D.austriacus |
Discosauriscus was a small amphibian that lived in Central and Western Europe in the Lower Permian Period. Its best fossils have been found in Boskovice Furrow, in the Czech Republic.
[edit] Classification
Discosauriscus belongs in alternative classifications to the order Anthracosauria or Seymouriamorpha, and is the type genus of the family Discosauriscidae. Currently recognised are two valid species - Discosauriscus austriacus and Discosauriscus pulcherrimus. Letoverpeton is a junior synonym of Discosauriscus.[1]
[edit] Characteristics
Discosauriscids are only known from larval or neotenic forms[2] and three ontogenetic stages can be distinguished. [3]Discosauriscus had wide jaws with sharp teeth, short limbs and relatively long tail [4]. The phalangeal formula was 2-3-4-5-3 for both hind- and forelimbs. The body was covered with rounded scales with concentric rings, and a well preserved lateral-line system has been described .[5]. Letoverpeton is a junior synonym of Discosauriscus.
It has been suggested that Discosauriscus may have had electroreceptive organs[6].
