Sažetak
Paleoenvironmental analyses based on calcareous nannoplankton and foraminiferal distribution were carried out on samples from locality Bogutovo near Ugljevik. During the middle Miocene, the region was positioned on the southern margin of the Pannonian Basin and the Central Paratethys Sea. The studied section is a sedimentary succesion that is dominated by marine marls with a single limestone package near the middle. Continious ocurences of the calcareous nannoplankton zonal marker Sphenolithus heteromorphus and the absence of Helicosphaera ampliaperta in the middle and the upper part of the section allow placement in Zone NN5. The last occurence of S. heteromorphus indicates that the Zone NN5/NN6 boundary can be placed in the top portion of the studied interval. Using the standard Central Paratethys ecozones for benthic foraminifera, the analysed time interval includes two zones: the early Badenian (Moravian) upper Lagenidae Zone and the middle Badenian (Wielician) Spirorutilus carinatus Zone.
