From: CO2 and temperature decoupling at the million-year scale during the Cretaceous Greenhouse
Comparison of the carbon isotope compositions of leaves of the fossil conifer Frenelopsis (δ13Cleaf) obtained for each studied episode with the evolution of the carbon isotope composition of atmospheric CO2 (δ13CCO2) throughout the Cretaceous estimated by Barral et al.16. Envelopes and bar errors correspond to ±1σ.
