abstract: Planktonic foraminifers are abundant in the Upper Cretaceous deposits of the Mountainous Crimea, and their marker species are of great importance for biostratigraphy and correlation. Globotruncanita stuarti (De Lapparent, 1918) and Pseudotextularia elegans (Rzehak, 1891) are used as index species for local and regional biostratigraphic scales, and species of the genus Rugoglobigerina Brönnimann, 1952 are used as index species for beds with fauna. The biostratigraphically important species from f
