Stone Age Graveyard in the Sahara

A paleontologist looking for dinosaur bones in the Sahara desert instead stumbled across the largest Stone Age graveyard ever found. The human skeletons, tools and other remains were left by two groups of people, the Kiffians and the Tenerians, who lived in the area between 5,000 and 10,000 years ago, when the Sahara was a swampy wetland.
