Paranthropus boisei is a species of australopithecine from the Early Pleistocene of East Africa about 2.3 to 1.34 or 1 million years ago. [35] In this model, P. boisei may have been a generalist feeder with a predilection for USOs,[37][34] and may have gone extinct due to an aridity trend and a resultant decline in USOs in tandem with increasing competition with baboons and Homo. [14], Such arguments are based on how one draws the hominin family tree, and the exact classification of Australopithecus species with each other is quite contentious. La scoperta avvenne il 17 luglio 1959 nella gola di Olduvai in Tanzania, ad opera dell'antropologa Mary Leakey. In 1979, a year after describing A. afarensis from East Africa, anthropologists Donald Johanson and Tim D. White suggested that A. afarensis was instead the last common ancestor between Homo and Paranthropus, and A. africanus was the earliest member of the Paranthropus lineage or at least was ancestral to P. robustus, because A. africanus inhabited South Africa before P. robustus, and A. afarensis was at the time the oldest known hominin species at roughly 3.5 million years old. [48] The leg OH 35, which either belongs to P. boisei or H. habilis, shows evidence of leopard predation. Il fossile era costituito da numerosi frammenti del teschio, compresa la mandibola. Jul 7, 2014 - Paranthropus boisei (aka Australopithecus boisei/Zinjantrhopus boisei -- 'robust australopithecine'), Eastern Africa, 2.3 to 1.2 million years ago. L'Australopithecus boisei, attualmente classificato come Paranthropus boisei, è una specie di ominide del genere Australopithecus, vissuto tra 2,6 e 1,2 milioni di anni fa nell'Africa orientale, durante il Pliocene e il Pleistocene. [45] Australopithecines and early Homo likely preferred cooler conditions than later Homo, as there are no australopithecine sites that were below 1,000 m (3,300 ft) in elevation at the time of deposition. They are also referred to as the robust australopithecines. Quick Paranthropus Facts: - Lived from the Pliocene Period through the Pleistocene Period - Lived in what is now Africa - 3 different species made up this genus - First species discovered in 1938 - Tallest species of this genus was over 4 feet tall - Weighed less than a kangaroo It was described as a new genus and species by Robert Broom of the TransvaalMuseum. afarensis. [16] The youngest record of P. boisei comes Olduvai Gorge (OH 80) about 1.34 mya;[10] however, due a large gap in the hominin fossil record, P. boisei may have persisted until 1 mya. Paranthropus boisei este o specie de australopithecina din Pleistocenul timpuriu din Africa de Est care a trăit acum aproximativ 2,3-1,34 sau 1 milion de ani în urmă. Proponents of monophyly consider P. aethiopicus to be ancestral to the other two species, or closely related to the ancestor. [1] Synonymising Paranthropus with Australopithecus was first suggested by anthropologists Sherwood Washburn and Bruce D. Patterson in 1951, who recommended limiting hominin genera to only Australopithecus and Homo. Where Lived:Eastern Africa (Ethiopia, Kenya, Tanzania, Malawi) When Lived:About 2.3 to 1.2 million years ago. Le differenza tra le dimensioni dei due sessi è tipica del dimorfismo sessuale che caratterizza quasi tutte le specie di australopitechi. Learn Paranthropus boisei DISC with free interactive flashcards. Mary e il marito Louis Leakey classificarono la scoperta come Zinjanthropus boisei, dove Zinj derivava da Zanj, il nome dato dagli Arabi ai neri dell'Africa orientale che riducevano in epoca medievale in schiavitù, anthropus che in greco significa uomo e boisei da Charles Boise, che aveva sovvenzionato il team di ricerca. Il primo fossile di Australopithecus boisei, inizialmente classificato come Paranthropus boisei e chiamato Zinjanthropus boisei, venne identificato da Mary Leakey nel 1959 nella gola di … [2] Fu soprannominato "Uomo schiaccianoci" proprio perché i suoi denti sono i più grandi e il suo smalto il più spesso tra tutti gli ominidi finora ritrovati. Palaeoanthropologist Louis Leakey (Mary's husband) believed the skull had a mix of traits from both genera, briefly listing 20 differences, and so used OH 5 as the basis for the new genus and species "Zinjanthropus boisei" on August 15, 1959. La sua età geologica è di 1,4 milioni di anni; il volume dell'encefalo era di circa 545 cm³, mentre alcuni dei suoi tratti lasciano pensare che questo esemplare rappresenti una variazione nella linea evolutiva in questa specie. Zinjanthropus definition, a genus to which Paranthropus boisei was formerly assigned. Paranthropus boisei, also known as "the Nutcracker man", "the Zinj man" and other nicknames, was a cousin of the human ancestors, that lived during the Pliocene epoch, roughly about 2,000,000 years ago. In 1988, Falk and Tobias demonstrated that hominins can have both an occipital/marginal and transverse/sigmoid systems concurrently or on opposite halves of the skull, such as with the P. boisei specimen KNM-ER 23000. Some skulls are markedly smaller than others, which is taken as evidence of sexual dimorphism where females are much smaller than males, though body size is difficult to estimate given only one specimen, OH 80, definitely provides any bodily elements. However, it is argued that Paranthropus is an invalid grouping and synonymous with [24] Regarding the dural venous sinuses, in 1983, American neuroanthropologist Dean Falk and anthropologist Glenn Conroy suggested that, unlike A. africanus or modern humans, all Paranthropus (and A. afarensis) had expanded occipital and marginal (around the foramen magnum) sinuses, completely supplanting the transverse and sigmoid sinuses. "El Zinjanthropus boisei (1959)"; Questa pagina è stata modificata per l'ultima volta il 20 giu 2019 alle 13:20. [13] Now, the earliest known South African australopithecine ("Little Foot") dates to 3.67 million years ago, contemporaneous with A. [19]:128–132, In a sample of 10 P. boisei specimens, brain size varied from 444–545 cc (27.1–33.3 cu in) with an average of 487.5 cc (29.75 cu in). It was originally placed into its own genus as "Zinjanthropus boisei", but is now relegated to Paranthropus along with other robust australopithecines. … They are collectively known as the ‘robusts’ because of their extremely large jaws and molar teeth. [10] In 2015, based on OH 80, American palaeoanthropologist Michael Lague recommended assigning the isolated humerus specimens KNM-ER 739, 1504, 6020, and 1591 from Koobi Fora to P. A similar scheme may have been in use by P. The enormous cheek teeth (postcanine megadontia) of both sexes would have increased the pressure applied to food. [19] It was also once thought P. boisei cracked open nuts and similar hard foods with its powerful teeth, giving OH 5 the nickname "Nutcracker Man". This is typically considered to be evidence of a high bite force. This could potentially indicate P. boisei was manufacturing the Oldowan tradition and ate meat to some degree. A partial cranium and mandible of Paranthropus robustus was discovered in 1938 by a schoolboy, 70 km south west of Pretoria in South Africa. [18], P. boisei is the most robust of the robust australopithecines, whereas the South African P. robustus is smaller with comparatively more gracile features. [31] The microwearing on P. boisei molars is different than that on P. robustus molars, and indicates that P. boisei, unlike P. robustus, very rarely ever ate hard foods. In 1981, Martin applied equations formulated by ecologists Alton S. Harestad and Fred L. Bunnel in 1979 to estimate the home range and population density of large mammals based on weight and diet, and, using a weight of 52.4 kg (116 lb), he got: 130 ha (320 acres) and 0.769 individuals per square kilometre if herbivorous; 1,295 ha (3,200 acres) and 0.077 individuals if omnivorous; and 287,819 ha (711,220 acres) and 0.0004 individuals if carnivorous. [39], OH 80 was found associated with a mass of Oldowan stone tools and animal bones bearing evidence of butchery. It lived from about 2.6 until about 1.2 million years ago during the Pliocene and Pleistocene epochs in Eastern Africa.It was 4' 6" tall for a male and 4' 1" for a female. The jaws are the main argument for monophyly, but such anatomy is strongly influenced by diet and environment, and could in all likelihood have evolved independently in P. boisei and P. robustus. [6]:120 The P. boisei skull is heavily built, and features a defined brow ridge, receding forehead, rounded bottom margins of the eye sockets, inflated and concave cheek bones, a thick palate, and a robust and deep jawbone. [16] It is possible that P. aethiopicus evolved even earlier, up to 3.3 mya, on the expansive Kenyan floodplains of the time. [6]:109 P. boisei changed remarkably little over its nearly 1 million year existence. [49] Other likely Oldowan predators of great apes include the hunting hyaena Chasmaporthetes nitidula, the sabertoothed cats Dinofelis and Megantereon,[50] and the crocodile Crocodylus anthropophagus. Hominid: Paranthropus Boisei Species: Paranthropus Boisei … Paranthropus boisei had large chewing muscles accompanied by a strong sagittal crest. It lived in Eastern Africa during the Pleistocene epoch from about 2.4 until about 1.4 million years ago. A date of at least 1.95 million years has been obtained for the site.
