MICROLITH
Unique ID: SWYOR-048E21
Object type certainty: Certain
Workflow
status: Published 
A flint geometric microlith of Late Mesolithic date, about 8000 BC - 4000 BC. It is formed on light grey translucent flint. It is trapezoidal in plan and triangular in cross-section. The blade has a double dorsal ridge but is damaged at the proximal right corner so part of this is missing. The left side is retouched with very fine, short, sub-parallel, abrupt removals, particularly at each end and less distinct in the centre of the edge. The microlith is 16.9mm long, 9.8mm wide and 2.5mm thick. 0.37g.
