The present study is the first step in the elaboration of a regional base of lithic resources for an area located in the northeastern San Luis province, Argentina. Within this area lies the Estancia La Suiza archeological locality, near the hills of Sierra de la Estanzuela, where prehistoric quarry workshops have been identified. The main objective of this work was to explore the use of the different raw materials by prehistoric groups. The general geological setting of the hills of Sierra de la Estanzuela is described, and a distribution of raw material in the area is proposed. The principal sources of lithic material procurement representing the archeological record were identified, and lithic types were quantified and classified. Finally, the lithic material recovered from the Estancia La Suiza 2 quarry was characterized; the results show that the artifacts correspond to the earliest stages of production. 相似文献

Stable isotopic ratios from archaeological bone collagen are valid palaeodietary indicators, but depend on sufficiently well
preserved molecules and several collagen quality criteria have to be fulfilled (mostly collagen wt%, C%; N%, C/N molar ratio).
For a reassessment of these quality criteria, and a better understanding of the chemical degradation of bone collagen, experimentally
degraded modern bones and 54 archaeological human bones were investigated. In the course of the experimental degradation,
alterations of isotopic ratios were paralleled by altered collagen quality criteria. The contrary was found in the case of
the archaeological specimens. This implies that the commonly used collagen quality criteria may be insufficient and do not
guarantee that stable isotopic values of the gelatine extracts will still represent the original biological signal. 相似文献

The two archaeofaunal assemblages from Haithabu (Viking period) and Schleswig (early Middle Age) belong to the largest such bone complexes ever recovered in Northern Europe. More than 800,000 animal bones were recovered from both sites in the course of the last three decades and investigated by traditional archaeozoological methods. More recently and independently from the latter, stable isotopic ratios of the light elements carbon, nitrogen, and oxygen were analyzed on a total of 440 animal bone finds representing 67 vertebrate species from both sites producing a data set comprising 1,760 individual isotopic ratios. In addition, stable strontium isotopic ratios were obtained from 68 animal teeth and bones of four species. In this paper, an attempt is made to synthesize archaeozoological and archaeometrical data on a larger scale. By becoming familiar with the specific potential of each method, we raise questions concerning not only palaeobiodiversity and palaeoecology of fish and birds in the area, trophic webs, and prey/predator relationships, but also human meat-provisioning, import of animals and animal products, and the reconstruction of hunting areas. This transdisciplinary approach led to an improvement in the quality of our interpretations and the validation of previously confirmed and/or rejected assumptions. It is still too early to expect answers to all these questions, but we are convinced that, in attempting to do so, the potential of coordinating such methods for future research will become evident, and we therefore strongly recommend an intensification of archaeometric analyses of archaeofaunal assemblages. 相似文献
