Summary: New stable isotope data (δ 13C and δ 18O) are presented of well-preserved foraminifera extracted from impermeable clayey sediments from the Middle and late Eocene (DSDP Site 523, Angola basin, S Atlantic), and from the late Cretaceous of Tanzania, the Adriatic and Mexico. The results indicate that tropical sea-surface T were > 28°C during the late Cretaceous-Eocene.
