Procyclotosaurus
''Procyclotosaurus'' is an extinct genus of stenotosaurid capitosaurian temnospondyl. The type species is ''P. stantonensis''. In 1904, English paleontologist Arthur Smith Woodward described it as a species of ''Capitosaurus'', ''C. stantonensis'', based on a partial skull known as R 3174. In 1958, the species was assigned to the new genus. It is known from the Lower Keuper, a European stratigraphic unit that was deposited during the late Middle Triassic.Witzmann, Florian & Sachs, Sven & Nyhuis, Christian. (2016).

Stenotosaurus
''Stenotosaurus'' is an extinct genus of capitosaurian temnospondyl within the family Stenotosauridae. It is known from three species, all of which lived during the Anisian stage of the Middle Triassic In the geologic timescale, the Middle Triassic is the second of three epochs of the Triassic period or the middle of three series in which the Triassic system is divided in chronostratigraphy. The Middle Triassic spans the time between Ma and .... Fossils have been found in England and Germany.

Mastodonsauroidea
The Mastodonsauroidea are an extinct superfamily of temnospondyl amphibians known from the Triassic. Fossils belonging to this superfamily have been found in North America, Greenland, Europe, Asia, and Australia. The genus '' Ferganobatrachus'' from the Jurassic of Asia was initially included in this superfamily but later reinterpreted as a brachyopid and given a new name Gobiops ''Gobiops'' is an extinct genus of temnospondyl from the Jurassic of Mongolia, China, and possibly Kyrgyzstan. The genus is represented by a single species, ''Gobiops desertus''. It was named in 1991 from the Late Jurassic Shar Teeg Beds of Mong ....

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 ...

Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...

Wellesaurus
''Wellesaurus'' is an extinct genus of mastodonsauroid temnospondyl. They were amphibious carnivores that lived in freshwater environments. ''Wellesaurus'' encompasses several species which were connected when the genus was named in 1971. The type species, ''Wellesaurus peabodyi'', was originally named as ''Parotosaurus peabodyi'' in 1965. This species is based on UCMP 36058, a complete skull from the Wupatki Member of the Moenkopi Formation in Arizona. Many other skulls have been recovered from the area and referred to the species. ''Wellesaurus peabodyi'' is often considered synonymous with '' Stanocephalosaurus birdi'', a contemporaneous capitosaur named in 1933. Another potential species, ''Wellesaurus africanus'', is from subzone B of the ''Cynognathus'' Assemblage Zone in South Africa. Although this species was originally formulated in 1909, the fragmentary preservation of its material has prevented precise conclusions on its affinities. As a result, it has been referred ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
