The canine teeth are much smaller than those of modern apes, but larger and more pointed than those of humans, and shape of the jaw is between the rectangular shape of apes and the parabolic shape of humans. Species Paranthropus aethiopicus Paranthropus boisei Paranthropus robustus The robust australopithecines, members of the extinct hominin genus Paranthropus, were bipedal hominins that probably descended from the gracile australopithecine hominins (Australopithecus). Over time, the genus has changed from Zinjanthropus to Australopithecus to Paranthropus, but some researchers are still using genus: Australopithecus.. PHYLOGENY. Our virtual cranial capacity estimate for LB1 is 417 cm3 (10). Paranthropus aethiopicus is a species of early hominin that lived in East Africa approximately 2.7–2.3 million years ago (mya). Moreover, the skull has the same general appearance as that of a chimpanzee. It was described by Walker, Leakey, Harris and Brown in Nature in 1986. 1 Description 2 Disputed taxonomy 3 Occurrence 4 Intelligence 5 Discovery 6 See also 7 … aethiopicus, and the thickest dental enamel of any known early human. The cranial capacity of P. robustus is slightly larger than P. aethiopicus, but not substantial. However, it has still been suggested that the cognitive capabilities of the more recent members of Paranthropus were considerably greater than those of P. aethiopicus and the earliest members of the genus Australopithecus (Klein, 1999). Key physical features All three species share similar physical characteristics - a relatively small body and a ‘robust’ or strongly built skull including large lower jaws with extremely large molar teeth. Later, the three robust species (aethiopicus, boisei, ... Paranthropus boisei. KNM WT 17000 had a relatively small cranial capacity, only reaching about 410 cc 1. Support for P. boisei being descended from Au. Besides having a small neurocranium, the face, palate, and cranial base are all very massively built 4. The large sagittal crest preserved on KNM WT 17000 suggests powerful biting forces. The brain size of this erstwhile hominid was only about 350 cc, similar to that of a modern chimpanzee (human mean cranial capacity is 1350 cc). Cranial capacity varied from about 375 to 550 cc. KNM-WT 17000 (Paranthropus aethiopicus), 10 humans, 10 gorillas, 18 chimpanzees (9), an adult female pygmy, and five Homo erectus skulls. The name Paranthropus walkeri is under review and this species is often referred to as Paranthropus (or Australopithecus) aethiopicus. Also known as Australopithecus aethiopicus Sites: Kenya, West side of Lake Turkana, Omo River basin in southern Ethiopia Age: 2.7 - 1.9 mya Type specimen: WT 17000 ("Black skull") Specimens: Omo 18-18, WT 17000, KNM-WT 17000 Cranial capacity: 410 cm3 Cranial architecture: Similar to A. afarensis: Flattened cranial base; Compound temporal nuchal crest Virtual endocasts of the microcephalic, modern woman, Homo erectus, and chimpanzee were scaled to 417 cm3 to Fossils from more than 100 individuals have been recovered in the last 55 years. Its designation as a hominin indicates that it is more closely related to modern humans than to any other living primate. Evolutionary Tree Information: P. boisei is usually thought to descend from earlier P. aethiopicus (who ... Olorgesailie, Kenya. The Australopithecus aethiopicus Skull KNM-WT 17000 was discovered by A. Walker in 1985 on the west shore of Lake Turkana in northern Kenya. “Zinj” - Paranthropus boisei “Zinj” is the name given to a 1.8 million-year-old skull of the Paranthropus boisei species found in 1959 in the Olduvai Gorge of Tanzania. The skull is similar to that of a chimpanzee, except for the more humanlike teeth. aethiopicus has steadily increased. However, some still group P. boisei … Black Skull had a cranial capacity of 410 cc, and the shape of his mouth indicates that he had a strong bite and could chew plants. Australopithecus aethiopicus Cranium KNM-WT 17000 BH-008 $208.00 2.5 MYA.
