The temptation to use biogeochemical techniques to resolve issues of paleomigration is evident and well intentioned. Knowledge of radiogenic strontium isotope baselines in a region of interest is a sine qua non of such archaeological studies of paleomobility. Here, we present the first detailed study of baseline 87Sr/86Sr values for the island of Puerto Rico. The high degree of 87Sr/86Sr variab...

This research focuses on reconstructing migration and dietary strategies of individuals in the Iron Age. Elemental analyses from archaeological skeletal remains yield an important perspective on temporal shifts in diet in relation to social and environmental circumstances. The elemental ratio data such as dietary and environmental changes have shed light on crucial issues in archaeology. The ce...
