Mapping Ancient Africa: Video of seminar 19

On the 25 July 2024 the 19th Mapping Ancient Africa (MAA) seminar, entitled Climate frameworks for the Middle Stone Age and Later Stone Age in Northwest Africa, was delivered by Solène Boisard (University Montreal). In the seminar Solène presented two lines of evidence for past climate change in north-western Africa over the last c. 70,000 years. One from mechanistic climate models (via the PastClim package, for more details see: Leonardi et al. 2023) and one from reconstructions based on archaeological evidence. She found good agreement between the two approaches and linked climatic changes to the transition from Middle Stone Age to Late Stone Age technologies.
