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.
