Radiocarbon and the Stable Isotope Chemistry of Grand Gulch Basketmaker II Burials: Age-Based Dietary Patterning and Geolocation.
The stable isotope chemistry of 149 directly dated Basketmaker II burials from the Four Corners region of the American Southwest indicates relatively heavy reliance on maize and low animal protein intake. Sex and age patterning reveals differences in adult male versus female diets and distinguishes adolescent diets from those of adult males. Hydroxyapatite oxygen isotope values effectively sort individuals relative to the latitude and elevation of burial sites and are further used to clarify the origins of a subset of poorly provenienced remains, thought to be from Chaco Canyon. Grand Gulch Basketmaker II burials date to a two sigma range of 415 BC-AD 322, contemporary with Black Mesa Lolomai Phase occupations and post-dating the March Pass, AZ, White Dog Phase.
