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.

Krkonoše皮埃蒙特盆地(捷克共和国)干羊膜动物dissauriscus (Seymouriamorpha, dissauriscdae)的首次记录

本文描述了在捷克共和国Krkonoše皮埃蒙特盆地发现的首个seymriamorph干羊膜动物dissauriscus。根据以下特征，该标本被确定为D. pulcherrimus，而这些特征在D. austracus中是不存在的:1)后颊腹外侧突的尖尖位于下颌楔形后内侧突尖的前面;(2)小齿行从翼状腭支腹面中宽处向前内侧和前外侧发散。这一新记录增加了我们对这种西摩变形在欧洲二叠-石炭系盆地中发生的认识。

期刊介绍： Fossil Imprint (formerly Acta Musei Nationalis Pragae, Series B – Historia Naturalis) is an international, open access journal, publishing original papers and reviews of any length from all areas of paleontology and related disciplines, such as palaeoanthropology, biostratigraphy, palynology, and archaeobotany/zoology. All taxonomic groups are treated, including plants, invertebrates, vertebrates, microfossils, and ichnofossils, with a special emphasis on terrestrial and post-Palaeozoic marine biota. We encourage the publication of international meetings as well as special thematic issues. The aim of the journal is to spread the scientific knowledge with no restrictions, and to allow access to it to any interested person. Each article includes information about the date of receiving, accepting and issue.
