Of central importance to palaeodietary reconstruction is a clear understanding of relative contributions of different terrestrial (i.e., C3vs. C4plants) and aquatic (i.e., freshwater vs. marine) resources to human diet. There are, however, significant limitations associated with the ability to reconstruct palaeodiet using bulk collagen stable isotope compositions in regions where diverse dietary resources are available. Recent research has determined that carbon-isotope analysis of individual amino acids has considerable potential to elucidate dietary protein source where bulk isotopic compositions cannot. Usingδ13CAAvalues for human and faunal remains from Zvejnieki, Latvia (8th – 3rd millennia BCE), we test several isotopic proxies focused on distinguishing freshwater protein consumption from both plant-derived and marine protein consumption. We determined that theΔ13CGly-PheandΔ13CVal-Pheproxies can effectively discriminate between terrestrial and aquatic resource consumption, and the relationship between essentialδ13CAAvalues and theΔ13CGly-PheandΔ13CVal-Pheproxies can differentiate among the four protein consumption groups tested here. Compound-specific amino acid carbon-isotope dietary proxies thus enable an enhanced understanding of diet and resource exploitation in the past, and can elucidate complex dietary behaviour.
