Data for: Revisiting the equable climate problem during the Late Cretaceous greenhouse using paleosol carbonate clumped isotope temperatures from the Campanian Western Interior Basin, USA

These files contain data and supplementary data including stable and clumped isotope replicate data for paleosol carbonates collected from the Late Cretaceous Kaiparowits (Utah, USA) and Two Medicine (Montana, USA) formations. Also includes reconstructed warmest month mean temperatures, mean annual range in temperature, and estimated coldest month mean temperatures for the two study areas.
