Sažetak
Rich subtropical to warm-water associations of planktonic foraminifera from Middle and Late Eocene sediments were investigated from Venetian basin (north Adriatic Sea) and from the foreland Pazin basin (Istria). High diversity and percentages of planktonic foraminifera (common Acarinina, Turborotalia, Globigerina, Subbotina, and Globigerinatheka) in Venetian basin indicate open ocean environment whilst Pazin basin planktonic assemblages with moderately high diversity and lower P/B ratios imply sedimentation in semi-closed deep-sea environment. Comparison of main foraminiferal groups from both basins indicate that the open ocean Venetian basins surface waters were colder and oligotrophic during P14 biozone than in the smaller Pazin basin due to smaller dimension of the Pazin basin and nutrient supply from the nearby land. During P15 biozone planktonic foraminiferal assemblages of both basins indicate cooler and mesotrophic conditions.
