Abstract

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.

Highlights

This paper describes Middle Miocene (Badenian) shark teeth from Serbia and discusses their geographical distribution at other localities of the Central Paratethys
Tioned in the literature since the 19th century with This paper refers to the Badenian shark fauna numerous described extinct species (e.g., AGASSIZ, from Višnjica (Belgrade, Serbia) (Fig. 1A, B, C)
Recent research allows the evaluation of their the shark diversity and its distribution along the diversity, as well as the areal and the stratigraphic southern margin of the Central Paratethys during the distribution of these fossils

Summary

Introduction

This paper describes Middle Miocene (Badenian) shark teeth from Serbia and discusses their geographical distribution at other localities of the Central Paratethys. The sharks teeth reported in the paper belong to the following taxa: Otodus (Megaselachus) megalodon (AGASSIZ, 1835), Hemipristis serra AGASSIZ, 1835 and Odontaspididae indet. Описани зуби ајкула припадају следећим таксономима: Otodus (Megaselachus) megalodon (AGASSIZ, 1835), Hemipristis serra AGASSIZ, 1835, и Odontaspididae indet. Tioned in the literature since the 19th century with This paper refers to the Badenian shark fauna numerous described extinct species (e.g., AGASSIZ, from Višnjica (Belgrade, Serbia) (Fig. 1A, B, C). By analysis of the Midanalysis points out that the shark teeth are relatively dle Miocene Serbian localities, the Višnjica fauna aprare in the palaeontological record of the Serbian pears to be the most diverse.
