"worked stones": fine-grained pebbles without shaping were used as tools --> use-wear on the surface, used to shape and sharpen bone tools or other organic material; pebbles used by rubbing, e.g. as a pottery burnishing tool or in leather tanning operations --> therefore the pebbles had a smooth surface or grooved areas caused by the repetitive friction, or pecking marks from hammering stones (used for direct percussion in lithics technique); coarse ground stone artifacts were common, e.g. mortars, grinding slabs, basins (basalt or rhyolite), pestles, anvils; stone axes: chopper axes, hatchets --> made of limestone or fine grained basalt, which indicates a specialized production and a wide geographical range of raw material procurement; 

Bone industry: needles, punches, spoons, awls, scrapers; few special sculpted artifacts: zoomorphic (some realistic bovids, or other stylized animals), all made of wild animal bones;
