Originally from South Africa, Paranthropus Robustus was bipedal and walked straight upright, on its two feet. They had a very thick jaw with small incisors and canines, large molar-like premolars and very large molars. Such a small number of specimens of Paranthropus aethiopicus have been found that little is really known about this hominid beyond the structure and appearance of the cranium.

Here we present evidence of hominin locomotor behavior from the trabecular bone of the femur. Homo erectus 7. Anatomy: Brain size around 530cc, weight 50-70kg, height 1.1-1.3m. Paranthropus robustus is the last of the Paranthropus Group of human ancestors. It has been suggested that bipedalism was selected for because it made it easier to see long distances when moving over areas covered with tall grasses.
Paranthropus boisei 5. africanus, which include an inferiorly oriented foramen magnum, modern human-like talus, relatively long femoral neck, and a bicondylar angle.

Homo sapiens. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Homo neanderthalensis 8. The Genus Paranthropus P. boisei P. aethiopicus P. robustus. Bipedal locomotion may have been an adaptation to living in a mixed woodland and grassland environment.

They lived in open savannah. Robinson.This juvenile calotte (skull cap) possesses two 6mm puncture wounds close to the intersection of the sagittal and lambdoidal sutures (Brain 1981). The oldest Paranthropus boisei was found at Omo, Ethiopia and dates to approximately 2.3 million years ago, while the youngest was found at Olduvai Gorge, and dates to approximately 1.2 million years ago. 1.5-2 MYA. In addition, aspects of the elbow, knee, and tibia were more derived, indicating its bipedal mode of locomotion. Like other members of the Paranthropus genus, P. boisei is characterized by a specialized skull with adaptations for heavy chewing.A strong sagittal crest on the midline of the top of the skull anchored the temporalis muscles (large chewing muscles) from the top and side of the braincase to the lower jaw, and thus moved the massive jaw up and down.
This species lived between 1.8 million and 1.2 million years ago in South Africa. Laetoli footprint trail. So I have extended my search into the post- cranial specimens of all P. boisei species. A robustus SK-54 Cranium Section with Punctures BHK-001 $165.00 . This week, we saw a short paper in Science on Paranthropus robustus sexual dimorphism and the implications the differences between sexes had on this early hominid social behavior. It has been suggested that bipedalism was selected for because it made it easier to see long distances when moving over areas covered with tall grasses. Also known as Paranthropus robustus. Paranthropus robustus 6. StW 311, a proximal femur dated to 1.1-2.18 Ma and may be attributed to either Paranthropus robustus or a species of early Homo (e.g., Homo habilis).
