Objective Our aim was to recover new evidence of the evolution of the hominid lineage. Methods We undertook paleontological fieldwork at Olduvai Gorge, Tanzania, in one of the richest paleoanthropological sites in the world, documenting the evolution of our lineage and its environmental contexts over the last 2 million years. Results During field work in 2012, the Olduvai Vertebrate Paleontology Project discovered the distal end of a hominid ulna (OH 82) on the north side of Olduvai Gorge a few meters west of the Third Fault, eroding from Bed III sediments that are ∼1 million years in age. Discussion The size and morphology of this distal ulna falls within the normal range of variation seen in humans, although at the larger end of the distribution.
