Maya Marine Subsistence: Isotopic Evidence from Marco Gonzalez and San Pedro, Belize

Abstract

AbstractThis article presents stable nitrogen and carbon isotopie analyses of diet at the Maya sites of Marco Gonzalez and San Pedro, Belize. This study, which provides important insight into social organization, trade, and subsistence economy for the Postclassic and Historic periods (ca. A.D. 900–1650), also expands our understanding of the distribution of stable carbon and nitrogen isotopes within coral reef food webs off coastal Belize. Marco Gonzalez and San Pedro represent the first documented ancient Maya populations whose diet consisted mostly of marine resources with a minimal reliance upon maize. Although these sites do not appear highly stratified, and there are no dietary differences between sexes or status, the inhabitants of Marco Gonzalez incorporated more mainland-terrestrial animals and maize into their diet than the people of San Pedro. This finding supports the postulated roles of these two settlements, where Marco Gonzalez had trade ties to the mainland site of Lamanai and San Pedro was a small fishing village.
