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
(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.
