Paranthropus boisei (KNM-ER 732) Female Cast Replica Skull #BH-026

-Size: 6½"L x 5½"W x 4"H

-Species: Paranthropus boisei

-Notes: This 1.7 million year old Paranthropus boisei Skull (KNM-ER 732) was discovered in 1970 at Koobi Fora, Kenya by R. Leakey and H. Mutua and described in Nature in 1971. A comparative analysis of KNM ER 732 and KNM ER 406 revealed a host of similarities with the only differences (e.g., smaller size, lack of sagittal and nuchal crests in KNM-ER 732) being typical of the sexual dimorphism found in great ape skulls. Consequently, KNM-ER 732 is considered to be a female and KNM-ER 406 a male of the species, Paranthropus boisei. Using the sexual dimorphism found in this pair as a guide, researchers suggested that P. robustus and A. africanus, which had been hypothesized by some to be male and female specimens of the same species, were, in fact, far more different than one would expect from simple sexual dimorphism. They proposed instead that P. robustus and A. africanus were separate species.
