English: Chert flake, semi-circular in plan, rectangular in profile and section, which appears to be a struck piece but with no secondary working. There is a notch half way down the right margin of the ventral face, which may have been used as a graver, but may also be accidental. The profile of the flake suggests it may have been a core tablet or a core platform rejuvenation flake, as it has several straight sides which could the beginning of flakes taken off this original platform. The flake is very water worn so that it is difficult to identify the material (Rosemary Stewart pers comm). The colour of the chert or flint is a mottled orangey-brown with red marks from iron staining on the surface. The length to breadth ratio is about 2:1.

Bond (2004) illustrates a graver on page 107, Fig.5.91, No.107, which is dated from the Early Mesolithic, and a core tablet on page 110, Fig.5.94, No.L7, which is dated from the Later Mesolithic.

Nick Ashton (Curator of the Palaeolithic Collections at the British Museum) has suggested that it is part of a much larger flake as it has many flake scars from several directions, hit with a hard hammer (such as a pebble) and then rolled in river gravels so it is stained and worn, suggesting it is earlier rather than later in date. Possibly from a Levallois flake or hand axe, which would date from around 250,000 to 40,000 BC.
