Title |
Neolithic leaf-shaped arrowhead (ventral) |
||
Description |
English: Flint leaf-shaped arrowhead, lozenge-shaped in plan, profile and triangular in section. The arrowhead has been worked on all margins of the dorsal face, but has been more extensively worked towards the distal end, particularly along the left margin. The proximal end has been waisted to be better used for hafting, and has been broken off above the bulb of percussion, on the ventral face.
The flint is a grey brown colour and translucent, and was probably knapped from a local beach pebble. The length to breadth ratio is about 3:2. Bond (2004) illustrates a similar example on page 146, Fig.5.132, No.32, which is dated to the earlier Neolithic. |
