Sažetak
Transitional beds represent the transition from a shallow-marine environment to a basin setting where turbiditic events produced an impressive sedimentological succesission in terms of thickness and textures. Two phases are recorded: the first phase is known as sedimentation of "Marls with crabs" and the secondphase produced "Globigerina Marls". The unit named " Marls with Crabs" is characterized by co-occurences of larger benthic (orthophragminids and "operculinids" and planktonicforaminifera with decapod crustaceans. We compared the orthophragminid and planktonic fauna from crustacean-bearing sediments from two groups of sections: one located in the northwestern part of the AdCP (Istrian sections: Lutetian age) and the other from the central part (Hvar Is.: Bartonian age), in order to see the species composition, test morphologie and paleoenvironmental needs.
