Materials and methods: This study reports stable isotope analyses on apatite bone samples of 139 humans, 48 mammals, and 43 fish from the Al Khiday archaeological sites in Sudan. The bones belong to four archaeological periods: pre-Mesolithic, Mesolithic, Neolithic, and Meroitic. Data were processed statistically. Results: A significant difference exists between the pre-Mesolithic and Mesolithic mean δ18Ow value and the mean of the modern Nile. The mean δ18Ow values for the Neolithic humans and bovids are very similar and more positive than the mean values of Mesolithic mammals and Pre-Mesolithic humans. The water ingested by Meroitic humans is enriched in 18O in respect to the water ingested by the Neolithic population. There is a separation in the δ13C diet values between the pre-Mesolithic humans and Mesolithic mammals group and the Neolithic humans, Meroitic humans, Neolithic mammals, and the modern mammal group. Discussion: The climate became warmer and more arid from the pre-Mesolithic/Mesolithic to the Meroitic period. The environmental conditions influenced the strategies of subsistence and, in particular, the changes occurring from the pre-Mesolithic to the Neolithic can be considered contemporaneous to the transition from hunting-gatheringfishing to cultivation-herding.

New high-resolution d13Corg of the Zumaia section ()23.8 to )28.8&) confirms the position of the Carbon Isotope Excursion and enhances the distinction between the different steps of the CIE ⁄PETM event. According to new magnetic susceptibility data and detailed cycle counting, the entire duration of the CIE ⁄PETM in Zumaia is estimated in �168 ± 16 ka. Moreover, the investigation of palynofacies and low-field magnetic susceptibility reveal significant detrital influx during the interval. Several magnetic susceptibility phases and trends are recognised and are interpreted in terms of sea-level fluctuations before, during and after the PETM. Coupled with results from other sections, our data reveal the presence of an unconformity followed by an eustatic sea-level rise (TST) in the latest Palaeocene.
