Ecological isotope proxies measured in ancient bivalve shell matrix protein have great promise for paleoecological reconstruction. Compound-specific isotopes of amino acids (CSI-AA) may be an ideal tool for developing paleoecological proxies, as initial work has indicated that CSI-AA is less subject...
