Omo Kibish Formation
The Omo Kibish Formation or simply Kibish Formation is a rock formation in southern Ethiopia. It is named after the archaeological site of Omo Kibish on the Omo River, where it was first studied. Omo-Kibish I from southern Ethiopia is one of the oldest anatomically modern Homo sapiens skeleton currently known.
Omo Kibish Formation and its neighboring sites have produced some of the earliest examples of fossilized human and australopithecine remains and stone tools. Richard Leakey's work there in 1967 found some of the oldest remains of anatomically modern Homo sapiens. Earlier believed to be around 125,000 years old, more recent research indicates they may date to c.195,000 years ago.
