, Capitosauroidea''. Handbuch der paläoherpetologie Part 3B. 203p A study by Dias & Schultz (2003) reassigned ''Australerpeton'' to the family Rhinesuchidae within the suborder Stereospondyli based on an earlier evaluation of the family. In this study, the close similarities between ''Australerpeton'' and archegosaurids were attributed to convergent evolution as a result of similar semi-aquatic lifestyles. A redescription of the skeleton of this genus was published by Eltink & Langer in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
