Amazingly, isotopic analyses of strontium in their teeth indicates that females did not grow up where their fossils are found (Copeland et al. In modern day, D. mombuttense only grows in the Congolian rainforests, so its presence could potentially mean the area was an extension of this rainforest.

Stone tools are conspicuously absent from levels at Sterkfontein associated with A. africanus (Members 2 and 4), but, during the time of Member 5, tools are abundant. [44] In 2012, American anthropologist Trenton Holliday, using the same equation as McHenry on 3 specimens, reported an average of 37 kg (82 lb) with a range of 30–43 kg (66–95 lb). Based on colour and structural changes, they found that 46 were heated to below 300 °C (572 °F), 52 to 300–400 °C (572–752 °F), 45 to 400–500 °C (752–932 °F), and 127 above this.
Studies examining carbon isotope ratios found in tooth enamel suggests A. boisei was a grass eater. This may indicate a walking gait more similar to early hominins than to modern humans (less efficient gait). Based on this, he concluded babies were birthed at intervals of 3 to 4 years using a statistical test to maximise children born. The carnivore assemblage comprises the sabertoothed cats Dinofelis and Megantereon, and the hyena Lycyaenops silberbergi. Instead, P. robustus and P. boisei evolved many robust features independently, and they were proposed to have both evolved from P. aethiopicus assuming Paranthropus is valid. Such a mix may reflect habitual locomotion both in the trees and walking while upright because inner ear anatomy affects the vestibular system (sense of balance).

The extinction of P. robustus coincides with the Mid-Pleistocene Transition, and the doubling of glacial cycle duration. Did Megafauna die from hunting or climate change? [57] The femoral head StW 311, which either belongs to P. robustus or early Homo, seems to have habitually been placed in highly flexed positions, which would be consistent with frequent climbing activity. These could have bearing on the amount of time spent upright compared to other australopithecines. However, it is argued that Paranthropus is an invalid grouping and synonymous with Australopithecus, so the species is also often classified as Australopithecus robustus. robustus. In total, the Cradle of Humankind may have featured gallery forests surrounded by grasslands. (2016) indicate that it may be a form of Homo erectus.

The intermediate phalanges are stout and straight like humans, but have stouter bases and better developed flexor impressions. This contrasts with other primates which flash the typically engorged canines in agonistic display (the canines of Paranthropus are comparatively small). Though A. africanus had an adducted big toe (it was not dextrous) like humans, A. africanus likely did not push off with the big toe, using the side of the foot instead. [20], Drimolen Cave was first discovered to have yielded hominin remains by Keyser in 1992, who, in 8 years, oversaw the recovery of 79 P. robustus specimens.

It is unclear if frequent squatting could be a valid alternative interpretation.

[7] However, in 1953, South African palaeontologist John Talbot Robinson believed that splitting species and genera on such fine hairs was unjustified, and that australopithecine remains from East Africa recovered over the previous couple of decades were indistinguishable from "Plesianthropus"/A. [14] Many hominin specimens traditionally assigned to A. africanus have been recovered from Sterkfontein Member 4 (including Mrs. Ples and 2 partial skeletons) dating from 2.8–2.15 million years ago, and it is the most productive Australopithecus-bearing deposit.

Paranthropus robustus (or Australopithecus robustus) was originally discovered at Kromdraai in South Africa in 1938 by the anthropologist Robert Broom.
