In the Schoningen open-pit lignite mine (Northeastern Lower Saxony, Germany),Tertiary strata are unconformably overlain by Quaternary sediments and soils of Middle and LatePleistocene and Holocene age. The complex Pleistocene sequence contains a number ofinterglacial and interstadial deposits and soils and is of scientific importance for Late MiddlePleistocene stratigraphy of Central Europe and because of archeological evidence of early humanoccupation by Home erectus. There is evidence of four interglacials younger than the third-lastglaciation (Elsterian). The classical Holsteinian is followed by the newly discoveredbiostratigraphic unit Reinsdorf, an interglacial complex which contains archeological horizonswith wooden artifacts. Based on paleoecological fauna and flora data, the lithological setting andpreliminary age determinations, the Reinsdorf Interglacial likely correlates with marine isotopestage 9 and the Holsteinian with stage 11.
