Abstract

This study presents biostratigraphic data on the high-resolution stratigraphy of the Crimean–Caucasian region. Carbonate lithofacies of limestone, marl, clayey limestone, and chalk prevail in the Upper Cretaceous.The new proposed foraminiferal scheme consists of 15 zones: upper Albian Thalmanninella appenninica, lower Cenomanian Thalmanninella globotruncanoides, lower–middle Cenomanian Thalmanninella deeckei, middle–upper Cenomanian Rotalipora cushmani, upper Cenomanian–lower Turonian Whiteinella archaeocretacea, lower Turonian Hedbergella helvetica, middle Turonian Marginotruncana pseudolinneiana, upper Turonian–lower Coniacian Marginotruncana coronata, middle–upper Coniacian–lower Santonian Concavatotruncana concavata, lower–upper Santonian Contusotruncana asymetrica, upper Santonian–lower Campanian Globotruncana elevata, middle Campanian Globogirinelloides multispinus, upper Campanian Contusotruncana morozovae, upper Campanian–lower Maastrichtian Globotruncanita stuarti, and Maastrichtian Abathomphalus mayaroensis, with 18 infrazonal bioevents. The radiolarian scheme consists of six zones: upper Albian Crolanium cuneatum, Cenomanian Holocryptocanium barbuiPseudodictyomitra pseudomacrocephala, Turonian Alievium superbum, Coniacian Alievium praegallowayiPseudoaulophacus praefloresensis, Santonian Alievium gallowayi with two subzones, the lower Santonian radiolarian zone Alievium gallowayiPseudoaulophacus floresensis and the upper Santonian radiolarian zone Euchitonia santonicaArchaeospongoprunum nishiyamae. In addition, six infrazonal bioevents are recognized: the first occurrence of Holocryptocanium tuberculatum in the Cenomanian, Crucella cachensis in the Turonian, Orbiculiforma quadrata and O. vacaensis in the Coniacian, Neosciadiacapsa diabloensis in the Santonian, Amphipyndax pseudoconulus in the Campanian, and the last occurrence of Pseudodictyomitra pseudomacrocephala in the early Turonian.
