Dating the Dawn of Humanity Omo I skeletal parts (National Museum of Ethiopia) The bones of an early member of our species, Homo sapiens, known as Omo I, excavated from Ethiopia's Kibish rock formation. The bones are kept in the National Museum of Ethiopia. When the first bones from Omo I were found in 1967, they were thought to be 130,000 years old. Later, 160,000-year-old bones of our species were found elsewhere. Now, scientists from the University of Utah, Australian National University and Stony Brook University have determined that Omo I lived about 195,000 years ago -- the oldest known bones of the human species.

Full size image available here Both Omo I and Omo II were buried in the lowermost portion or "member" of the Kibish Formation, a series of annual flood sediments laid down rapidly by the ancient Omo River on the delta where it once entered Lake Turkana. Lake levels now are much lower, and the river enters the lake about 60 miles (100 kilometers) south of Kibish.
