Convex pieces (i.e., lunates) are also present, but relatively rare. Equally noteworthy are the other early chipped stone types which do not occur in the Hallan Cemi chipped stone assemblage. Specifically, characteristically Natufian-type backed and truncated blades are completely absent, as are all other distinctly Natufian chipped stone tool types. \r\nThe nearest sources for obsidian, a valued raw material for the manufacture of chipped stone tools at Hallan Cemi, are in the Lake Van and Bing\u00f6l regions, both ca. 100 km away to the northeast and northwest respectively. Despite these distances, obsidian accounts for 58% of the chipped stone pieces at Hallan Cemi and material from both sources is present at the site. \r\nThe author doesn't describe the lithics in particular, but only mentions them in socio-political and economical context.
