A range of Mesolithic and Neolithic sites were recorded in the region, under various designations. ‘Khartoum Neolithic’ sites generally correspond with the ‘Khartoum Variant’, perhaps better understood in terms of Mesolithic occupation in the region. Much of the pottery is quite similar to material known from the Third Cataract region and the Dongola Reach, for example at the Wadi el-Arab and el-Barga sites.
