Grey-buff semi-translucent flint backed blade fragment. Sub-triangular flake with long angled scalar retouch covering the dorsal side and with a bulb at one corner of the ventral surface. The flat edge opposite the bulb and an immediately adjacent smooth positive hinge fracture may have permitted pressure to be brought to bear on what is now an irregular convex cutting edge. Suggested date: Neolithic, 4000-2350 BC.
