Gobero site in Niger holds over 200 human burials from 9,500 to 4,900 years ago. Oldest Kiffian burials feature tightly crouched skeletons of fisher-foragers. Tenerean burials show side-lying poses with artifacts like arrowheads and beads. Triple burial of woman and two children clutching hands dates to 3400 B.C. with added arrowheads and flowers. Skeletons show perfect health, no trauma, no starvation stress in teeth. Zero evidence of interpersonal violence beyond one healed fracture. People stayed year-round at lake, proven by fish ear bones and strontium isotopes. Almost no cattle bones despite Tenerean herding label. Artifacts include harpoons, fishhooks, ostrich beads, hippo ivory. Fauna proves Green Sahara with hippos, giraffes, catfish, crocodiles. Burials protected by rhizoconcretions from desert erosion. Kiffian culture ended around 8,000 years ago, site flooded then. Tenereans arrived 1,000 years later, possibly non-nomadic. DNA extraction attempted but bones too degraded by heat. Sedentary lifestyle adapted perfectly to lake resources.
