Abstract:
The application of bone collagen stable carbon and nitrogen isotope analysis to human palaeodietary reconstruction in tropical or arid regions is limited by the overlap in C4 and high marine protein (HMP) consumer bulk collagen 13C values, and the unpredictability of bulk collagen 15N values in regions of extreme aridity. To identify a more precise marine palaeodietary indicator, a range of collagen samples from archaeological faunal and human bone (n=14 and 26, respectively), representing a spectrum of C3, C4 and HMP diets, were selected from coastal and near-coastal sites in South Africa. Samples were subjected to compound-specific stable carbon isotope analysis of their constituent amino acids as trifluoroacetyl-isopropyl (TFA-IP) esters via gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS). It was concluded that 13CGlycine-Phenylalanine values offer considerable potential as indicators of HMP consumption and a valuable substitute for bone collagen 15N values in arid regions where bulk 15N values are unpredictable.
