Stable Isotopic Analysis of Carbon and Nitrogen as an Indicator of Paleodietary Change among the Pre-state Metal Age Societies in Northeast Thailand (BAR International)

Using northeast Thailand as a model, this work uses stable isotopes of carbon and nitrogen to infer paleodietary change in subtropical monsoon Asia. It is hypothesized that in northeast Thailand during the pre-state Metal Age (2000 B.C. to A.D. 500) there are distinct differences among the populations during this time period which coincide with human induced environmental changes and developments of alternative subsistence technologies. It is further hypothesized that female and male diets differed, possibly from social circumstances, such as sex related food accessibility. The archaeological skeletal series is from Ban Chiang, Ban Na Di, Ban Lum Khao, and Noen U-Loke. Stable isotope analysis of local flora and fauna provide a baseline for interpreting stable isotope data from human samples for this and future studies of paleodiet.
