Reconstruction of planar and lateral profiles of the best-preserved double-beveled bone tools from Sibudu. The profile reconstruction (thick black outline) is based on complete or near complete specimens found in Howiesons Poort (a–c), Still Bay (e–f) and pre-Still Bay (i,l,p,u) layers. Grey shaded areas indicate the preserved portion of the tools. Letters match those in Fig. 2 where photographs of the archaeological objects are presented. Scale: = 1 cm.
