"We also found that the Paranthropus
cranium was relatively thin and essentially composed of compact bone.
This stands in contrast to Paranthropus
, the lineage of robust hominids whose massive jaw muscles envelop a much smaller cranium, often with a sagittal crest for extra attachment surface.
The human fossil record has two extinctions: Paranthropus
, which disappeared a million years ago, and Neanderthalis, which died out 30,000 years ago.
A major group of early hominids are the australopithecines, known only from the African continent, and including several species subsumed under three to five genera; Australopithecus, Paranthropus
, Ardipithecus, and Kenyanthropus are probably stable.
Quantitative analysis of occlusal microwear in Australopithecus and Paranthropus
. Scanning Microscopy 1:647-656.
Coon divides the races into five categories--Australoid, Mongoloid, Caucasoid, Congoid, and Capoids--and supports his thesis with photographs of African persons in close proximity to photographs of lemurs, chimpanzees, and gorillas (plates 8-16), as well as comparative analyses of skulls and bone fragments of the early hominin Paranthropus
boisei and Australian aborigines (plate 23).

boisei on the prowl; CAVEMAN CALLING: David Rubin rings the changes
boisei son suficientes para colocarlos en un genero aparte, para el cual se ha revivido el nombre del genero Paranthropus
, propuesto originalmente por Broom (Eldredge y Tattersall, 1986).
In a paper published Sunday, scientists think the answer lies with an extinct distant ancestor called Paranthropus
Using CT scans and digital technology, Quam's team reconstructed the ear anatomies of two Australopithecus africanus partial skulls and one Paranthropus
Researchers found a partial skeleton-including arm, hand, leg and foot fragments-dated to 1.34 million years old and belonging to Paranthropus
boisei at the Olduvai Gorge World Heritage fossil site in Tanzania.
naledi has more than twice the chipping rate of (http://humanorigins.si.edu/evidence/human-fossils/species/australopithecus-africanus) Australopithecus africanus , and four times that of (http://humanorigins.si.edu/evidence/human-fossils/species/paranthropus-robustus) Paranthropus
robustus , two extinct hominin species often thought to have commonly consumed hard foods (though there's still a lot of discussion about exactly what their diet consisted of).
But traits such as sturdy jaws and thick tooth enamel recall Paranthropus
, an African hominid line that existed from about 2.5 million to 1 million years ago.
The international team of researchers from institutions in the US, Italy and Spain, analyzed several auditory ossicles representing the early hominin species Paranthropus
robustus and Australopithecus africanus.
