Data for: The evolution of terrestrial latitudinal temperature gradient from the latest Cretaceous through the Present

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).本数据集收集了白垩纪晚期（约72~66 Ma）、古新世晚期-始新世早期（约60~48 Ma）、渐新世早期（约34~28 Ma）以及上新世（5.3~2.6 Ma）时期，基于不同代用指标（proxy）获取的全球海洋与陆地温度数据。其中陆地代用指标包括植物化石、土壤膜脂（MBT/CBT）、牙釉质的δ¹⁸O，以及无机与有机碳酸盐的团簇同位素（Δ47）；海洋代用指标涵盖海洋沉积物膜脂（TEX86）、UK’37、浮游有孔虫的Mg/Ca比值、壳体碳酸盐的团簇同位素（Δ47），以及多种化石的δ¹⁸O，这些化石包含鱼牙釉质（磷酸盐）、软体动物壳体与鱼耳石（文石）、保存极佳的浮游有孔虫（方解石），以及保存完好的固着蛤（rudists）与其他软体动物（方解石质）。
