Abstract: A new integrated biostratigraphic concept of an Upper Cretaceous series near Novi Pazar, Stara Raska region, the Vardar Zone, for Bajevica-Mur and Gradina, is based on the distribution of benthic foraminifers, planktonic microfossils, and calcareous nannoplankton, supported by available information on rudists from Bajevica. The Upper Cretaceous succession in the Stara Raska region is characterized by a transgressive trend. The shallow-water sedimentation was short (uppermost Santonian?–Lower Campanian). Progressive deepening during the Campanian Elevata, or the CC17 and CC18 Nannoplankton Zones, is indicated by successive deposition of shallow-water limestones and lower-ramp hemipelagic carbonates, and then of basinal pelagic sediments.
