Abstract In Punta Odriozola archaeological locality (San Matías Gulf) grinding stone tools showing different preservation status have been detected. In order to characterize these instruments and to determine their possible function, we have registered the lithic raw materials and the metric characters of the pieces, and we have collected the sediments preserved in their cavities and in their immediate surroundings. Archaeobotanical analysis yielded positive results in one of the cases, in which starch grains of Prosopis sp. were identified. The presence of these particular taxa could be due to the grinding of this plant pods for edible use. In the future, the enlargement of the analysis will allow us to determine if these artifacts were used to process other resources.
