Název v původním jazyce

Předboj and Hoher Stein: Two sites of mass roveacrinid occurrence (Crinoidea, Cenomanian, Bohemian-Saxonian Cretaceous Basin)

Popis výsledku v původním jazyce

Roveacrinid crinoids from two upper Cenomanian localities of the Bohemian-Saxonian Cretaceous Basin are described. The well known Hoher Stein locality (Saxony) and the Předboj locality (Bohemia) provided rich collections of roveacrinids and other fauna. Biostratigraphy based on foraminifera and nanno-plankton showed that Hoher Stein is somewhat older than Predboj (Rotalipora cushmani x Whiteinella archaeocretacea zones). Lebenharticrinus canaliculatus gen. et sp. nov. is described. The species Roveacrinus geinitzi Schneider dominates at Hoher Stein while R. alatus Douglas, R. communis Douglas, Lebenharticrinus canaliculatus gen. et sp. nov. and Styracocrinus peracutus (Peck) are much more rare. The Předboj site is dominated by the species R. alatus while R. communis and L. canaliculatus gen. et sp. nov. are rare and Styracocrinus peracutus and R. geinitzi are missing. In the large numbers of isolated brachials, most proximal ossicles of the species of Roveacrinus were identified. Special Osteocrinus-like, long, rod shaped ossicles were also found and described, and tentatively considered as parts of arms of L. canaliculatus and S. peracutus. Skeletal structures were studied in all species, especially the canal system of dorsal cup parts in L. canaliculatus and S. peracutus. Mass occurrences of studied crinoids most probably reflect the enormously large offshore populations of crinoids, their adequately elevated land-ward transport and following death in shallow waters near the cliff.
