Tooth enamel nitrogen isotope composition records trophic position: a tool for reconstructing food webs
J. N. Leichliter, T. Lüdecke, et al.
This groundbreaking study reveals how the nitrogen isotope composition of organic matter in mammalian tooth enamel serves as an effective record of diet and trophic positioning, even in the absence of collagen. Jeff N. Leichliter and colleagues found significant differences in δ¹⁵Nenamel values, illustrating its promise as a geochemical tool for deciphering the complexities of ancient food webs.
