Sažetak
Micropaleontological analyses of the Middle to Late Eocene deep sea sediments from deep exploration wells in Venetian basin (northern Adriatic Sea) and from land outcrops within Trieste-Pazin basin (Istria, Croatia) revealed differences of composition and faunal characteristics of planktonic foraminiferal assemblages. These differences imply influence of local ecological factors like trophic resources, water temperature, as well as paleogeographical position and water circulation. In Venetian basin typical mid-latitude foraminiferal association dominated by subbotinids and turborotalids indicate slightly lower water temperature, oligotrophic environment and open ocean circulation. On the other hand, the Trieste-Pazin basin assemblages suggest warmer and well ventilated surface water as a result of good comunication with open ocean waters, that were favourable to radiation of symbionts bearing globigerinathekids and muricate forms.
