Trace fossils from Late Carboniferous storm

Eighteen ichnospecies (trvo new) referred to 17 ichnogenera (one new) as well as formally unclassified equilibńchnia, fugichnia and faecal pellets constifute a diverse and well-preserved invertebrate trace fossil suite present in storm deposits within the Fran-ciszka X marine horizon of the lŁuśov Beds (Late Carboniferous Namurian A, Pen-dleian) as exposed in the Kozłowa Góra quarry, Upper Silesia, Poland. The new forms are Fimbrirubichnus biseriąlis igen. et isp. n., which is interpreted as the work of a deposirfeeding bellerophont gastropod, and Cylindńchnus candel,abrus isp. n. An emended diagnosis of the ichnospecies Parahaentzschelinia ardelia is given. Presence of the trace fossils marks a marine influence, so that they can be utilized to discern marine versus nonmarine deposition within the ParaLc Series of the Upper Silesia Coal Basin in which other paleontological evidence is scanĘ or lacking
