Analyses2
The characterization of Neandertals' diets has mostly relied on nitrogen isotope analyses of bone and tooth collagen. (mpg.de)

Nitrogen1
However, few nitrogen isotope data have been recovered from bones or teeth from Iberia due to poor collagen preservation at Paleolithic sites in the region. (mpg.de)

Results4
Based on the extremely low δ66Zn value observed in the Neandertal's tooth enamel, our results support the interpretation of Neandertals as carnivores as already suggested by δ15N isotope values of specimens from other regions. (mpg.de)
