“…The features described are present over a vast territory extending from north-western Europe to the Near East, including the central regions of the European continent (Goren-Inbar, 1988;Chase, 1990;Golovanova, 2000;Elston and Kuhn, 2002;Ollé et al, 2005;Dibble and McPherron, 2006;Hovers, 2006;Bourguignon et al, 2008;Brenet et al, 2008) (Table 6). Some sites from this area exhibit an early development of Levallois schemes, often accompanied by a trend towards the production of elongated blanks (see for instance: Kozlowski, 2001;Meignen, 1994Meignen, , 1998Moncel, 2001;Révillon, 1995). From MIS 9 onwards, these complexes start to diffuse in the loess and river sequences of north-western Europe (Révillon, 1995) from southern Britain (see for instance Botany Pit, Purfleet, dated from terminal MIS 10 to early MIS 8 or late stage 9/early stage 8, White and Ashton, 2003, and La Cotte Saint-Brelade, layers C-D, dated to 238 ± 35 ka, Callow and Cornford, 1986) to northern France, where the Somme valley sites reveal evidence of Levallois débitage starting around 400 ka (and well mastered use of this technique during MIS 9) .…”
