Social identities and isotopic analyses of the burials from the archaeological site of Ucanal, Petén, Guatemala
With the advances in isotopic analyses over the last two decades, scholars working in the Maya area have come to realize that Pre-Columbian people were much more mobile than previously considered, even though many were sedentary agriculturalists with large urban centers. Isotopic analysis of strontium and oxygen of human teeth enables us to identify the presence of migrants since they reflect geochemical and climatic variability of where a person lived as a child. Twelve burials from the archaeological site of Ucanal, in the Petén region of Guatemala, were analyzed for strontium and oxygen isotopes. In addition, a strontium baseline study of faunal remains was undertaken to identify typical values for the Ucanal region. Out of the twelve burials, three individuals were identified as likely foreign-born. Interestingly, they underscore two different ways in which foreigners were implicated in their newly founded homelands. Together with analyses of the human remains and burial contexts, the isotopic results highlight potentially hostile treatment in the form of human sacrifice or potentially reverential treatments in the form of a cult of the ancestors in which foreign peoples were remembered as important founding ancestors.
