Comparison between the experimental and archaeological use wear and their distribution.

(a) Experimental striations (10x) related to the overhang abrasion, localised (b) on the flat surface of the pebble; (c) archaeological striations (10x), localised (d) on the flat surface of the sample; (e) experimental pits (15x) related to core maintenance/bladelets removal, with sub-oval morphology, localised (f) around the short edge of the pebble; (g) archaeological pits (10x) with sub-oval morphology, (h) localised around the short edge of the sample; (i) experimental pits (40x) related to scaled retouching, with linear (half-moon) morphology, rough bottom, localised (l) on the apices of the flat surface; (m) archaeological pits (40x) with linear (half-moon) morphology, rough bottom, localised (n) on the apices of the flat surface; (o) experimental pits (20x), related to the anvil used for the flakes detachment, with sub-triangular morphology, localised (p) in the centre of the pebble; (q) archaeological pits (20x), with sub-triangular morphology, localised (r) in the centre of sample; (s) experimental circular pits associated with the striations (20x), related to marginal retouching, localised (t) on the apices of the flat surface with oblique orientation; (u) archaeological circular pits and striations associated (20x), localised on the apices of the flat surface with oblique orientation.
