Calcification temperatures in the Pyrenees were 5 °C higher during the Paleocene-Eocene Thermal Maximum than in the Late Paleocene, and meridional temperature gradients were reduced to 0.7–0.4 °C/degree over 25–75°N, according to an analysis of clumped isotopes in soil carbonates and model simulations.
