Why did Paranthropus have large molars?
Why did Paranthropus have large molars?
Robust species like Paranthropus robustus had large teeth as well as a ridge on top of the skull, where strong chewing muscles attached. These features allowed individuals to crush and grind hard foods such as nuts, seeds, roots, and tubers in the back of the jaw; however, P. robustus didn’t just eat tough foods.
What are some distinctive traits of Paranthropus?
Paranthropus is characterised by robust skulls, with a prominent gorilla-like sagittal crest along the midline—which suggest strong chewing muscles—and broad, herbivorous teeth used for grinding. However, they likely preferred soft food over tough and hard food. Paranthropus species were generalist feeders, but P.
Was Paranthropus robustus a human?
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.
Where were Paranthropus robustus 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.
Why did Paranthropus robustus go extinct?
Whereas the ancestors of humans were thought to be adaptable generalists, Paranthropus species, which evolved massive teeth and jaws for chewing hard vegetation, were thought to have hit an evolutionary dead end because they were too specialised to adapt to new food sources produced by Africa’s changing climate.
What do Paranthropus eat?
tiger-nuts
Paranthropus boisei, an early hominin that lived in East Africa between 2.3 and 1.2 million years ago, mainly ate tiger-nuts – edible bulbous tubers of the sedge Cyperus esculentus (also known as nut grass, chufa sedge, yellow nutsedge or earth almond), according to a new study involving modern-day baboons.
Where is Paranthropus robustus found?
What did the robust australopithecines Paranthropus robustus and Paranthropus boisei eat?
The East African hominin Paranthropus boisei possessed large and low-cusped postcanine dentition, large and thick mandibular corpora, and powerful muscles of mastication, which are generally believed to be adaptations for a diet of nuts, seeds, and hard fruit (1–3).
What dietary adaptations did Paranthropus have?
What is the meaning of robustus?

What happened to the robust australopithecines?
The “robust” australopiths are a group of hominins with large cheek teeth and strongly built jaws that lived alongside the earliest members of our own genus, Homo, approximately 2.5-1.4 million years ago. Why they ultimately went extinct while we set off to conquer the world is still a mystery.
What are the characteristics of Paranthropus robustus?
Paranthropus robustus is an example of a robust australopithecine; they had very large megadont cheek teeth with thick enamel and focused their chewing in the back of the jaw. Large zygomatic arches (cheek bones) allowed the passage of large chewing muscles to the jaw and gave P. robustus individuals their characteristically wide, dish-shaped face.
What is another name for Paranthropus?
Various other names have been used over the years. Paranthropus boisei was initially known as Zinjanthropus boisei and some P. robustus specimens were originally named Paranthropus crassidens. The name Paranthropus walkeri is under review and this species is often referred to as Paranthropus (or Australopithecus) aethiopicus.
How old is the Paranthropus boisei skull?
A cast of a Paranthropus boisei skull OH 5. The skull was discovered in1959 by Mary Leakey in Olduvai Gorge, Tanzania and dates to about 1.8 million years old. This is the ‘type specimen’ or official representative of this species.
What are the patterns of resource use in Homo and Paranthropus?
Patterns of resource use in early Homo and Paranthropus. Journal of Human Evolution 46, 119–162. This Paranthropus robustus skull is likely from a female, because it is smaller in size and has a smaller crest than males of this species . SK 46 preserves the left half of the braincase and the nearly complete palate of Paranthropus robustus.
