6.8" Early Permian Reptiliomorph (Discosauriscus) - Czech Republic

Discosauriscus 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 Discosauriscus 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.
