Figure 4
From: A 36,200-year-old carving from Grotte des Gorges, Amange, Jura, France
Traces of grooving. Close-up of the notches arranged radially around the concavity (a) and those present between the protuberance and the left edge of the figurine (white arrows) (b). These modifications result from the to-and-fro movement of an elongated edge. Parallel micro-striations are present inside the notches and suggest the use of a soft, quickly worn cutting edge, such as a limestone flake (c,d). Scales (a,b) = 1 mm.
