barbed and tanged arrowhead (dorsal) |
||
Description |
English: A flint barbed and tanged arrowhead. Triangular in plan, plano-convex in profile and in section. Made on a secondary flake of fine-textured, medium-brown flint with a small patch of cortex remaining on the dorsal face. A series of conchoidal ripples are clearly visible at the distal end of the ventral face although the striking platform and bulb of percussion and have been lost by the deliberate snapping off of the proximal end of the flake, to produce the desired triangular shape. This complete edge and the adjacent distal edge have then been blunted from the dorsal face by the removal of many small pressure flakes. The arrowhead may have been made into a transverse (but without the transverse flake to create the bevelled edge) or triangular arrowhead initially, and was subsequently modified by the removal of two symmetrically-placed notches on the un-retouched edge to produce a crude barbed-and-tanged arrowhead. A third notch, on the 'snapped' edge of the left margin of the dorsal face, opposite one of the notches on the lower right margin of the dorsal face, may have served to haft the transverse arrowhead at its base, if it was still used in this allignment, shown in the second image, which is more symmetrical and therefore aerodynamic.
Butler (2005) describes similar triangular arrowheads, which occur in later Neolithic and possibly Bronze Age assemblages, on page 160, final paragraph and illustrates one on page 161, fig.67, no.1. He comments that some were possibly intended as blanks for barbed-and-tanged arrowheads. Bond (2004) illustrates a similar transverse arrowhead on page 142, fig.5.128, no.F133, which is dated from the Later Neolithic period. Keene (1999) illustrates transverse arrowheads with sloping rather than angled distal ends from Watch Hill in Cornwall, on page 5, fig.9, no.2, and Salcombe Hill in Devon, on page 66, fig.3, nos.29, which are dated from the Later Neolithic period to the Early Bronze Age. |
