Upper Maestrichtian coccoliths of the Lublin Upland

Abstract

The Żyrzyn Beds (Upper Maestrichtian) of the Lublin Upland yield a rich and well-preserved assemblage of calcareous nannoplankton in which 54 coccolith species belong to 34 genera were identified by the SEM method. The recognized assemblage is typical of the coccolith zone Nephrolithus frequens of the uppermost Maestrichtian.
