Sažetak
In the Cenomanian shallow-water carbonates of Northwestern Istria five biostratigraphic zones have been established:
CEN-1 Ovalveolina maccagnoae and Sellialveolina viallii biozone in the early Lower Cenomanian;
CEN-2 O. maccagnoae to Chrysalidina gradata interval zone in the late Lower Cenomanian;
CEN-3 C. gradata biozone in the early Middle Cenomanian, locally subdivided into two subzones:
CEN-3a C. gradata and orbitolinids (lower part)
CEN-3b C. gradata without orbitolinids (upper part);
CEN-4 C. gradata and Broeckina (P.) balcanica biozone in the late Middle Cenomanian, and
CEN-5 C. gradata, B. (P.) balcanica and Vidalina radoicicae biozone in the Upper Cenomanian.
