Isotope geochemistry

The isotopic compositions of carbon, oxygen and even calcium in dental tissues provide information on the sources of water and food, as well as the physiology of the animal when the tooth is formed.

These isotopic compositions on serial samples of enamel from the apex to the cervix retrace dietary and climatic variations over several weeks to months or even years.
