Approaching subsistence activities in the Mesolithic by means of lithic tools: The case of El Collado site (Oliva, Eastern Iberia)

Since its excavation, in the late 1980s, El Collado has been considered a Mesolithic funerary site. Nevertheless, recent studies of the site chronology and other material evidence - excluding the human remains - have indicated more complex dynamics of this site, combining both funerary and habitation uses by Mesolithic communities. First, a Bayesian model of the available radiocarbon dates provides information about the chronological dynamics in the human uses of the site. The model reveals that data are not representative of a single event but rather show the existence of several chronostratigraphic phases. Second, a noteworthy lithic assemblage from the site, which does not appear to be linked to the Mesolithic burials, can be attributed to the Notches and Denticulates Mesolithic facies in Mediterranean Iberia and the Ebro Basin. Technological and use-wear analyses of the lithic tools have been carried out in order to seek new data concerning the subsistence and craft activities performed by the communities that occupied the site. It must be noted that only in few cases similar studies had been applied previously on Mesolithic sites in the area of study. The first results show intense work on hard materials, such as wood, bone or antler, which a priori could lead to this site being considered a not specialized one from the functional point of view. These results are discussed taking into account all the inputs and possible biases due to the nature of the site and sampling carried out in the fieldwork.
