After the ulna was found, the lose dirt around the bone, piled from about 30 square meters of an area, was sieved in order to recover all the bones that might have scattered around after exposure to the surface.

The Woranso-Mille project has been conducting field research in the central Afar region of Ethiopia since 2004. The male Australopithecus afarensis partial skeleton (KSD-VP-1/1), nicknamed "Kadanuumuu," was found at a locality known as Korsi Dora in Ethiopia’s Afar region. This is located about 210 air miles (336 kilometers) northeast of the capital Addis Ababa and 30 air miles (48 kilometers) north of Hadar, the site where the famous "Lucy" skeleton was found in 1974.
