Addressing the ambiguity between debitage and shaping objectives in the European Late Middle Pleistocene industries: a technico structural analysis of cores and macro tools from sub level TD10.1 of Gran Dolina (Sierra de Atapuerca, Spain)

Résumé

Certain methods of debitage involving increasing degrees of systematization or even predetermination of products app ear as from the end of the European Middle Pleistocene (Mourre and Colonge, 2007; Oosterbeek et al., 2010; Turq et al., 2010; Rubio Jara et al., 2016; Santonja et al., 2016; Di Modica and Pirson, 2016; Mathias et al., 2020). Among them, centripetal debitag e methods, e.g. Discoid or related, are characterised by the management of two convexities around an intersection plane, whose interchangeable roles alternate between the striking and the debitage platforms (Gouëdo, 1990; Boëda, 1993; Mourre, 2003). These processes involve constant regularisation of the piece circumference with an angle that remains secant. The products of these debitage methods are undeniably desired for their morphologies with various functional potentials (thick butt, peripheral cutting edges, lateral backs, etc.). But the real purpose behind these cores production can be questioned, given the potentially functional morphological properties of the resulting edges. A similar ambiguity exists in t he production patterns of the characteristic associated large cutting tools, that have sometimes been defined as 'combined mixed' shaping, reflecting the simultaneous purposes of shaping and small debitage (Colonge et al., 2014). The industry of the sub level TD10.1 of Gran Dolina in the Sierra de Atapuerca (Castilla y Leon, Spain) associates precisely these dif ferent types of pieces, core tools or tool cores, in significant amount. The remains of this level, attached to MIS 10 9, would reflect a base camp with occupations of varying duration (García Medrano et al., 2013, 2014, 2015, 2017, 2018; Terradillos Bern al, 2013; Lombera Hermida et al., 2020). Among the raw materials used, chert is in the majority, but other rocks such as quartzites with more or less fine grains and sandstones are also used for both macro tools and small debitage (Terradillos Bernal and R odríguez Alvarez, 2014, 2017). A technico structural analysis of about 250 pieces of this sub level is conducted according to the techno morpho functional approach that has been developing for several decades in lithic technology (Lepot, 1993; Boëda, 1997; Soriano, 2000; Bonilauri, 2010; Nicoud, 2011; Viallet, 2016; Rocca, 201 6 The resulting technico structural classification aims to gather these artefacts into different groups that are supposed to reflect similar intentions of production, and thus a comm on place within the mental templates of human groups. This preliminary study raises new questions about the overlapping of the debitage and shaping "chaînes opératoires" within the TD10.1 sub level of Gran Dolina, and more broadly of the industries that ma rk the end of the Early Palaeolithic in Southwestern Europe.
