Remnants of several cultures have been found since the mid-2000s on a large-scale archaeological rescue excavation at the borders of Alsónyék - Bátaszék, SW Hungary. Partial processing of the malacological material of Starcevo culture from the so-called Bátaszék-Mémökségi Telep has been carried out in recent years at the Department of Geology and Paleontology, University of Szeged. Following the taxonomic identification, heights and widths of the shells were determined, then the size distribution and the geochemical analysis were implemented. Geochemical results show that specimens were collected in a different hydrodynamic environment compared to the current conditions of the river Danube. Based on the samples, two periods can be separated, one with flood and high water velocity and one with a more stable conditions after the flood events. Similar results can be found at different non-Danubian archaeological sites with the same ages
