“…Furthermore, blank production at Aranbaltza II is basically oriented towards the production of blades and bladelets, following the same production schemas seen at classic sites such as Roc de Combe, La Côte and Quinçay [ 21 , 26 ], Morin level 10 [ 34 ], and also evidenced in assemblages such as Labeko Koba [ 27 ], Ekain [ 35 ], and Cova Foradada [ 36 ]. Blade and bladelet production in the regional Middle Paleolithic are very rare, and never formed part of the structural productions for the Mousterian Neandertals [ 37 – 40 ]. Additionally, there are no MTA-B assemblages in the Cantabrian Region [ 41 ], while and backed tools associated with Mousterian assemblages, like the Abri Audi knifes, are very rare in the Northern Iberian Peninsula [ 33 , 42 , 43 ].…”
