Abstract: The northern Adriatic Sea supports both typical modern marine benthic associations of animals that live within the sediment and other associations with a Paleozoic ecological aspect, rich in sedentary animals that live exposed on the sea floor. Site-specific information on sediment grain size, deposition rate, currents, nutrient availability, and life habits of animals in the local associations are compared to test several hypotheses about the transition from the Paleozoic to the modern ecosystem. By far the strongest correlations of life habit attributes is with nutrient concentration, supporting the hypothesis that increased nutrient concentration in the sea was important in the change from Paleozoic to modern marine benthic ecology.
