“…For example, recent research (Mickleburgh and Laffoon 2017) has demonstrated that 'Archaic' individuals from Aruba, where multiple lines of archaeological and bioarchaeological evidence have previously suggested distinct hunter-gatherer subsistence practices and highly marine-reliant diets, also possessed extremely enriched enamel δ 13 C values (−5.3 to −3.9‰). In recent years, strontium isotope ( 87 Sr/ 86 Sr) approaches have also been widely applied to studies of human and animal paleomobility, and artefact provenance studies in the Caribbean (Booden et al 2008;Giovas et al 2016;Hofman et al 2012;Hoogland, Hofman, and Panhuysen 2010;Laffoon 2012Laffoon , 2013Laffoon , 2016Laffoon et al , 2014Laffoon et al , 2015Laffoon et al , 2017Laffoon, Sonnemann et al 2016;Valcárcel Rojas et al 2011). The Caribbean region is particularly well suited to the application of the strontium isotope method owing to the geological diversity (Donovan and Jackson 1994) and hence high degree of variability and spatial pattering of bedrock and bioavailable 87 Sr/ 86 Sr. For this region, both large-scale empirical datasets and spatially explicit predictive models of regional isotope landscapes (isoscapes), of bioavailable 87 Sr/ 86 Sr have been developed (Bataille, Laffoon, and Bowen 2012;.…”
