Paranthropus boisei is a species of australopithecine from the Early Pleistocene of East Africa about 2.5 to 1.15 million years ago. [1] The holotype specimen, OH 5, was discovered by palaeoanthropologist Mary Leakey in 1959 at Olduvai Gorge, Tanzania and described by her husband Louis a month later.
Paranthropus boisei was a hominid species dated to have lived from 2.3 to 1.2 million years ago. The evidence from fossils shows morphological traits designed for chewing hard, tough foods and is commonly referred to as the ‘nutcracker man’. [11]
In P. boisei, thick enamel was more likely used to resist abrasive gritty particles rather than to minimize chipping while eating hard foods. [57] In fact, there is a distinct lack of tooth fractures which would have resulted from such activity. [58] [59] Paranthropus were
The team concluded that hominins belonging to the species Homo erectus and the smaller-brained Paranthropus boisei made the footprints. P. bosei made the long trackway, while Homo erectus made the ...
Homo erectus, a direct ancestor of humans, lasted for a million more years, while Paranthropus boisei went extinct within the next few hundred thousand years. The reason why remains a mystery, and ...
Paranthropus boisei, the last species included in the genus Paranthropus, was first found in Olduvai Gorge, Tanzania and around Ethiopia and Kenya. [10] P. boisei was known for massive facial and dental bones and structure, primarily larger mandibles, molars, and premolars, which was an adaptation allowing them to consume hard plant foods with ...
KNM ER 406 is an almost complete fossilized skull of the species Paranthropus boisei. [1] It was discovered in Koobi Fora, Kenya by Richard Leakey and H. Mutua in 1969. [2] This species is grouped with the Australopitecine genus, Paranthropus boisei because of the robusticity of the skull and the prominent characteristics.
Members of Australopithecus are sometimes referred to as the "gracile australopithecines", while Paranthropus are called the "robust australopithecines". [ 11 ] [ 12 ] The australopithecines occurred in the Late Miocene sub-epoch and were bipedal , and they were dentally similar to humans, but with a brain size not much larger than that of ...
