Middle Miocene shark teeth from the southern margin of the Pannonian basin system (Serbia, Central Paratethys)

This paper describes Middle Miocene (Badenian) shark teeth from Serbia and discusses their geographical distribution at other localities of the Central Paratethys. The shark teeth originate from Visnjica (near Belgrade), from Visnjica Clay, or the ?Pleurotoma Clay?. The variety of sharks is very low, but according to these fossils Visnjica is the richest among serbian localities. The sharks teeth reported in the paper belong to the following taxa: Otodus (Megaselachus) megalodon (AgAssiz, 1835), Hemipristis serra AgAssiz, 1835 and Odontaspididae indet. The high diversity of invertebrates (molluscs, echinoids, corals etc.) and other coeval fossil assemblages indicate a warm period (the Middle Miocene Climatic Optimum), which preceded the Middle Miocene Climatic Transition. nema
