Sixty-one dinoflagellate cyst taxa have been found in fine-grained deposits of the Šambron beds that occur below and above the Pucov Member (Central Carpathian Palaeogene, Slovakia). These deposits have been studied from two localities at Orava: Zadný Krnáč and Pucov. Age-assess- ment of the dinocyst assemblages suggests their latest Middle-Late Eocene age. Two dinocyst assemblages of different composition have been recognized. The Impagidinium-dominated assem- blage reflects offshore depositional conditions, whereas the Homotryblium-dominated one represents inshore palaeoenvironment. Scarcity of Peridiniales in these dinocyst assemblages presumably reflects low nutrient availability, whereas their co-occurrence with oligotrophic species may result from surface water stratification.
