DESCRIPTION:The recovery of a seed grinding stone from human occupation la
 yers dating to c.31 ka in the Haua Fteah cave on the coast of the Gebel Ak
 hdar massif in northeast Libya sheds new light on the subsistence practice
 s of modern humans in North Africa. Residue analysis recovered a total of 
 15 starch granules that we have identified as belonging to wild cereals\, 
 ten of which are identified as A-type granules of Aegilops spp. (goat gras
 s). Usewear analysis has confirmed the use of the tool as a seed grinder. 
 These findings suggest that the diet of modern humans in the Gebel Akhdar\
 , a region considered a likely refugium during the increasingly cool and d
 rier climates of MIS 3\, included low-ranked but ubiquitous grass seeds. A
 longside the macroplant remains and residue study of the grinding stone fr
 om Hut 1 at Ohalo II\, these results are some of the clearest evidence for
  the processing of grass seeds during the Late Stone Age/Upper Palaeolithi
 c. This study also adds to an increasing body of evidence regarding the pr
 ocessing and consumption of grasses by AMH and Neanderthals. Usewear and r
 esidue studies of grinding and pounding technology in southern Europe and 
 Australia\, indicate that seed grinding should be recognised as well withi
 n the behavioural repertoire of modern humans during the Late Pleistocene.
