Table 4. Archaeological sample and use wear description and interpretation.

Id	Type	Activity	Macro traces	Micro traces	Traces Localisation	Prehension	Note
RF73	Hammerstone	Core maintenance and overhang abrasion	Isolated striations, chaotic, deep and long; overlapping pits.	Absent	Pits located on short margins; striations on the flat surfaces	Absent	The sample is altered (grain detachment and rounding)
RF127	Hammerstone and Retoucher	Core maintenance and scaled retouch	Small pits, overlapping with associated small striations; linear (half-moon) pits.	The bottom of linear pits is not polished	Pits overlapping located all around the short margin; linear pits located on the two flat surfaces	Yes, in the central area, on the flat surface (rounding of grain, organic film, and patches of polish)
RF67	Retoucher	Scaled retouch	Linear (half-moon) pits	The bottom of linear pits is not polished	Pits located on the two flat surfaces, opposite apices	Absent	Ochre residues; General rounding
RF92	Anvil and retoucher	Marginal retouch; passive anvil	Long, superficial striations with the same orientation, associated with small sub-circular pits; pits with sub-triangular or quadrangular morphology.	The bottom of the striations is not polished	Pits and associated striations located along the apices of the flat surfaces; pits with sub-triangular/quadrangular morphology in the central area on the flat surface	Absent
RF80	Retoucher	Marginal retouch	Circular pits and associated striations on the apical areas of the flat surface	The bottom of the striations is not polished	On the apical areas of one flat surface	Absent
RF138	Hammerstone	Bladelet removal	Flake detachment and overlapping pits. Morphology of the pits is not defined.	Polishing not present	Along the short, opposing, edges	Absent	Alterations, general rounding
RF37	Hammerstone	Overhang abrasion and percussion activity	There are long and deep striations and overlapping pits	Absent	Striations on one of the flat surfaces; and sporadic pits on a long margin	Absent	Alteration due to thermal contact; general rounding
