Early and Middle Holocene paleoclimates in the South Western Desert of Egypt - the world before unification

In the field seasons of 1990 to 2008 the Combined Prehistoric Expedition conducted an extensive archaeological, archaeozoological, archaeobotanical and geomorphological field work at more than a hundred sites in the Nabta, Kiseiba, El Kortain, Gebal El Beid, Gebel Ramlah and Berget El Sheb Areas, South Western Desert of Egypt. The research has helped to develop a long chronological sequence of Late Glacial and Holocene climatic changes in the region. The climatic sequence has been supported by more than 300 14C and OSL assays that permitted to place most of the climatic events in a firm chronological frame.
