Further south, the Ksar Akil Phase 3 assemblage (≈layers XIII-XI of the 1938 excavation) is, like Kostenki 17/II, characterized by Upper Paleolithic blade/bladelet production and is dominated by burins, including multifaceted burins on truncation (Bergman, 1988;Williams and Bergman, 2010 Mellars, 2006b;Demidenko, 2012;Kadowaki et al, 2015).
