The role of the Palaeogene Adriatic carbonate platform in the spatial distribution of alveolinids

Based on studies of numerous stratigraphic sections from the Palaeogene Adriatic carbonate platform, biosedimentary zones (BioZ 2, BioZ 3.1, BioZ 3.2 and BioZ 4) were determined, and each zone is characterized by specific alveolinid associations.
