A thick flint debitage blade, of probable Mesolithic date, 10,000 BC - 4000 BC. It is formed on a tertiary thick blade of opaque mottled tan and brown coloured flint with a small area of cortex on the distal end. It is sub-rectangular in plan, with a slight longitudinal curve. The dorsal face has a double arris. There is a significant amount of edge damage, but it does not appear to be organised retouch. It is 83.1mm long, 27.3mm wide and 13.5mm thick. 38.4g. The surfaces are worn and the flint may have been tumbled in a watercourse.

A flint possible core of possible Mesolithic date, 10,000 BC - 4000 BC. It is a large chunk of yellow cherty flint which is crazed and fractured from exposure to heat or file, making the original form difficult to recognise. Most of the surfaces appear to be natural fracturing, but two may be blade removal scars from a cylindrical core, probably from two opposing striking platforms. The chunk is 34.3mm long, 45.1mm wide and 31mm thick. 46.4g. It could also be a chunk of heat damaged debitage or natural stone.
