The effects of sample treatment and diagenesis on the isotopic integrity of carbonate in biogenic hyroxylapatite.
In most cases, archaeologists attempt to be minimally destructive in their analyses, so the removal of a small sample of tooth enamel is required with the tooth mostly preserved. Thus, their radiocarbon levels mirror those in the changing environment. To determine year of birth, the researchers focused on tooth enamel. This high dependence may be related to a combination of local ecological as well as socioeconomic factors.
