Coccoliths and index foraminifera from the Upper Cretaceous chalk of Mielnik region, Eastern Poland
Elżbieta Gaździcka
The abundant but weakly diversified calcareous nannoplankton has been stated in the chalk of the Mielnik region. Large forms of massive structure dominate: Kamptnertus magnificus Deflandre, Broinsonia parca (Stradner), Reinhardtites
anthophorus (Deflandre), Lucianorhabdus cayeuri Deflandre. Two biostratigraphic zones: Broinsonia parca and Quadrum trifidum have heen distinguished. Foraminifera were examined in order to make a correlation with the coccolith zones.
Key words: Coccoliths, foraminifera, Campanian, stratigraphy, Poland.
