Bioarchaeology of Bronze and Iron Age skeletal finds from a microregion in Central Mongolia

摘要

This paper gives a state of the art report of an ongoing interdisciplinary project on bioarchaeological research on cemeteries in the Upper Orkhon valley, Central Mongolia, in particular at the Maikhan Tolgoi site. The archaeological focus is on the investigation of the development, use and transformation of a ritual landscape in the course of the Bronze and Iron Age. The contribution of physical anthropology is an osteological and archaeometric analysis of the human inhumations with regard to life-style and subsistence economy. A specific topic relates to the emergence of the first mounted nomads in the region. Macro- and microscopical inspection of the skeletons excavated to date reveal that males, females and children had been buried at this exceptional cemetery, and that many of the adults died at a conspicuously advanced age. Palaeodiet was reconstructed by stable carbon and nitrogen isotopes in bone collagen, followed by an isotopic sourcing. We show that freshwater fish was consumed on a regular basis, and that the demands of protein and carbohydrate were largely covered by secondary animal products. First analysis of stable strontium and oxygen isotopes in bone apatite suggests a considerable catchment area of the burial site.
