11.2" Discosauriscus (Permian Reptiliomorph) - Franchesse, France

This is a museum quality, 11.2" long amphibian (Discosauriscus austriacus) from the Lower Permian beds near Franchesse, France. The skin and soft parts are naturally and exceptionally well preserved. Along with the complete individual there are two partial specimens and an isolated skull on the 23 x 16" section of shale. There are repairs through the rock, but no restoration has been done to the specimens.

A new vertebrate Lagerstätte from the Lower Permian of France (Franchesse, Massif Central): palaeoenvironmental implications for the Bourbon-l’Archambault basin

Discosauricus was a small seymouriamorph that lived in Central Europe during the Lower Permian Period. Many seymouriamorphs were terrestrial or semi-aquatic. However, aquatic larvae bearing external gills and grooves from the lateral line system have been found, making them unquestionably amphibians. The adults were terrestrial. Some of the best fossils of Discosauricus species have been found in Boskovice basin in the Czech Republic.

Because the skeletons of Discosauriscus were lightly sclerotized, they are rarely as well preserved as the intact specimen found on this plate. This fossil clearly defines the wide jaws, short limbs, and relatively long tail of this species. A well-preserved, lateral-line system has been described by researchers, which suggests that Discosauriscus may have had electroreceptive organs.
