Which species is the common ancestor of Paranthropus robustus and Paranthropus boisei?

P. boisei is usually thought to descend from earlier P. aethiopicus (who inhabited the same geographic area just a few hundred thousand years before) and lived alongside several other species of early humans during its 1.1 million year existence.

How many species of robust Australopithecus have been identified?

three
Ever since Broom’s 1949 announcement of a new type of hominin from Swartkrans, paleoanthropologists have been debating the taxonomy and phylogeny of the “robust” australopiths 9,10,22,42-47 (Fig. 3). Placing the three commonly recognized species (P. robustus, P.

Where was Australopithecus boisei found?

… hominin (of human lineage) species Paranthropus boisei containing a complete set of adult teeth. It was found in 1964 at Peninj, a locale in Tanzania to the west of Lake Natron and about 80 km (50 miles) from Olduvai Gorge, a major paleoanthropological site.

Where was boisei found?

Fossils of both Paranthropus walkeri and the more recent species Paranthropus boisei have been found in the countries of Ethiopia, Kenya and Tanzania in east Africa. Fossils of Paranthropus robustus have been excavated from South Africa, including over 100 specimens from the limestone cave of Swartkrans.

In 1959, another and much more robust australopithecine was discovered in East Africa, P. boisei, and in 1975, the P. boisei skull KNM-ER 406 was demonstrated to have been contemporaneous with the H. ergaster/H. erectus skull KNM ER 3733 (which is considered a human ancestor).

Approximate time ranges of sites yielding australopith fossils. …lineage) that her husband named Zinjanthropus, or “eastern man,” though it is now regarded as Paranthropus, a type of australopith, or “southern ape.”

How old are the remains of Australopithecus robustus?

As with the remains of A. africanus, the only method of dating the P. robustus remains is via biostratigraphy, which indicates that P. robustus dates from about 1.8–1.5 mya. Specimens attributed to Homo also occur in the same deposits, but these are much rarer.

Where was the Australopithecus boisei found in Tanzania?

It was found in 1964 at Peninj, a locale in Tanzania to the west of Lake Natron and about 80 km (50 miles) from Olduvai Gorge, a major paleoanthropological site. Australopithecus robustus and A. boisei are also referred to as “robust” australopiths.
