Summary

Stable isotope analysis of faunal bone can provide valuable information about the environments in which the animals lived. Reconstructing paleoenvironments at archaeological sites permits a better understanding of the factors that influenced their social development and decline. In this poster we present results of stable isotopic analyses (d13Capatite, d18Oapatite, d13Ccollagen and d15Ncollagen) of leporid bone apatite and collagen to investigate temporal changes in environmental conditions at Hohokam site of Pueblo Grande, Arizona, USA. We analyze bone samples from the Gila Bute (725-825 AD), Santa Cruz (825-1000 AD), Sacaton (1000-1100 AD), Soho (1100-1300 AD), Civano (1300-1350 AD), and Polvoron (1350-1450 AD) periods and examine differences between them. Our results demonstrate significant changes in the environmental landscape over time. This study improves our understanding of the culture history of Pueblo Grande, and furthers our knowledge on the social-environment dynamics across the North American Southwest.
