World-atlas stage: Homo sapiens and migrations
Region: Africa · Ethiopia
Languages and scripts: Not named in this record
Important people: No individual is centered in this record
Events and changes: At least c. 233,000 years ago: Omo I was deposited below the KHS volcanic ash, establishing a minimum age rather than an exact burial date; 1967 CE: The Omo I skeletal remains were excavated from the Kibish Formation; 2022 CE: Geochemical correlation of the KHS ash with the Shala eruption produced the revised minimum-age constraint
Evidence confidence: The latest dating provides a minimum age rather than an exact birth date for the population.

Historical geography

A dated anchor, not an exact border

The local map uses modern coastlines only for orientation. The marker identifies this record's geographic anchor, not the full reach of a community or polity.

Map geometry loads only when requested. Modern outlines are orientation only; historical geography and identities changed through time.
