SENEGAL: Flooding in the Dakar suburb of Ouest-Foire has revealed hundreds of shell beads, pieces of pottery, stone and iron tools, and other Neolithic artifacts that could date to 3000 B.C. The items were found by accident while a local archaeologist was examining a construction site damaged by torrential rains. The site is now heavily disturbed and further excavation will be difficult because of the rapid, anarchic pace of building around the capital. —Samir S. Patel
