A flint lithic implement, a probable chopper of Mesolithic date, about 9000 BC - 4000 BC. It is formed from a secondary chunk ofmottled light grey flint which is opaque and has one face covered in cortex. There are also large chalky inclusions. It is sun-rectangular in plan, wedge shaped at one end, and sub-rectangular in scross-section. There are at least five removals from the tapering end. These are struck towards the main body of the object and form a unifacial working edge (as distinct from a chopping tool which is bifacial). Onlt the one end of the tool is worked. Examples of choppers can be seen on page 29-30 of Palmer (1977) Mesolithic Cultures of Britain. They differ only in having been formed on natural cobbles or pebbles. Though choppers are often associated with Paleolithic cultures, they are also found in Mesolithic assemblages which is much more likely for this findspot. The tool is 86.8mm long, 51.4mm wide and 61mm thick. 295g.
