“…More specifically, the reduction schemes observed in Atxoste and Peña-14 are identified in other sites with previous occupations. Flake edge reductions for bladelets are very common, as well as unipolar exploitations, mainly frontal, but also semi-tournant on nodules for blades-bladelets, both in the upper and middle Ebro and neighbouring regions-Zatoya (Cava, 1989;Barandiarán and Cava, 2001), Portugain (Aguirre, 2008), Urratxa III (González Urquijo and Ibáñez, 1997), Berniollo (González Urquijo and Ibáñez, 1991), Forcas I ; Parco (Mangado et al, 2005); Balma Guilanyà (Martínez-Moreno y Mora, 2009); Molí del Salt (García Catalán et al, 2013); Cativera (Morales et al, 2013) Cova de la Guineu (García Catalán et al, 2013)-; samples also being present in the Mediterranean region (Roman, 2015;Vadillo, 2018). Reduction sequences on thick endscraperlike cores observed in Peña-14 have also been identified in different sites (Mangado et al 2005;Román 2015).…”
