high density of lithics on the floors of houses near the hearths/ovens --> maybe obsidian was worked nearby, but maybe the material was swept there from a nearby location; traces of obsidian knapping near the ladder entries of houses, obsidian caches were stored in the same location;

the chipped stones were similar to those in Köşk Höyük and Tepeçik Çiftlik (e.g. arrowheads);

In Catalhöyük East there were similar bifacially retouched pieces to Tepeçik Çiftlik, Level 3.

bifacial pieces were provided from the workshops in Kaletepe, Göllüdağ, and Nenezi Daği;

similar projectile obsidian points were found in Pınarbaşı B;
