barbed and tanged arrowhead (ventral) |

Description |
English: A flint barbed and tanged arrowhead dating from the Late Neolithic to the Early Bronze Age (c.2500-1500 BC). An equilateral triangular in plan, lenticular in profile and in section: length 21.2 mm, barb width 21 mm, thickness 4 mm and weight 1.35 g. The flint is fine textured and dark brown in colour. The arrowhead is made on a tertiary flake, with no cortex remaining. The lateral margins have been retouched by the removal of many small pressure flakes on both the dorsal and ventral surfaces, producing the sharp edges of the arrowhead. The proximal end has been altered by the removal of two notches, which have then also been carefully retouched by the removal of more pressure flakes, to produce the two barbs and the central tang of the completed arrowhead. The tang is square and both barbs are rounded although one is narrow and slightly pointed. Small unworked patches, revealing evidence of the conchoidal fracturing on the surface of the original flake, remain on both surfaces, resulting in a thicker proximal end. The arrowhead is undamaged, suggesting that it may not actually have been used for its intended purpose. Barbed-and-tanged arrowheads were produced from the Late Neolithic, through the Beaker period and were widely used throughout the Early Bronze Age.
Bond (2004) illustrates a similar shape of barbed and tanged arrowhead where the barbs are not as long as the tang on pages 125 & 147, figs.5.110 & 5.133, Sutton Type B (after Green 1980), letter g and no.F177, which is dated from the Beaker period (c.2500-1700 BC in Cornwall). |
