Study also brings it closer to the age given to oldest Homo sapiens remains, which were discovered in 2017 in Morocco.New minimum age for Omo I is consistent with most recent theories of human evolution.However, availability of more refined methods made the team to link ash layer to an eruption of Shala volcano. Earlier, it was nearly impossible as ash was so fine. A more precise date means, to analyse the thick layers of ash. How was the date calculated?ĭate was calculated by analysing the layers of ash deposited on the fossils. That made the fossil at least that old as well as, oldest ever discovered at the time. They came to conclude that, Omo I was at least 195,000 years old. In 2005, Geologists had analysed the layer of rock just underneath the findings. As a result, experts remained divided over their age for long. It was difficult to date directly because, it contained only bone and skull fragments.Omo Kibish I was first unearthed in Ethiopia in 1967. ![]() The study used volcanic ash to date the fossils and thus there were 22,000-year margin of error.
