Temnospondyli
Temnospondyli (from Greek τέμνειν, ''temnein'' 'to cut' and σπόνδυλος, ''spondylos'' 'vertebra') is a diverse order of small to giant tetrapods—often considered 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 characteristics, such as scales and armour-like bo ...

''Trucheosaurus'' is an extinct genus of rhytidosteid temnospondyl from the Late Permian period of the Sydney Basin, New South Wales, Australia. It is known from the holotype materials MMF 12697a, a partially complete skull, AMF 50977, an articulated postcranial skeleton and BMNHR 3728, the counterpart of both skull and postcranial skeleton, recovered from the Glen Davis Formation. This genus was named by Watson in 1956, and the type species is ''Trucheosaurus major''.

Stereospondyli
The Stereospondyli are a group of extinct temnospondyl amphibians that existed primarily during the Mesozoic period. They are known from all seven continents and were common components of many Triassic ecosystems, likely filling a similar ecological niche to modern crocodilians prior to the diversification of pseudosuchian archosaurs. Classification and anatomy The group was first defined by Zittel (1888) on the recognition of the distinctive vertebral anatomy of the best known stereospondyls of the time, such as '' Mastodonsaurus'' and ''Metoposaurus''. The term 'stereospondylous' as a descriptor of vertebral anatomy was coined the following year by Fraas, referring to a vertebral position consisting largely or entirely of the intercentrum in addition to the neural arch. While the name 'Stereospondyli' is derived from the stereospondylous vertebral condition, there is a diversity of vertebral morphologies among stereospondyls, including the diplospondylous (' tupilakosaurid') ...

Bothriceps
''Bothriceps'' is an extinct genus of stereospondyl temnospondyl. It is a member of the infraorder Trematosauria and is the most basal brachyopomorph known. It is one of the only brachyopomorph that lies outside the superfamily Brachyopoidea, which includes the families Brachyopidae and Chigutisauridae. It shares several similarities to ''Keratobrachyops'', another basal brachyopomorph, and may be closely related to or even synonymous with it. The genus was named in 1859 by Thomas Henry Huxley with the description of its type species ''B. australis'' from the Early Triassic Upper Parmeener Group of Tasmania, Australia Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. With an area of , Australia is the largest country by .... It was originally assigned to the family Brachyopidae and was not reassigned to a more basal position until ...

Trematosauria
Trematosauria is one of two major groups of temnospondyl amphibians that survived the Permian-Triassic extinction event, the other (according to Yates and Warren 2000) being the Capitosauria. The trematosaurs were a diverse and important group that included many medium-sized to large forms that were semi-aquatic to totally aquatic. The group included long-snouted forms such as the trematosauroids and short, broad-headed forms such as the metoposaurs.Brusatte, S. L., Butler R. J., Mateus O., & Steyer S. J. (2015).

Brachyopoidea
Brachyopoidea is a superfamily of temnospondyls that lived during the Mesozoic. It contains the families Brachyopidae and Chigutisauridae. The earliest records of brachyopids are from the Lower Triassic in Australia. The latest-surviving member of the superfamily is the chigutisaurid ''Koolasuchus'' from the Early Cretaceous of Australia. Description Some large brachiopoids, such as ''Siderops'' and ''Koolasuchus'', grew to lengths of around . However, an unnamed Late Triassic or Early Jurassic brachiopoid from Lesotho in southern Africa is estimated to have been far larger. At an estimated , the brachiopoid from Lesotho is one of the largest amphibians '' sensu lato'' ever known. This estimate is based on a single jaw fragment found in 1970 by a French expedition near Alwynskop in Quthing. Because of its size, the fragment was initially considered to be from a mastodonsaur. However, Several features of the specimen indicate that it is from a brachyopoid. There is a larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
