Abstract

Bioarchaeological studies have grown in sophistication and are now helping test assumptions about island garden agriculture (e.g., palm, cassava, and/or maize) and the relative contributions of marine proteins. Bone and teeth samples from five sites on Barbados and one on Barbuda were processed by the Center for Applied Isotopic Studies, University of Georgia, and data are reported for δ13Cco, δ13Cca, δ15Nco, and δ18Oap. Stable isotope ratios, adjusted ratios, and apatite-collagen spacing correspond with results from elsewhere in the Lesser Antilles. After adjustment, all of the δ15N bone and teeth samples are within the food web range for marine protein resources. Adjusted values for samples from Heywoods, Chancery Lane, Goddard, and Light & Power sites are indicative of a marine diet. Protein models of marine/C4 plants and C3 plants indicate a mixture of plant and marine protein.
