Fig 4. Incremental dentine carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope ratio profile of KUW 4 a juvenile who died ~13 years of age when the tooth was still mineralising.

It shows the opposing covariance famine pattern age 4.5 to 7 years followed by the maize pattern 8.5 to 13 years. Analytical uncertainty is shown at +/- 0.4‰ (2sd).
