Parioxys
''Parioxys'' is an extinct genus of temnospondyl amphibian from the Early Permian of Texas. History of study The type species, ''Parioxys ferricolus'', was named in 1878 by American paleontologist Edward Drinker Cope based on two badly preserved skulls that were collected from the early Permian Texas red-beds. Egyptian paleontologist Youssef S. Moustafa, described new material of ''P. ferricolus'' from other localities in Texas. This taxon was recently redescribed by Schoch & Sues (2022). Moustafa also described another species, ''P. romeri'', on the basis of an isolated humerus, but this was regarded as being indeterminate. A second definitive species, ''P. bolli'', was described by Canadian paleontologist Robert Carroll in 1964. This taxon is only known from postcranial material. Relationships ''Parioxys'' was historically considered to be closely related to eryopoids, more specifically the well-known '' Eryops megalocephalus'', which was collected from the same locality ...

Dissorophidae
Dissorophidae is an extinct family of medium-sized, temnospondyl amphibians that flourished during the late Carboniferous and early Permian periods. The clade is known almost exclusively from North America. History of study Dissorophidae is a diverse clade that was named in 1902 by George A. Boulenger. Junior synonyms include Otocoelidae, Stegopidae, and Aspidosauridae. Early in the study of dissorophoids when the relationships of different taxa were not well-resolved and most taxa had not been described, Dissorophidae sometimes came to include taxa that are now not regarded as dissorophids and may have excluded earlier described taxa that are now regarded as dissorophids. Amphibamiforms were widely regarded as small-bodied dissorophids, and at one point, Dissorophidae was also suggested to also include Trematopidae. 19th century In 1895, American paleontologist Edward Drinker Cope named ''Dissorophus'' from the early Permian of Texas. This was the first dissorophid to be d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kamacops
''Kamacops'' is a genus of dissorophid temnospondyls known from the Middle to Late Permian of Russia that was described by Yuri Gubin in 1980. It is known from a single species, ''Kamacops acervalis,'' material of which is currently reposited in the Paleontological Institute of the Russian Academy of Sciences. ''Kamacops'' is one of the youngest dissorophids, along with '' Iratusaurus'' and '' Zygosaurus'' from Russia and ''Anakamacops'' from China and was one of the largest known dissorophids, with an estimated skull length of 24–30 cm. It is typically recovered as being most closely related to ''Zygosaurus'' and to the North American ''Cacops ''Cacops'' ("ugly look" for its strange appearance), is a genus of dissorophid temnospondyls from the Kungurian stage of the early Permian of the United States.

Eucacopinae
Eucacopinae is an extinct clade (evolutionary grouping) of dissorophid temnospondyls. Eucacopines differ from the other main group of dissorophids, the Dissorophinae, in having more lightly built skeletons and more knobby skulls. The subfamily was originally named Cacopinae, but since the name was already established for a group of living microhylid frogs in 1931, the name was changed to Eucacopinae in 2013. Eucacopinae is a stem-based taxon defined as the most inclusive clade containing the species '' Cacops apsidephorus'' but not '' Dissorophus multicinctus'', which belongs to Dissorophinae. According to the most recent phylogenetic analyses of Dissorophidae, Eucacopinae includes the basal ("primitive") species ''Conjunctio multidens'' and '' Scapanops neglecta'' from the southwestern United States and a more derived ("advanced") group including several species of ''Cacops'' (also from the southwestern United States) and the Russian genera ''Kamacops'' and '' Zygosaurus''.

Trematopidae
Trematopidae is a family of dissorophoid temnospondyl spanning the late Carboniferous to the early Permian. Together with Dissorophidae, the family forms Olsoniformes, a clade comprising the medium-large terrestrial dissorophoids. Trematopids are known from numerous localities in North America, primarily in New Mexico, Oklahoma, and Texas, and from the Bromacker quarry in Germany. History of study The clade Trematopidae was first proposed by American paleontologist S.W. Williston in 1910, although it was named as "Trematopsidae" following the historical (but inaccurate) derivation from the genus "''Trematops''" (now synonymized with ''Acheloma''). British paleontologist D.M.S. Watson proposed a related clade in 1919, Achelomidae, for ''Acheloma'', based on perceived differences separating the taxa; this is now considered a junior synonym of Trematopidae following guidelines of historical precedent. 19th century history In 1882, American paleontologist Edward Drinker Cope na ...

Eryops
''Eryops'' (; from Greek , , 'drawn-out' + , , 'face', because most of its skull was in front of its eyes) is a genus of extinct, amphibious temnospondyls. It contains the single species , the fossils of which are found mainly in early Permian (about 295 million years ago) rocks of the Texas Red Beds, located in Archer County, Texas. Fossils have also been found in late Carboniferous period rocks from New Mexico. Several complete skeletons of ''Eryops'' have been found in lower Permian rocks, but skull bones and teeth are its most common fossils. Description ''Eryops'' averaged a little over long and could grow up to , making them among the largest land animals of their time. Adults weighed between . The skull was proportionately large, being broad and flat and reaching lengths of . It had an enormous mouth with many curved teeth like the frog. Its teeth had enamel with a folded pattern, leading to its early classification as a "labyrinthodont" ("maze toothed"). The sh ...

Eryopoidea
Eryopoidea are a taxon of late Carboniferous and Permian temnospondyli amphibians, known from North America and Europe. Carroll includes no fewer than ten families, but Yates and Warren replace this with a cladistic approach and include three families, the Eryopidae, Parioxyidae and Zatrachydidae. They define the Eryopoidea as all Euskelia in which the choana are relatively rounded and the iliac blade The crest of the ilium (or iliac crest) is the superior border of the wing of ilium and the superiolateral margin of the greater pelvis. Structure The iliac crest stretches posteriorly from the anterior superior iliac spine (ASIS) to the posteri ... vertical. A similar definition but without the Euskelia is provided by Laurin and Steyer. References External linksPalaeos – Mikko's Phylogeny Archive {{Taxonbar, fro ...

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 ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
