Quick Summary

Paranthropus boisei skull
Paranthropus boisei skull Reconstructed replica of “Nutcracker Man,” a 1.75-million-year-old Paranthropus boisei skull found in 1959 by archaeologist Mary Leakey at Olduvai Gorge, Tanzania. The skull was originally classified as Zinjanthropus boisei by Louis Leakey.

"Nutcracker Man" refers to the fossil skull specimen OH 5, which is classified as Paranthropus boisei. This extinct primate genus, Paranthropus, lived in eastern and southern Africa between 2.9 and 1.2 million years ago.12

Paranthropus skulls are characterized by a flat face, prominent brow lines, a low-crowned head with a sagittal crest, and large molars, suggesting a vegetarian diet. The name "Nutcracker Man" was given to OH 5 due to its large molars. The discovery of OH 5 by Mary Leakey in 1959 provided strong evidence that hominins evolved in Africa. While some scientists consider Paranthropus a distinct genus, others group its species, including P. aethiopicus, P. robustus, and P. boisei, under Australopithecus.21
