It is the goal of this study to better use the D17O of fossilized tooth enamel as paleo-CO2-barometer. We will determine the d17O and d18O of air O2 and mineral standards directly relative to the VSMOW water reference. We will then determine the fractionation in d17O and d18O during respiration. Results will be important input parameters when applying the D17O of tooth enamel as pale-CO2-barometer.
