Scymnognathus

Scymnognathus is a genus of extinct marine reptiles that lived during the Late Triassic period, approximately 230 to 200 million years ago. The genus is known from several well-preserved fossils found in Europe, particularly in Germany and Switzerland. Scymnognathus is notable for its distinctive skull structure, which features a large, toothless snout and a series of small, sharp teeth arranged in a unique pattern.

The genus includes at least two species, Scymnognathus alberti and Scymnognathus brevirostris. Both species exhibit similar skeletal features, but there are some differences in the size and shape of their skulls. Scymnognathus alberti is known from a nearly complete skull, while Scymnognathus brevirostris is represented by a more fragmentary fossil.

Scymnognathus is classified within the order Plesiosauria, which includes a diverse group of marine reptiles that evolved during the Mesozoic era. The genus is of particular interest to paleontologists due to its unique skull morphology and the insights it provides into the evolution of marine reptiles. Despite its distinctive features, the precise ecological role of Scymnognathus remains uncertain, but it is likely that it was a predator or scavenger in the marine environment of its time.
