Fig 7. 1: multifacial multidirectional irregular core (OBS); 2, 4: multifacial multidirectional cores with major unidirectional flaking surface(s) (2: OBS; 4: ASB); 3: multifacial multidirectional orthogonal core (OBS); 5–9: flakes with multidirectional irregular negative scars on the dorsal face (5: ASB; 6–9: OBS); 10–12: flakes with orthogonal negative scars on the dorsal face (OBS); 13–15: core edge flakes with multidirectional removals (OBS).

2, 3: drawings by M. Pennacchioni. 1, 4–12: technological schemes by R. Gallotti. ASB: aphyric to subaphyric basalt, OBS: obsidian. 2, 3: these drawings have been modified after 34. They have been rearranged and integrated with new ones in this Figure, which is for illustrative purposes only.
