Paranthropus boisei skull

A cast of a Paranthropus boisei skull OH 5. The skull was discovered in1959 by Mary Leakey in Olduvai Gorge, Tanzania and dates to about 1.8 million years old. This is the ‘type specimen’ or official representative of this species. It was originally classified as Zinjanthropus boisei and earned the nickname ‘Nutcracker Man’ because of its powerful jaws and large teeth. No lower jaw was found with this specimen.
