This undated picture released by Institute of Human Origins at Arizona State University shows the Burtele foot, which had been a mystery since being discovered in Afar Region in Ethiopia, in 2009, with its elements in the anatomical position. Newly discovered fossils, including a jawbone with 12 teeth, prove that a mysterious foot found in Ethiopia in 2009 belongs to a little-known, recently named ancient human relative who lived alongside the species of the famous Lucy, scientists said on November 26, 2025.
