Pleistocene sites in southern Yemen

In the autumn months of 1992 a small team conducted an archaeological survey in southwest Yemen in search of Pleistocene sites dating back to the early colonisation of the Arabian peninsula. The survey focused on those escarpments and terraces with exposed Pleistocene sediments. The team discovered thirty-seven sites, most of them multicomponent, with sixteen having a pebble-tool industry called Mode 1 and twenty-seven with a bifacial industry called Mode 2. Both industries were represented side by side on some sites. These thirty-seven sites, together with others found in northern Arabia and eastern Yemen, contribute to the growing recognition of a Pleistocene occupation of the Arabian peninsula.
