Bidirectional blade technology on naviform cores from northern Arabia: New evidence of Arabian-Levantine interactions in the Neolithic

Abstract

Discovered in March 2015, the sites of DAJ-112 and DAJ-125 in the Al-Jawf province of northern Saudi Arabia consist of a large collection of surface lithic artefacts that can be compared to well-known Pre-Pottery Neolithic (PPN) B technology from the Levant: the two sites include bidirectional blade technology with naviform core preparation and opposed platforms surface exploitation, as well as burin production at a wide scale. Other surface scatters have been identified during the 2013 and 2015 surveys, showing these two sites are not isolated in Al-Jawf, as rather important occurrences of Early Holocene technology have been identified across the region. Although the sites from Al-Jawf are surface occurrences and not radiometrically dated, the finds have proven to be extremely significant, representing a southward incursion of classic naviform cores-based technology, thus expanding the geographical distribution of this technology beyond the Levant. By addressing the lithic evidence from northern Arabia, the expansion and/or influence of PPN populations and cultural elements will be discussed.
