Title |
barbed and tanged arrowhead (ventral) |
||
Description |
English: Flint barbed and tanged arrowhead dating from the Beaker period, from the Late Neolithic to the Early Bronze Age (c.2500-1500 BC). The arrowhead is triangular in plan with curved sides and lenticular in both profile and section. It has low angle retouch on about half of both faces, with fine pressure-flaked retouch on all of the margins. Both barbs are pointed and the tang is wide and slightly longer than the barbs and gently rounded at the base, placing it within the Beaker barbed and tanged arrowhead group Sutton B, Type g, of Green's 1980 classification illustrated in Bond (2004) on page 125, fig.5.111. The arrowhead is made on a tertiary flake of translucent dark grey-brown flint and is not patinated and likely derived from imported flint, perhaps from Beer Head in Devon, and not from local beach flint.
Bond (2004) illustrates two similar arrowheads, from Windmill Hill, Avebury on page 147, fig.5.133, nos.F179-180, which date from the Beaker period, c.2500-1600 BC. |
