Quick Summary

The Kaguerian-Kamasian Interpluvial was a geologic period in Africa, occurring approximately 500,000 years ago. This period was characterized by drier conditions, occurring between times of greater precipitation, as indicated by the term "interpluvial". During this time, remains of Homo erectus have been found at Olduvai Gorge in Tanzania, as well as in Morocco, Algeria, and Chad. This interpluvial period followed the Kaguerian Series, which dates back three to four million years and contains fossils of the genus Australopithecus. The Kaguerian-Kamasian Interpluvial represents a phase of alternating humid and arid conditions in Africa during the Pleistocene Epoch.12
