A. Moro (1) & V. Цosoviц (2) Div. of Geology and Paleontology, Faculty of Science, University of Zagreb, 10000 Zagreb, Zvonimirova 8, Croatia. E-mail: (1) Alan.Moro@public.srce.hr, (2) Vlasta.Cosovic@public.srce.hr The Adriatic Carbonate Platform was a product of intense interaction between biotic and abiotic factors from the beginning in Middle Triassic till its demise in Middle/Upper Eocene. The reaction on enviromental changes of the Upper Cretaceous (Turonian-Santonian) rudist and Eocene larger benthic foraminiferal assemblages from Istrian part of the platform is evaluated. All rudists which appear after the Early Turonian transgression, which is recorded through sediments of foundered platform and represent the beginning of the TST, were elevators which thrived in upper photic zone. Limestones of the late TST-LST were deposited on the inner shelf. In inner shelf environment with shallowing-upward cycles, radiolitids thrived through dense thickets. The genera Durania and Praeradiolites thrived in bouquets which may co-alesce to form thickets at inner shelf environment of the late TST-LST. Their growth depended completely (Durania) or partly (Praeradiolites) on net sediment accumulation. The environment in which Durania and Praeradiolites thrived was subtidal and deep enough to be out of reach of emersion. Within the same depositional environment, these genera were later replaced vertically by Radiolites. Individuals with slim, cylindrical shells, and wide growth lamellae, have full-contact within the thickets in which their growth depended little, if at all, on net sedimentation rate. Complete mutual support resulted in dense packing, which may have prevented possible colonization of the other benthos. Also, Radiolites occupied the shallower parts of the subtidal zone with a commissure rim rising above the sediment surface. Renewed deepening in the late Santonian resulted in outer shelf environment of the next TST. Gorjanovicia, together with rare Vaccinites, flourished after the Radiolites. The visible succession of the Upper Cretaceous limestones are ended sometime at the beginning of the late Santonian, which is marked by emersion. The larger benthic foraminiferal faunas indicate a complex pattern of environmental changes during the deposition of the Eocene sediments. This is marked by succession of different foraminiferal associations, alveolinid dominated association replaced by nummulitid dominated, while association reconstruction was completed by the gradual increasing of orthophragminids in sediments. The highest frequency of orthophragminids and their diversification at the lower limit of the photic zone put them into the position to be only among K-strategists well adapted to such conditions. This introduces another environmental parameter which probably controlled the orthophragminid distribution - the nutrient cline. Decreasing dominance and appearance of taxa common for the outer shelf environments (planktonic foraminifera in particular), indicate the completion of the ecosystem restoration. On the basis of the rudist asssemblages characteristics, it is visible that during Upper Cretaceous in Istrian part of the Adriatic carbonate platform, rudist react on the sea level change with different assemblages, i.e. from radiolitid communities in the shallowest part of the subtidal to the mixed radiolitid-hippuritid communities in the deeper part of the subtidal. Biofacies distribution within the Eocene sediments reveals an overall upward deepening and progressive change from oligotrophic to mesotrophic condition. It seems that orthophragminids in trying to keep pace with deepening of their habitat, became well adapted in environment with reduced light condition (within photic zone) and enhanced nutrient content.
