Species

Valid species
T. brauni
  • 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).
gollark: Yes, I know THAT much.
gollark: I mostly want to know how the apioids it is waiting for a process to exit and doing other stuff without threads.
gollark: There are no comments beyond stuff like `case '2': /* sig usr2 */`.
gollark: Wow, this is immensely cryptic.
gollark: Muahahaha.
