Title |
A single piece of secondary flint debitage of unknown date, probably late Neolithic to Bronze Age. |
||
Description |
English: A single piece of secondary flint debitage of unknown date, probably late Neolithic to Bronze Age. A striking platform and point of percussion are visibly present on this flake. The pronounced bulb of percussion and well defined conchoidal ripple marks indicate hard hammer production. The dorsal side has a pronounced concave recess at the proximal end indicating that a flake had been removed before this one.
Recortication has started on the striking platform, ventral and dorsal face. This recortication is present within the concave proximal zone on the dorsal side, and distal c. two-thirds of the ventral surface (everywhere on the ventral face excluding the bulb of percussion). Cortex remains along the full length of the right mesal side when viewing the flake from the ventral face (left when viewed from the dorsal side). The distal half of the mesal side with cortex remaining, on the ventral face edge, has short abrupt or crossed-abrupt scaled retouch unless this is the result of unintentional damage. The distal two-thirds on the ventral face edge, on the mesal edge with no cortex present, has short abrupt or semi-abrupt scaled retouch unless this is the result of unintentional damage. This flake weighs 18.37g, has a length of 53.8mm, width of 34.8mm and maximum thickness of 8.6mm. |
