Omo remains
The Omo remains are a collection of
Fossils
The bones found include two partial skulls, four jaws, a legbone, approximately two hundred teeth, and several other fossilized parts.
Because of the very limited fauna and the few stone artifacts that were found at the sites when the original Omo remains were discovered, the provenance and estimated age of the Kibish hominids are uncertain.[2] In 2008, new bone remains were discovered from Awoke's Hominid Site (AHS). The AHS fossil's tibia and fibula were unearthed from Member I, the same layer from which the other Omo remains derive.[6]
Dating and implications
About 30 years after the original finds, a detailed stratigraphic analysis of the area surrounding the fossils was conducted. The Member I layer was
The lower layer, Member I, (below the fossils) is considerably older than the 160,000-year-old
Parts of the fossils are the earliest to have been classified by Leakey as
In 2022, a study by Vidal et al. found an earlier age for the Omo fossils than previously reported, revising the date assigned to them as, a minimum date of approximately 233,000 years old.[10]

Notes
- ^ hominin", which comprises all members of the human clade after the split from the chimpanzees (Pan). The modern meaning of the term "hominid" refers to all the great apes, including humans. Usage still varies, however, and some scientists and laypersons still use the term in the original restrictive sense; the scholarly literature generally will show the traditional usage until around the end of the 20th century. For further information, see Hominini (at "hominins") and Hominidae(at discussion of the terms "hominid" and "hominin" in the lede section).
In this article, hominid is italicized when the traditional term is necessary to keep as-is—as in a quotation, or a record, or a title, etc.
