Functional Interpretation of unmodified lithics materials from the middle Paleolithic site of Jarama VI (Guadalajara, Spain)

Jarama VI (Guadalajara) is a Middle Palaeolithic site in which the abundant presence of pebbles and lithic plaques no knapped stands out. The geological and sedimentological hypothesis is that they were contributed by hominids. In order to know if these manuports were used by Neanderthals, we have developed a specific experimental program that attempts to validate the use-wear analysis study of archaeological pieces. We have collected pebbles and plaques from the surroundings of Jarama river, which we have used them in active and passive works. To answer these questions, a specific experimental program has been developed in which some bases similar to those studied have been used as (1) retoucher tool, (2) process bones, (3) work with vegetable fibers, (4) crush ocher, (5) opening of hard-peels fruits and (6) soft-peels fruits. The comparison of the use-wear analysis has allowed us to propose hypotheses about the accumulation of manuports and their use
