Glacially dislocated fossiliferous clay – hitherto called Cyprina clay– and associated Pleistocene sediments are exposed at the northeastern German coast. They were uplifted as glacial rafts from a position of about 30 m below the sea level and incorporated into glaciotectonic complexes of Dornbusch (Hiddensee), Arkona (Rügen) and Greifswalder Oie during the ice advances of the Last Glacial Maximum (LGM). Optically stimulated luminescence (OSL) ages of the fossil‐bearing clay and the overlying glacifluvial/lacustrine successions give insights into Late Saalian, Eemian and Early to Middle Weichselian development of the southern Baltic Sea area. The age data especially support the observation of changing environmental conditions prior to the Eemian warm period as suggested by the fossil record. A high‐arctic brackish fauna documented in a lower reddish‐grey clay is followed by a more boreal brackish‐marine to marine fauna in the overlying olive and/or greenish‐grey clay. This implies conditions of glacial meltwater running to the northwest during the deglaciation phase of the last Saalian Warthe ice advance and inflow of cold marine water from the North Atlantic area along the margin of the Scandinavian Ice Sheet into the Skagerrak and the Kattegat. Subsequently, water with higher salinity entered the mouths and channels of large rivers crossing the southern Baltic Sea area from SE to NW comparable with those of the Oder and Vistula rivers. Eemian Cyprina clay deposits with lusitanian faunal elements are not exposed in the study area but occur in Denmark and northwestern Germany. To distinguish the different facies types and age of the clay, we introduce the stratigraphical term Vitt Formation for the Late Saalian Cyprina clay in NE Germany, comprising Roundstonia, Portlandia and Arctica members – each with characteristic microfossil species.

“…With regard to mollusc fauna that could provide important palaeo‐ecological information, it is significant that the communities found in the marine Holsteinian of Northern Germany consist of relatively few species with boreal characteristics which correlate to a very large extent with the recent fauna of the south‐eastern North Sea. In contrast, for the Eemian interglacial (OIS 5e), for the northern and southern Baltic region there are numerous exotic taxa from the Lusitanian province which extends today from Western France to Spain and Portugal (Nordmann, 1908; Meng, 2021; Meng et al, 2015, 2022). Hinsch (1993) explains this by suggesting that, during the Holsteinian, the transgression took place mainly from the north, while the Eemian Sea probably transgressed mainly from a westerly direction.…”

The bay barnacle Amphibalanus improvisus (Darwin, 1854) has been found in Northern Germany in brackish marine sediments of the Holsteinian interglacial. Whereas the cause of the contemporary distribution of this species is anthropogenic and there is evidence that it has resulted mainly from shipping, the fossil findings demonstrate that A. improvisus had also already reached Europe naturally during the Pleistocene in Europe, probably via the Gulf Stream system of the Atlantic. Today, A. improvisus is considered one of the most successful aquatic invasive species worldwide and it is characterized by a high environmental tolerance. The ingression of the Holsteinian Sea, during the Pleistocene, took place during the climate optimum from the North Sea into the ‘Elbe Estuary’ through the Hamburg region and far to the south‐east into Brandenburg. It has been possible to reconstruct the palaeo‐ecological conditions based in particular on molluscs. Accordingly, environmental conditions ranged from normal marine in the north, via brackish in the transitional area to limnic–fluviatile in the Berlin region. The morphological features of the bay barnacles and their ecological parameters are described here in detail. In addition, we provide a general review of the known Pleistocene Balanidae in northern central Europe.
