The stratigraphy of the Serbian Pleistocene Corbicula beds

In Serbian records, the most important locations of the Pleistocene Corbicula beds are in the south-eastern part of the Pannonian Plain, which corresponds to the lowland river valleys of the (paleo) Danube, (paleo)Sava and (paleo)Tisza, and the western margin of the Dacian realm. Pleistocene Corbicula beds were formed as warm stage fluvial (and palustrine) deposits, and they are climate-lithostratigraphic units. Pleistocene Corbicula beds are younger than Upper Paludina beds (defined as the lower part of the Lower Pleistocene) in the Pannonian realm or the Romanian stage in the Dacian realm. According to the molluscan assemblage, palaeogeographical features and other paleontological contents (vertebrate fauna, ostracods), they are older than the Upper Pleistocene. According to the reference data and the composition of the molluscan assemblage, the V. boeckhi Horizon has been identified as a biostratigraphic unit. Fortunately, the V. boeckhi Horizon can be adopted to the Serbian climato-lithostratigraphy model of the fluvial warm stages and represents the lowermost part/subunit of the Pleistocene Corbicula beds of Lower Pleistocene age.
