Human bone carbon Isotope composition

Figure 8.9 Carbon isotope composition of human bone collagen from the lower Illinois Valley, North America. The increase from <513C = —22%0 to —10%o at c. AD 1000 marks the arrival of maize agriculture at the end of the Late Woodland period (van der Merwe 1982). Reproduced by permission of American Scientist.
