[email protected] a11111 Abstract The rise of stratified societies fundamentally influences the interactions between status, movement, and food. Using isotopic analyses, we assess differences in diet and mobility of individuals excavated from two burial mounds located at the `Atele burial site on Tongatapu, OPEN ACCESS the main island of the Kingdom of Tonga (c. 500 - 150 BP). The first burial mound (To-At-1) was classified by some archaeologists as a commoner’s mound while the second burial Citation: Stantis C, Kinaston RL, Richards MP, mound (To-At-2) was possibly used for interment of the chiefly class. In this study, stable Davidson JM, Buckley HR (2015) Assessing Human 13 15 34 Diet and Movement in the Tongan Maritime Chiefdom isotope analyses of diet (δ C, δ N, and δ S; n = 41) are used to asses paleodiet and Using Isotopic Analyses.
