Life-size reproduction in bioplastic and resin of an Australopithecus (Paranthropus boisei) skull, female KNM-ER 732
Discovered by Richard Leakey and H. Mutua in 1970 at the Koobi Fora site, Kenya Age 1.7 MA
This partial skull of a female Paranthropus boisei has many characteristics of P. boisei.
Most notable is the root placed toward the front of the zygomatic arch, resulting in a broad, flat face.
This skull has a cranial capacity of 500 cc, almost identical to the 510 cc of putative male P. boisei KNM-ER 406.
the face is overall less massive and it does not have a sagittal crest.
From this, scientists conclude that KNM-ER 732 represents a female of the species Paranthropus boisei.
This fossil provides clues to the nature of sexual dimorphism in this early human species.
