General measurements (in mm and g) of positives detached during the experiments.

Group categories follow the classification established by de la Mora and de la Torre [13] and expanded by Arroyo [61]. Group 2.3: positives that mimic characteristics of knapping flakes having platforms, bulb of percussion, and impact point; Group 4: irregular fragments without any butt, bulb, or platform; Group 5: positives smaller than 20 mm on which features such as percussive marks, platforms, or impact points are absent.
