Abstract
Abstract The Langsettian species Cordaites karvinensis Šimůnek and C. sustae Šimůnek were found conspecific, with C. karvinensis chosen as a correct name. These species come from the same coal seam of the Upper Suchá Member (Upper Silesian Basin, the Czech Republic). Abaxial cuticle from C. karvinensis was found conspicuously similar to Cordaabaxicutis cf. jaworznoensis from the Lower Suchá Member from the strata near the Namurian/Westphalian boundary, as well as to Cordaabaxicutis jaworznoensis Šimůnek et Florjan described from the Orzesze Beds (Duckmantian) from Poland. The abaxial cuticles of all these species are papillate. It is probable that these species are members of one evolutionary lineage, however without information on the leaf morphology connected to the dispersed cuticles of Cordaabaxicutis, this opinion remains hypothetical.
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.
