Tepecik-Çiftlik arrowheads reveal unexplained Neolithic markings

Archaeologists have identified 11 additional obsidian arrowheads featuring deliberate, unexplained incisions at the Neolithic settlement of Tepecik-Çiftlik in central Anatolia, Turkey. These nearly 9,000-year-old artifacts bring the total number of marked arrowheads found at the site to 54.

Microscopic analysis reveals that the marks were made using flint, a material that is relatively rare in the settlement's debris. Because obsidian cannot be effectively scratched by other obsidian, researchers concluded the incisions were intentional rather than accidental damage. The markings consist of repeated strokes that vary in form and position, with some arrowheads featuring one, two, or three aligned lines.

While the obsidian itself was a highly valued material traded across hundreds of kilometers, the specific practice of marking these tools appears unique to Central Anatolia. Researchers suggest the engravings could have served various purposes, such as identifying a hunter's equipment, signifying social status, or acting as symbolic decorations, though the exact cultural meaning remains unresolved.
