Sažetak
The Adriatic Carbonate Platform (AdCP), which is one of the largest carbonate platforms during Mesosoic Era of the Perimediterranean region, also comprise a major part of the entire carbonate succession of the Croatian Karst (External or Outer) Dinarides, thick in some places more than 8000 m, and chronostratigraphically ranges from the Middle Permian (or even Late Carboniferous) to the Eocene (VLAHOVIĆ et al., 2005). During the Late Cretaceous the AdCP was characterized generally by shallow-water peritidal depositional conditions, interrupted by two drowned platform events (MORO et al., 2002 ; VLAHOVIĆ et al., 2005). Rudists which throve in such paleoenvironments were elevators, sediment dwelling radiolitids. They are preserved mostly as in situ toppled congregations (ROSS & SKELTON, 1993) which ranges from the smallest bouquets towards cluster and finally the biggest thicket forms within laterally present biostromes representing floatstones to rudstones. Besides this most common appearance in the form of biostromes, in the Cenomanian of Istria at the Premantura locality, radiolitid–chondrodont congregations appear as mound and lensoidal forms.
