At Tepek Çiftlik in Cappadocia (~7,100–5,800 BCE), 11 newly identified inscribed obsidian arrowheads bring the site's total to 12. Marks were carved with flint tools — obsidian can't scratch obsidian. One elaborate piece has 20+ strokes forming three squares joined by a line. Published in PLOS ONE by Vin and Guilbeau.
12 inscribed obsidian arrowheads found at 9,000-year-old Turkish Neolithic site

Key facts
- Site: Tepek Çiftlik (also rendered Tuchik/Tuchik Çiftlik) in the Melendiz plain, volcanic heart of Cappadocia, central Turkey
- Settlement dating to roughly 7,100-5,800 BCE, home to early farming and herding communities
- About 740 obsidian arrowheads knapped from the region
- New study identified 11 additional inscribed arrowheads, bringing the site's total to 12 and the central Anatolian total to 54
- Published in PLOS ONE, led by Alice Vin and Denis Guilbeau
- Microscopic analysis revealed deliberate carved marks made by scoring 2-3 times to grind away dark surface and leave a pale line
- Obsidian cannot easily scratch obsidian; experiments indicate carvers deliberately chose flint, which made up barely 1% of stone at the site
- No two marks are alike; one elaborate piece has at least 20 strokes forming three squares joined by a line
- Marks were sometimes cut before, sometimes after, the point was finished
- Marked arrowheads found only in central Anatolia, with loose parallels at Çatalhöyük; found in ordinary houses, not graves or ritual settings
- Katherine Aschmann proposed in the 1980s that these were hunter's marks identifying who made or used an arrow
- Cappadocian obsidian was widely traded, reaching as far as the southern Levant
