Broken blade |

Description |
English: A group of debitage which is probably of Neolithic, mainly Early Neolithic date with some possibly Mesolithic material. Total weight 33.72g.
Nine unmodified waste flakes (five secondary, four tertiary), all in mottled mid-dark grey flint with paler grey inclusions. Three are broken, with distal ends absent. Some exhibit evidence for core-edge preparation and all are relatively thin and elongate with negligible or weakly formed bulbs of percussion suggestive of use of a relatively soft percussor. As such they are (as a group) unlikely to post-date the earlier part of the Neolithic. All are unpatinated and in moderately sharp condition. Two undiagnostic broken waste flakes: one has resembles the proximal end of a relatively large, well-made blade or blade flake (although most of the flake is absent) made in mid- to light grey mottled flint. The position of the break relative to the flake as a whole seems unusual, and the break-facet possesses a small, weakly-defined bulb on the ventral side, which can sometimes be indicative of deliberate bipolar breakage on an anvil-stone (albeit that modern rotary-harrowing may achieve the same effect). The flake is otherwise unmodified. It is unpatinated and in moderately sharp condition, and likely to be of Neolithic (rather than later) date. The second flake is made on dark brownish grey flint and exhibits many of the characteristics of the nine other waste flakes listed above, other than that it is markedly incurved to a break at its distal end, and its surface is weakly patinated mottled blue-white. There is some post-depositional damage exposing the original colour of the flint. Not closely dateable. One secondary blade, broken, distal end absent, made on mottled mid- to light grey flint with two patches of cortex/sub-cortex. Parallel-sided with a trapezoidal cross-section. The bulb of percussion is diffuse and the striking point is marked by ‘lipping’ indicative of use of a relatively soft percussor. There is also evidence for core-edge dressing on the dorsal surface. Unmodified. Unpatinated and in moderately sharp condition. |
