title: Proximal femur articulation in Pliocene hominids.
abstract: The supposed "nonhuman anthropoid"-type femur head articular surface described for the Pliocene hominid specimen A.L.288-1 ("Lucy") by Stern and Susman in 1983 is present in significant numbers of modern human femora. This nonmetric skeletal trait was also found to be sex-related in modern human samples examined.
