The quantitative study of microfossil communities from the Late Badenianmarls at the Sveta Barbara locality (eastern Medvednica Mt.) enabled reconstruction of three different palaeoenvironments: middle shelf, outer shelf and upper bathyal. The dominant factors influencingthe distribution of biota were the deepening of the depositional basin and fluctuations of the oxygenation rate. The outer shelf biota existed under conditions of decreased oxygen levels in bottom water, compared to communities from the middle shelf and upper bathyal environments.
