The middle miocene (Badenian) holoplanktonic mollusks (Euthecosomata - Pteropoda) from Serbia, central paratethys

Abstract

The present paper deals with holoplanktonic gastropods (Pteropoda) from the Middle Miocene (Badenian) deposits of Serbia. The material for the present study comes from three localities at the southern margin of the Pannonian Basin (Central Paratethys): Konjarnik (greater center of Belgra de), Sumijevac stream near Koceljeva (western Serbia), and Radljevo (Kolubara Basin, central Serbia). A total of four taxa were recorded and their stratigraphic value is discussed. Two taxa were identified to species level: Vaginella austriaca KITTL, 1886, belonging to the family Cavoliniidae GRAY, 1850 (1815), and Limacina valvatina (REUSS, 1867)?, from the family Limacinidae GRAY, 1847. Four specimens could only be identified to genus level (Vaginella sp. indet. and Clio? sp. indet.). The specimen of Clio? sp. indet. is possibly the first find of the genus Clio in Serbia. Here presented records of the genera Vaginella and Clio? from the late Badenian (NN6 nannozone) modify the insight into their paleogeographical distribution in the Middle Miocene of the Central Paratethys.
