Abstract

The first record of the seymouriamorph stem amniote Discosauriscus from the Krkonoše Piedmont Basin (the Czech Republic) is described. The specimen is identified as D. pulcherrimus on the basis of the following features which are absent in D. austriacus: 1) the pointed tip of the ventrolateral process of the postorbital lies anteriorly to the tip of the wedge-shaped dorsomedial process of the jugal; and 2) the rows of small denticles diverge anteromedially and anterolaterally from the midwidth of the ventral surface of the palatal ramus of the pterygoid. This new record increases our knowledge of the occurrence of this seymouriamorph in the Permo-Carboniferous basins of Europe.
