It might not look much, just a shard of dark coloured stone, but this is, in fact, a Mesolithic microlith, a small piece of Portland chert that has been deliberately fashioned into a sharp barb, possibly to be used as part of a fishing spear. I have been hunting for a suitable microlith ever since I saw the one from the Culverwell site on the Bill. When you look up close, you can see that all of the edges have been worked. Its maker had a clear idea of what he, or she, was doing, and all this many thousands of years ago. To see such handiwork, and on this scale, is humbling. This microlith brings with it both wonder and a sense of calibration. Thanks Nancy, Nicole and Gareth for all you help with sourcing this.
