HOLSTEIN SEA

marine transgression during the Holstein Interglacial Stage of the Pleistocene Epoch (the Pleistocene began about 2,500,000 years ago and ended about 10,000 years ago). The Holstein Sea occupied the North Sea and Baltic Sea basins and deposited marine sediments over a wide area. The fauna of the Holstein Sea deposits shows a change from cold to temperate conditions. The Holstein Sea flooded many land areas; correlations are possible between marine and terrestrial sediments.
