Résumé
Available evidence indicates that climate in North-West Africa has varied strongly since the Last Interglacial between periods of humidity and aridity, along with expansions and contractions in the northern fringe of the Sahara Desert. This research explores past humid and arid climate shifts in North Africa over the last 100ka using stable oxygen and carbon isotopes from small mammal teeth excavated from archaeological cave sites located on the Mediterranean coastal plain of Morocco. Here we present modern and pilot archaeological stable isotope data from Meriones and Gerbillus that demonstrate patterned isotope variability across mesic and arid environments, and temporal shifts indicating moisture changes in the past.
