Dinoflagellate cyst biostratigraphy of the Oxfordian and Kimmeridgian of Poland

Abstract

The dinollagellate cyst biostratigraphy of ammonite-dated Oxfordian and Kimmeridgian samples from Central Poland is presented. The dinoflagellate cysts are correleled with the Danish/English zonation established by DAVEY (1979, 1982), WOOLLAM & RIDING (1983) and emended by NØHR-HANSEN (1986), RIDING & THOMAS (1988), and the Author (POULSEN 1991a). Dinoflagellate cysts from the Bimammatum and Planula Zones in Poland confirm the correlation of these two zones with the Rosenkrantzi and Baylei Zones. Kimmeridgian dinoflagellate cysts from an upper part of the Divisum Zone to a lower part of the Mutabilis Zone in Poland indicate correlation with the mid-Mutabilis Zone of England.
