jan 1, 195000 BC - Omo Remains
Description:
The Omo remains are a collection of hominin[note 1] bones discovered between 1967 and 1974 at the Omo Kibish sites near the Omo River, in Omo National Park in south-western Ethiopia.[1] The bones were recovered by a scientific team from the Kenya National Museums directed by Richard Leakey and others.[2] The remains from Kamoya's Hominid Site (KHS) were called Omo I and those from Paul I. Abell's Hominid Site (PHS) Omo II.The bones include two partial skulls, four jaws, a legbone, around two hundred teeth and several other parts.[1] The specimens, Omo I and Omo II, are both classified as anatomically modern humans (or Homo sapiens) but differ from each other in morphological traits. The Omo I fossils indicate more modern traits, while Studies of the postcranial remains of Omo II indicate an overall modern human morphology with some primitive features.
About 30 years after the original finds, a detailed stratigraphic analysis of the area surrounding the fossils was done. The Member I layer was argon-dated to 195,000 years ago, and the (higher layer) Member III was dated to 105,000 years ago. Numerous recent lithic records verify the tool technology from Members I and III to the Middle Stone Age.
