Upper Cretaceous planktic foraminiferal biostratigraphy

Studia Universitatis Babes-Bolyai, Geologia, 2017
A high-resolution biostratigraphical zonation based on planktic foraminifera is developed for the Upper Cretaceous. It consists of twenty-five biozones defined with the aid of serial and coiled planktic foraminiferal taxa and presents the highest resolution developed with planktic foraminifera for this Series.
