Paranthropus boisei is a species of australopithecine from the Early Pleistocene of East Africa about 2.5 to 1.15 million years ago. [1] The holotype specimen , OH 5 , was discovered by palaeoanthropologist Mary Leakey in 1959 at Olduvai Gorge, Tanzania and described by her husband Louis a month later.

A P. aethiopicus ulna, on the other hand, shows more similarities to Homo than P. boisei. [46] Paranthropus were bipeds, and their hips, legs and feet resemble A. afarensis and modern humans. [48] [49] The pelvis is similar to A. afarensis, but the hip joints are smaller in P. robustus. The physical similarity implies a similar walking gait. [50]
Homo erectus, a direct ancestor of humans, lasted for a million more years, while Paranthropus boisei went extinct within the next few hundred thousand years. The reason why remains a mystery, and ...
Oldowan tools occur in Beds I–IV at Olduvai Gorge. Bed I, dated 1.85 to 1.7 mya, contains Oldowan tools and fossils of Paranthropus boisei and Homo habilis, as does Bed II, 1.7 to 1.2 mya. H. habilis gave way to Homo erectus at about 1.6 mya, but P. boisei persisted. Oldowan tools continue to Bed IV at 800,000 to 600,000 before present . A ...

Paranthropus boisei, the last species included in the genus Paranthropus, was first found in Olduvai Gorge, Tanzania and around Ethiopia and Kenya. [10] P. boisei was known for massive facial and dental bones and structure, primarily larger mandibles, molars, and premolars, which was an adaptation allowing them to consume hard plant foods with ...
Paranthropus boisei was a hominid species dated to have lived from 2.3 to 1.2 million years ago. The evidence from fossils shows morphological traits designed for chewing hard, tough foods and is commonly referred to as the ‘nutcracker man’. [11]
