Abstract Foxtail millet (Setaria italica) and common millet (Panicum miliaceum) were important staple crops for the inhabitants of northern China since the Neolithic. The near exclusive consumption of these millets results in extremely elevated bulk collagen δ13C values (~−7‰ to −5‰), which serve as natural isotopic tracers in palaeodiet studies. Here we report individual amino acid δ13C results (δ13CAA) for humans (n = 12) and animals (n = 9) that consumed varying amounts of millets at the Proto-Shang period (2000–1600 BC) site of Nancheng, China. Using established δ13CAA proxies (Δ13CGly-Phe, Δ13CVal-Phe, and plots of δ13CPhe vs. δ13CVal, δ13CLys vs. Δ13CGly-P...
