英文摘要	The Greater Cape Floristic Region of South Africa was critical to the evolution of early modern humans (Homo sapiens) during the Pleistocene. The now submerged continental shelf formed its own ecosystem, the Palaeo-Agulhas Plain (PAP), where early humans lived and foraged. Grazing animals living on the plain might have migrated east and west tracking seasonally varying rains—a hypothesis tested here by examining δ13C and δ18O of serially-drilled teeth from seven ungulate genera: Alcelaphus, Connochaetes, Antidorcus, Redunca, Damaliscus, and Hippotragus. Modern observations and paleoecological reconstructions indicate that summer rainfall areas to the east have more C4 grasses while the winter rainfall areas to the west have more C3 grasses, and that summer and winter rains differ in δ18O. Thus, we analyze δ13C and δ18O preserved in herbivore teeth from the site of PP30 (a hyena den dating to ∼151 ka) to infer diet and water source throughout tooth formation. On a generic level, none of the samples exhibit δ13C or δ18O values that differ significantly from a taxon that likely foraged locally through the year (Southern reedbuck, Redunca arundium). Overall, results indicate that the PAP could support herbivore populations year-round without substantial migration, providing an ecosystem ideal for human inhabitants. © 2020 Elsevier Ltd
