Rastreando ausencias: La hipótesis del abandono del uso de los recursos marinos en el momento ecuestre en la Patagonia continental

Abstract

During the research on the northern coast of Santa Cruz province it has been noticed a contradiction between the archeological and ethnohistorical data, especially those referred to the 18th and 19th centuries. In fact, the archeological data suggest an intensive use of the marine resources, while the ethnohistorical ones are not related to this activity. To sort out this contradiction it was hypothetically suggested that these resources were abandoned in the above mentioned period. This hypothesis is submitted to tests at two scales: the first scale implies comparing radiocarbon and fauna information collected throughout the area and published by different authors; the second scale is local and consists of analyzing the changes between sites and components close in space to each other before and after the contact. For this last case information from cañadón Giménez, bahía Solano 13 and bahía Solano 16 was used. These preliminar results partially support the hypothesis proposed.
