Les isotopes de l'oxygène préservés dans l'émail des dents
Oxygen isotopes in dinosaur teeth were used to infer CO2 concentrations in the atmosphere during the Mesozoic Era. Given primary productivity levels similar to today, late Jurassic CO2 levels were four times higher than pre-industrial levels. In PNAS: https://t.co/wP1qyiuUm8 https://t.co/FbZFprUN18
