Description: | A collection of three knapped microburins, dating to the Mesolithic period between c. 8000 BC - c. 4000 BC (length ranging from 11-21mm; average thickness: 3mm; collective weight: 1.74g). A bulb of percussion and ripples or 'lunettes' are visible on the ventral (lower face) side of the largest piece. Multiple arrises are on all but one piece, with normally 2-4 arrises on the dorsal (upper face) side. In his 2004 publication 'Guide to the Identification, Assessment and Recording of Lithics October 2004, Version 1',page 209, C J Bond describes microburins as 'a by-product of the manufacture of microliths, formed by working a notch into the edge of a blade by an anvil technique. This process will then cause the blade to break obliquely, giving a microburin with a pointed break, 'piquant triedre'. The diagnostic feature is the burin notch or 'facet'. This technology occurs throughout the Mesolithic. However, in the Later Mesolithic with the reduction in blades and bladelets, this determines that the microburin is also reduced in size'. | Source: | Portable Antiquities | Creator: | Johnson, Caroline - Portable Antiquities Scheme | Identifier: | http://www.findsdatabase.org.uk/hms/pas_... | Language: | en-GB | Go to resource |
