Title |
Late Mesolithic to Early Iron Age chert microburin - detail of distal working |
||
Description |
English: Late Mesolithic to Early Iron Age chert microburin. It has been formed on a tertiary piece of black chert debitage. There is wear gloss on most of the chert. The burin has been formed at the distal point with the removals creating a point 2mm high. A small area of low angled, scaled, semi-invasive retouch to one of the distal shoulders has produced a notch that could also be utilised as a tool. There is a series of abrupt parallel removals at the proximal end,probably to make it easier to use, and to apply pressure in particular. Probably dates to between c7000 and c400 BC, probably Late Mesolithic to Early Neolithic (c7000 to c3500 BC) as the majority of burins of that period in the locale are either on existing tools or microliths or micro-debitage.
The length is 11mm, width 8mm, thickness 5mm, and the mass 0.50g. |
