. Belgrade area is a region of high paleobiodiversity, being ranked among the best known in Serbia. The prominent position among a number of Middle Miocene (Badenian) fossiliferous sites in the vicinity of Belgrade (southern Pannonian Basin, Central Paratethys) are occupied with sediments of Rakovica stream, also known as “Rakovica sands”. Here, the integrated evidence based on new fossil findings of calcareous nannoplankton, foraminifera and molluscs assemblages, allows the stratigraphic revision of the clastic facies of the Rakovica succession. Based on the studies of lithological composition,Ammo- niahigh viennensis paleodiversity molluscs faunaBorelis and haueri local palaeogeographical setting, it can be concludedSphaenolithus with reasonable heteromorphus certainty that deposits of Rakovica stream en- titled “Rakovica sand” represents a sandstone of the shallow marine (littoral) environment duringd RBigny Lower Badenian time.
