[1][2] The fossil's characteristics include a robust build with a prominent sagittal crest.

Its distinct coloration is due to the high manganese content of the material it was embedded in.

[2] This fossilized cranium's face projects far outward from the forehead, has wide flared zygomatic arches, and has a large sagittal crest.

The molar and premolar roots in the jaw are indicative of this early human having massive cheek teeth; an adaptation for heavy chewing.

[1][2][3] While its relationship to other fossil hominin taxa was not immediately clear at the time of its discovery, further studies have suggested it is a possible ancestor of two species: Paranthropus boisei, of east Africa, and Paranthropus robustus, of South Africa.
