(Olson, 1985)

Paranthropus aethiopicus is an extinct species of Paranthropus. The finding discovered in 1985 in West Turkana, Kenya, KNM WT 17000 (known as the "Black Skull" due to the dark coloration of the bone, caused by high levels of magnesium), is one of the earliest examples of robust pliocene hominids. The skull is dated to 2.5 million years old, older than the later forms of robust australopithecines. Anthropologists suggest that P. aethiopicus lived from 2.7 and 2.5 million years ago. The features are quite primitive and share many traits with Australopithecus afarensis, thus P. aethiopicus is likely to be a direct descendant. With its face being as projecting as A. afarensis, its brain size was also quite small at 410 cc.

P. aethiopicus was first found in Ethiopia in 1968 as the first assigned specimen. Lower jaw and teeth fragments have been uncovered. P. aethiopicus had a large sagittal crest and zygomatic arch adapted for heavy chewing (as in gorilla skulls). Not much is known about this species since the best evidence comes from the black skull and the jaw. There is not enough material to make an assessment to how tall they were, but they may have been as tall as Australopithecus afarensis. A Sagittal crest is a ridge of bone running lengthwise along the midline of the top of the skull (at the sagittal suture) of many mammalian and primate skulls, among others. ... The zygomatic bone (also known as the zygoma; Os Zygomaticum; Malar Bone) is a paired bone of the human skull. ... Type Species Troglodytes gorilla Savage, 1847 Species Gorilla gorilla Gorilla beringei The gorilla, the largest of the primates, is a ground-dwelling herbivore that inhabits the forests of Africa. ...


Not all anthropologists agree that P. aethiopicus gave rise to both Paranthropus boisei and Paranthropus robustus, since the skull more closely resembles that of A. afarensis. The one clue that makes P. aethiopicus a possible ancestor to both P. boisei and P. robustus is the similarity in jaw size. P. athiopicus is known to have lived in mixed savanna and woodland. More evidence must be gathered about P. aethiopicus in order to accurately describe its physiology. The "Black Skull"'s bizarre primitive shape gives evidence that P. aethiopicus and the other australopithecines are on an evolutionary branch of the hominid tree, distinctly diverging from the Homo (human) lineage. Binomial name Paranthropus boisei (Mary Leakey, 1959) Paranthropus boisei had a skull highly specialized for heavy chewing. ...

Paranthropus is an extinct genus of bipedal hominid that is probably descended from the Australopithecine hominids (Australopethicus).
Paranthropus is thought to have lived in wooded areas rather than the grasslands of the Australopithecus.
The behavior of Paranthropus was quite different from that of the genus Homo, in that it was not as adaptable to its envirenment or as resourceful.
