Trematosaurus is an extinct genus of temnospondyl amphibian found in Germany and Russia.[1] It was first named by Hermann Burmeister in 1849 and the type species is Trematosaurus brauni.[1]
Classification
Below is a cladogram from Steyer (2002) showing the phylogenetic relationships of trematosaurids:[2]
Species
Valid species
- The type species, Trematosaurus brauni (Burmeister, 1849) is known from the middle member of variegated sandstone in the vicinity of Bernburg, Germany.
- T. galae (Novikov, 2010) is known from fragmentary specimens found in Lower Triassic Donskaya Luka locality (Volgograd Region), Russia.
Reclassified species
- T. fuchsi (Seidlitz, 1920) is known from the same stratigraphic level of German Basin, Thuringia. It is a junior synonym of T. brauni.
- T. thuringiensis (Werneburg, 1993) is also known from Thuringia.
- T. madagascariensis (Lehman, 1966) referred by Schoch & Milner, 2000, to Tertremoides (Lehman, 1979).
- South African T. kannemeyeri (Broom, 1909), described based on a skull fragment, most likely belongs to the genus Aphaneramma or a closely related lonchorhynchine.
- Another South African species, T. sobeyi (Haughton, 1915), was assigned to its own genus Trematosuchus (Watson, 1919).
- East European trematosaurid remains referred to Trematosaurus in fact belong to the genus Inflectosaurus Shishkin, 1960 (Novikov, 2007).
