Recent excavations in Level 4 at BK (Bed II, Olduvai Gorge, Tanzania) have yielded nine hominin teeth, a distal humerus fragment, a proximal radius with much of its shaft, a femur shaft, and a tibia shaft fragment (cataloged collectively as OH 80). Those elements identified more specifically than to simply Hominidae gen. et sp. indet are attributed to Paranthropus boisei. Before this study, incontrovertible P. boisei partial skeletons, for which postcranial remains occurred in association with taxonomically diagnostic craniodental remains, were unknown. Thus, OH 80 stands as the first unambiguous, dentally associated Paranthropus partial skeleton from East Africa. The morphology and size of its constituent parts suggest that the fossils derived from an extremely robust individual who, at 1.338±0.024 Ma (1 sigma), represents one of the most recent occurrences of Paranthropus before its extinction in East Africa.
近期在坦桑尼亚奥杜威峡谷BK遗址第4层的发掘工作出土了9颗人科动物牙齿、一块肱骨远端碎片、一段带有大部分骨干的桡骨近端、一根股骨干以及一块胫骨骨干碎片（这些标本统称为OH 80）。那些比简单的人科未定属种更明确鉴定出的标本被归为鲍氏傍人。在本研究之前，尚无无可争议的鲍氏傍人部分骨骼，其颅后遗骸与分类学诊断性的颅齿遗骸同时出现。因此，OH 80是东非首个明确无误的、与牙齿相关的傍人部分骨骼。其组成部分的形态和大小表明，这些化石来自一个极其粗壮的个体，该个体生活在距今133.8±2.4万年（1个标准差），是东非傍人灭绝之前最近期的出现个体之一。
