Sibudu Cave excavations have yielded an Iron Age occupation directly overlying a long sequence of final Middle Stone Age (MSA)layers dating c. 61 000–26 000 years ago. Older, undated layers contain a Howiesons Poort Industry. A diverse animal population is represented in the final MSA. Proxy environmental data suggest cooler, drier conditions with a larger savanna component to the vegetation than at present.
