Abstract The distribution of δ13C values from human remains recovered in the eastern Chihuahuan Desert and central Texas demonstrates the existence of at least two distinct coeval dietary populations during the Early and Late Archaic. We employed a novel statistical technique, norma probability plots, to identify distinct dietary populations. δ13C values from one population in the Lower Pecos and Trans-Pecos regions of Texas reflect the long-term use of Chihuahuan Desert C4 and CAM plants. A second group, consisting of all the central Texas individuals and some individuals from the Lower Pecos, depended heavily on C3 plants more common in the Edwards Plateau or in the oak-pine forests in Mexico. The wide range of stable carbon isotope ratios from the Lower Pecos region of the eastern Chihuahuan Desert forces a reconsideration of hunter-gatherer settlement and social organization models proposed for that region. This study highlights the need to conduct more research on hunter-gatherer prehistoric diets and social organization.
