Abstract

Sporomorphs, foraminifers, dinoflagellate cysts and calcareous nannoplankton were recovered from the Cretaceous dark pelitic sequences of the Main quarry Kotouč (Silesian Unit, Outer West Carpathians) overlying the Tithonian-Lower Berriasian Štramberk limestone body. Preliminary results of the biostratigraphic study enabled to distinguish two associations of microfossils of different age - late Albian-Cenomanian and Valanginian-Hauterivian age. Both Tethyan and Boreal nannofossil elements were found in the samples of the Lower Cretaceous age. Dinoflagellate cysts of Valanginian-Hauterivian age characterise the shallow neritic sea while dinocysts of Albian-Cenomanian come from deeper part of the neritic sea.
