The largest bifacially invasive point in this sample is from Carlton, in the east Kimberley, but no pattern correlating size with geographic location is obvious.
Kimberley points that Aboriginal people recognise as 'early' types include both unifacial and bifacially flaked points, invariably made on flakes.
Excavations at a number of MSA cave sites in the western and southern Cape, South Africa, show that bifacially
worked lithics, typical of the Still Bay, occur below and occasionally within the basal levels of Howiesons Poort assemblages.
It is bifacially
worked to a biconvex cross-section, randomly flaked, but carefully done.
The Guanyindong assemblage is dominated by scrapers and small flaked tools (Zhang 1985; Leng 1992), while the Bose lithics are primarily very large bifacially
flaked cobbles (Huang 1987; Hou et al.
There is a similar range of variation in the retouched tool assemblage, although there are six broad categories of what could be considered recurrent forms (TABLE 2): (i) projectile points and bifacially
worked pieces; (ii) flint daggers; (iii) obsidian mirrors; (iv) large retouched obsidian flake scrapers; (v) pieces esquillees (Tixier 1963: 146); and (vi) `non-formal' retouched blades and retouched flakes.
Handaxes are bifacially
manufactured stone artefacts, predominantly pointed or ovate in shape.
