Burned by the fire: Isotopic effects of experimental combustion of faunal tooth enamel

Laboratory Assessment of the Impact of Chemical Oxidation, Mineral Dissolution, and Heating on the Nitrogen Isotopic Composition of Fossil‐Bound Organic Matter

“…Substantial calcite decomposition typically begins between 500° and 550°C, although marine carbonates may already become unstable at temperatures between 400° and 500°C due to the presence of magnesium (Hirota & Szyper, 1975). Tooth enamel suffers structural and chemical alteration in response to thermal stress mainly at temperatures above 600°C (Robinson & Kingston, 2020; Shipman et al., 1984).…”
