- •
Paleoclimate predictions suggest Marine Isotope Stage (MIS) 13 is characterized by an intense African monsoonal episode.
- •
Carbon isotopic ratios (δ13C) from bovid tooth enamel and pedogenic carbonates determine paleovegetation during MIS 13 for the Kapthurin Formation, Kenya.
- •
Oxygen isotopic ratios (δ18O) from bovid tooth enamel and pedogenic carbonates determine aridity during MIS 13 for the Kapthurin Formation, Kenya.
- •
Riparian woodlands, wooded grasslands, and grassland ecosystems are reconstructed, with mesic conditions.
- •
The presence of an intense African monsoonal episode is likely during MIS 13.
