jethro cave dating - The challenge of direct dating old human fossils

It’s a place that is well known for hominin fossils – that is, bones from early humans – first excavated in the 1960s.
fossils (Omo Kibish, estimated age 195,000 years, and Herto, estimated age 160,000 years), both found in modern-day Ethiopia, East Africa.
But new research, published today in two Nature papers, offers a fresh perspective.
