Mesolithic sites formation and palaeoenvironment along the White Nile (central Sudan)

The Mesolithic period represents a key stage in the human history of Sudan, but its complexity is not yet fully understood. Since the beginning of prehistoric research in this region, efforts were made to understand Mesolithic site formation processes and post-depositional disturbances. Responsibility for the destruction of most Mesolithic sites\u2019 deposits rests mainly on later use of the ancient mound-like settlements as burial places by Meroitic and post-Meroitic people. Excavations at several sites in the El Salha and Al Khiday areas (White Nile, south of Omdurman) have provided recent progress in our knowledge of Mesolithic living structures in their palaeoenvironmental contexts. Detailed stratigraphic and geoarchaeological investigations enabled us to distinguish, within the sequences identified at excavated mounds, the existence of basal archaeological strata still in situ that had remained unaffected by subsequent anthropogenic disturbances and to understand the functional aspects of several archaeological features associated with Mesolithic living floors. This offers the opportunity to reassess the Mesolithic cultural sequence in the region and reconsider some statements on the economic and social aspects of Mesolithic life and landscape exploitation strategies
