The global marine/terrestrial temperature data from different proxies were collected for the latest Cretaceous (~72-66 Ma), Late Paleocene-Early Eocene (~60-48 Ma), Early Oligocene (~34-28 Ma), and Pliocene (5.3-2.6 Ma). The terrestrial proxies include plant fossils, membrane lipids from soils (MBT/CBT), δ18O of tooth enamel, and clumped isotopes (Δ47) of inorganic and organic carbonates. The marine proxies include membrane lipids of marine sediments (TEX86), UK’37, the Mg/Ca of planktonic foraminifera, clumped isotopes (Δ47) of shell carbonates, and the δ18O of diverse fossils, including fish tooth enamel (phosphate), mollusk shells and fish otoliths (aragonite), exceptionally well-preserved planktonic foraminifera (calcite), and well-preserved rudists and other mollusks (calcite).
