Photographer Mike Hettwer has been kind enough to share with us some of his photographs depicting what remains of the Green Sahara. About 9,000 years ago, a very wet climate prevailed in parts of the Sahara Desert called the Neolithic Subpluvial period. Lasting several thousand years, this Green Sahara was home to many grassland and woodland animals as well as humans. While on an expedition for dinosaur fossils with paleontologist Paul Sereno in Niger in 2000, Hettwer discovered a burial area containing hundreds of skeletons from two distinct cultures, each thousands of years old - the Kiffian and Tenerian. Also found in the dry and desolate site were hunting tools, pottery, and bones of large land animals and fish. Mike Hettwer's photographs have appeared in 2,500 magazines, newspapers books and web sites - many of these photos are from his article "Lost Tribes of the Green Sahara" in the Sep. 2008 issue of National Geographic.
