Dinoflagellate cyst biostratigraphy of the Oxfordian and Kimmeridgian of Poland

The dinoflagellate cyst biostratigraphy of ammonite-dated Oxfordian and Kimmeridgian samples from Central Poland is presented. The dinoflagellate cysts are correlated with the Danish/English zonation. 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.
