The anthropologist Donald Johanson, a member of the 1973 expedition to Hadar, returned the next year and discovered the fossil hominin "Lucy" in the late fall of 1974. [6] He spotted a right proximal ulna in a gully, followed by an occipital bone, a femur, some ribs, a pelvis, and a lower jaw.
The team returned for the second field season in the following year and found hominid jaws. Then, on the morning of November 24, 1974, Johanson and Gray were searching in a gully about two and a half kilometres from the site where the knee joint had been discovered, where Johanson found the first fossil fragment of Lucy (Australopithecus).
