The section spans the Priabonian and lower Rupelian stages (~37–33 Ma), including the Eocene–Oligocene Transition (EOT) and the Early Oligocene Glacial Maximum (~33.65 Ma). Stable isotope measurements (δ¹³C and δ¹⁸O) were used to document paleoenvironmental and hydrological changes across the record. Stable isotope (δ¹³C, δ¹⁸O), meteoric water δ¹⁸O, and clumped isotope (Δ47) data plotted alongside the stratigraphic log of the Büyükteflek section https://download.pangaea.de/reference/140193/attachments/stable_and_clumped_isotopes_log.png 34.33981 34.33981 39.66181 39.66181 34.33981 39.66181 216.0 324.0 vertical profile European Research Council ERC https://erc.europa.eu https://doi.org/10.13039/501100000781 101043268 ERC DISPERSAL Buyukteflek_section Büyükteflek 39.66181 34.33981 Anatolia, Turkey Outcrop sample OUTCROP 168 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ Stable isotope analyses (δ¹³C, δ¹⁸O) were performed on 23 calcite-dominated pedogenic carbonate powders using a Thermo 253+ mass spectrometer coupled to a Thermo Kiel IV device (Dual Inlet mode) at CEREGE (Aix-Marseille University). Sample powders (80–120 µg) reacted with 105% phosphoric acid at 70°C. Values are reported relative to IAEA-603 in the V-PDB reference frame. Full analytical details are provided in Supplementary Text S1 of Botté et al. (preprint).
