Trematolestes
''Trematolestes'' is an extinct genus of temnospondyl amphibian from the Lower Keuper (Ladinian, Middle Triassic) of southern Germany. It was first named by Rainer R. Schoch in 2006 and the type species is ''Trematolestes hagdorni''. It is the first trematosaurid represented by a nearly complete skeleton.

Trematosauridae
Trematosauridae are a family of large marine temnospondyl amphibians with many members. They first appeared during the Induan age of the Early Triassic, and existed until around the Carnian stage of the Late Triassic, although by then they were very rare. By the Middle Triassic they had become widespread throughout Laurasia and Gondwana with fossils being found in Europe, Asia, Madagascar, and Australia. They are one of the most derived families of the Trematosauroidea superfamily in that they are the only family that have fully marine lifestyles. Long, slender snouts that are characteristic of the trematosaurids, with some members having rostrums resembling those of modern-day gavials. Traditionally, two subfamilies within Trematosauridae can be identified, the relatively short-nosed Trematosaurinae and the long-nosed Lonchorhynchinae. A third subfamily, Tertreminae, was named in 2000 and includes broad-snouted forms like '' Tirraturhinus''. Below is a cladogram from St ...

Tertremoides
''Tertremoides'' is an extinct genus of trematosaurian temnospondyl within the family (biology), family Trematosauridae from Madagascar. It was first named by Lehman, J-P. in 1966 as ''Trematosaurus, Trematosaurus madagascariensis'' but renamed to ''Tertremoides ambilobensis'' by Lehman in 1979. Its closest relative was ''Trematolestes''.

Trematosauroidea
Trematosauroidea are an important group of Triassic temnospondyl amphibians. They flourished briefly during the Early Triassic, occurring worldwide before declining at the start of the Middle Triassic, although the group continued until the Late Triassic. They were medium-sized temnospondyls with wedge-shaped tails, narrow skulls, and, in advanced forms, elongated snouts. The latter feature was probably an adaptation for feeding on fish. The largest and most specialized family, the Trematosauridae, are the only batrachomorphs to have adapted to a marine lifestyle with the exception of the modern crab-eating frog. A temnospondyl ilium was described in 2004 from the Callovian Toutunhe Formation in the Junggar Basin of China. Although the isolated bone was impossible to identify on the species level, it was referred to Trematosauroidea. The presence of this bone in the Toutunhe Formation extends the range of trematosauroids into the Middle Jurassic, making it one of only three g ...

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 Ma (million years ago). It is preceded by the Early Triassic Epoch and followed by the Late Triassic Epoch. The Middle Triassic is divided into the Anisian and Ladinian ages or stages. Formerly the middle series in the Triassic was also known as Muschelkalk. This name is now only used for a specific unit of rock strata with approximately Middle Triassic age, found in western Europe. Middle Triassic fauna Following the Permian–Triassic extinction event, the most devastating of all mass-extinctions, life recovered slowly. In the Middle Triassic, many groups of organisms reached higher diversity again, such as the marine reptiles (e.g. ichthyosaurs, sauropterygians, thallatosaurs), ray-finned fish and many invertebrate g ...

Triassic Temnospondyls Of Europe
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 archosau ...

Cosgriffius
''Cosgriffius'' is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae. It was described in 1993 by Samuel P. Welles based on a single partial skull from the well-known Meteor Crater Quarry (Early Triassic Moenkopi Formation) in Arizona that also produced more abundant remains of the capitosaur '' Wellesaurus peabodyi.'' The skull was long and slender, features typically associated with the trematosaurid subfamily Lonchorhynchinae. This is the only trematosaurid known from western North America. See also * Prehistoric amphibian * List of prehistoric amphibians This list of prehistoric amphibians is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be amphibians, excluding purely vernacular terms. The list includes all commonly accepted g ... References Lonchorhynchines Triassic temnospondyls of North America Taxa named by Samuel Paul Welles Fossil taxa described in 19 ...
