Late-glacial and early Postglacial finds of Ancylus fluviatilis from the southwestern Baltic Sea

The small limpet Ancylus fluviatilis is reported from two sediment cores from the south-western Baltic Sea. One of the occurrences, from Mecklenburg Bay, is dated to the late-glacial, corresponding to the Baltic Ice Lake stage of the Baltic Sea. The other occurrence, from the south-western part of the Bornholm Basin, is dated to the earliest Holocene, corresponding to the Yoldia Sea stage. These appear to be the first reports of Ancylus fluviatilis shells from submarine deposits from the Baltic Sea.
