P. robustus was first described by Martius in 1829 as Loranthus robustus, and in 1830, he assigned it to a new genus Psittacanthus. [1] [8] Distribution [ edit ]
INTRODUCTION. In 1938, Robert Broom discovered the first Paranthropus robustus material at the site of Swartkrans, South Africa. He later found material at Kromdraai, and because the molar teeth were more primitive at that site, he changed the species name at Swartkrans to P. crassidens but used P. robustus for the Kromdraai material. Before P. boisei was described (and P. robustus was the only member of Paranthropus), Broom and Robinson continued arguing that P. robustus and A. africanus (the then only known australopithecines) were two distinct lineages. However, remains were not firmly dated, and it was debated if there were indeed multiple hominin lineages or if there Feb 01, 2004 · P. robustus is known only from southern Africa and thus does not overlap geographically with the East African P. boisei and P. aethiopicus.

Paranthropus is a genus of extinct hominin which contains two widely accepted species: P. robustus and P. boisei. However, the validity of Paranthropus is contested, and it is sometimes considered to be synonymous with Australopithecus. They are also referred to as the robust australopithecines. Probustus is all about the automation of processes, industry and technical installations. The challenge is finding the simplest solution.
Paranthropus robustus (considered for a time by the scientific community as Australopithecus robustus) is generally dated to have lived between 2.0 and 1.2 million years ago. P. robustus had large sagittal crests, jaws, jaw muscles, and post-canine teeth that were adapted to serve in the dry environment that they lived in.
This transition only took twenty or thirty thousand years (nothing on an evolutionary timescale). Nov 10, 2020 · DNH 155 is an adult male P. robustus cranium, and thus provides a useful sex based comparison to the female DNH 7 cranium.
Paranthropus robustus belongs to a group that represents a side branch of the human family tree. The paranthropines are a group of three species that range in time from c. 2.6 mya up to c. 1.2 mya. Paranthropus robustus (or Australopithecus robustus) is an early hominin, initially discovered in Southern Africa in 1938. Particularly regarding cranial features, the development of P. robustus

Dental studies suggest the average Paranthropus robustus rarely lived past 17 years of age. Broom's work on the australopithecines showed that the evolution trail leading to Homo sapiens was not just a straight line in the evolutinary tree, but was one of rich diversity.
Who were they? How are we related? Did they give Mar 29, 2019 · Remains of P. robustus have been found in abundance in several South African caves, all situated within the “cradle of humankind” about 50km northwest of Johannesburg. The majority of Feb 06, 2019 · Paranthropus robustus is the last of the Paranthropus Group of human ancestors.
Paranthropus robustus is generally dated to have lived between 2.0 and 1.2 million years ago. P. robustus had large sagittal crests, jaws, jaw muscles, and post-canine teeth that were adapted to serve in the dry environment that they lived in. The fossils include parts of a skull and teeth; all dated to 2 million years old. Paranthropus robustus (considered for a time by the scientific community as Australopithecus robustus) is generally dated to have lived between 2.0 and 1.2 million years ago. P. robustus had large sagittal crests, jaws, jaw muscles, and post-canine teeth that were adapted to serve in the dry environment that they lived in. Kromdraai, and Drimolen) of P. robustus are associated with open and even arid habitats, but these may not reflect its actual foraging preference. Paranthropus is a genus of extinct hominin which contains two widely accepted species: P. robustus and P. boisei.
For instance, the distal phalanx has a pronounced bony connection point for the flexor pollicis longus muscle that originates from the middle part of the anterior radius. 2 million years ago an upright walking group of hominins roamed Africa. Not our ancestors but Paranthropus. Who were they?

Occurrence This new example increases the total number of carious lesions described in P. robustus teeth to 10, on occlusal, interproximal, and now, root surfaces. Beyond the consumption of caries-causing food, caries formation would have also required the presence of requisite intraoral cariogenic bacteria in … Males of the extinct human species Paranthropus robustus were thought to be substantially larger than females — much like the size differences seen in modern-day primates such as gorillas, orangutans and baboons. But a new fossil discovery in South Africa instead suggests that P. robustus evolved rapidly during a turbulent period of local climate change […] Paranthropus robustus is a species of robust australopithecine from the Early and possibly Middle Pleistocene of the Cradle of Humankind, South Africa, about 2 to 1 or 0.6 million years ago. It has been identified in Kromdraai, Swartkrans, Sterkfontein, Gondolin, Cooper's, and Drimolen Caves.
