Prof. Beth Scaffidi and co-authors Tiffiny A. Tung (Vanderbilt U.) and Kelly J. Knudson (Arizona State U.) have just published a article entitled "Seasonality or short-term mobility among trophy head victims and villagers?: Understanding late-life dietary change in the pre-Hispanic Andes through stable isotope analysis (δ13C/δ15N) of archaeological hair keratin and bone collagen" in the Journal of Archaeological Science: Reports. As the title indicates, this study uses isotopic information from human cranial remains to determine whether adults living at the site of Uraca in the Lower Majes Valley, Arequipa, Peru altered their diets in late-life.
