Ulrich Rein
During the last few years it has become possible to make a stratigraphical sub-division of the Older Pleistocene in NW Germany by means of pollen analytical examinations of the Upper Pliocene and old interglacial deposits. As is shown in a plate, the tree tlora becomes progressively poorer from the Upper Pliocene to the Middle Pleistocene.
