The cranial capacity is estimated at 420 cubic centimeters (cc), which is pretty small, but within the estimated A. africanus range of variation. Found between 3.85 and 2.95 million years ago in Eastern Africa (Ethiopia, Kenya, Tanzania), this species survived for more than 900,000 years, which is over four times as long as our own species has been around. DATES: 3 to 2.3 million years ago (Tobias, 1973) SITES: Taung, Makapansgat, Sterkfontein, and Gladysvale, South Africa.

Research Citations & Bibliography Captions (8) Australopithecus africanus fossils have been found at a number of localities in South Africa. Dates to: 3.5 MYA. A. africanus and Australopithecus afarensis have similar post-cranial morphologies and both exhibit a high degree of sexual dimorphism. It was originally thought to be a middle-aged female because of the gracile nature of the skull. Both fossils were later classified as Australopithecus africanus. It provides the first fossil evidence as the first and earliest biped. Both fossils were later classified as Australopithecus africanus. This specimen is a juvenile that is dated 3.0-2.3 million years ago. The type specimen for A. africanus is the Taung 1, or the “Taung Child”, which was found at Taung (South Africa) dates between 3 million and a little less than 2.5 million years ago. africanus was anatomically similar to Au. Fig.8: Skull of Zinjanthropus or Australopithecus boisei (Yale Peabody Museum cast; photo: Athena Review) Brain size or cranial capacity was about 450–550 cc, similar to that of other australopithecines. Considered to have lived 2.5 MYA, the Australopithecus africanus Skull Sts 5 "Mrs. Ples" was discovered in 1947 by R. Broom and J. Robinson in Sterkfontein, Transvaal, South Africa. Australopithecus africanus: The man-ape of South Africa. It was later that the discoverers realized this was actually a male cranium. Sites: South Africa: Taung and Sterkfontein Age: 3.3 to 2 mya Type specimen: Taung child Specimens: Mrs Ples (Sts 5), Sts 14, Sts 71, Sts 36, Sts 71, Stw 505. (The dental arch of Au. Mrs. Ples, whose cranial capacity is only about 485 cubic centimetres, was one of the first fossils to reveal that upright walking (bipedal locomotion) had evolved well before any significant growth in brain size. Australopithecus africanus (česky též Australopiték africký) je druh vyhynulého hominida, žijící na přelomu pliocénu a pleistocénu, před 3 - 2 miliony let v jižní Africe, na území dnešní Jihoafrické republiky.Ačkoliv není geologicky nejstarším australopitékem, byl rozeznán jako první a je tudíž typovým druhem celého rodu. With a cranial capacity of 450 cubic centimeters, this is one of the largest cranium we have seen thus far in these early species of hominins. [12] The teeth are relatively large in comparison to body size of A. anamensis.The back teeth are large relative to the front teeth. Flashcards. Between bipedalism, the reduction of the canines and overall robusticity, the remains of Australopithecus africanus have given paleoanthropologists reason to believe this is the start of the hominid lineage. The cranial capacity is about 485 cubic centimeters. Au. It was not until other, adult, specimens were discovered in southern Africa during the next twenty years that Australopithecus africanus began to gain acceptance in the established scientific community. This skull is more gracile than Au. It is the first species to walk upright! The time period for Australopithecus africanus is 3.3 to 2.1 million years BCE (before the common era). afarensis ranges from 380–530 cc (23.2–32.3 cubic inches), about one-third the size of that of a modern human. This is the skull of a juvenile, but provides the morphologies to support it's classification as africanus. The first specimen was collected in 1924. Schwartz JH and Tattersall I. Australopithecus africanus was once considered to be a direct ancestor of modern humans but new finds have challenged this position. Africanus had a slender physique and is often believed to be an immediate ancestor of the present human being. KNM-KP 29281 is considered the type specimen and consists of a mandible with teeth, but lacking ascending rami.

Funding for eFossils was provided by the Longhorn Innovation Fund for Technology (LIFT) Award from the Research & Educational Technology Committee (R&E) of the IT governance structure at The University of Texas at Austin. While st… While the brain was small relative to later species, Au. Australopithecus africanus Australopithecus africanus was an early hominid, an australopithecine, who lived between 2-3 million years ago in the Pliocene.1 In common with the older Australopithecus afarensis, A. africanus was slenderly built, or gracile, and was thought to have been a direct ancestor of modern humans. The dry environment of the South African cave where the fossil was found helped to preserve the face, mandible and even in nearly perfect endocast of the brain. [Google Scholar] Conroy GC, Weber GW, Seidler H, et al. Cranial capacity is a measure of the volume of the interior of the skull of those vertebrates who have a brain. A. africanus fossil remains have been found in South Africa at locations such as Sterkfontein, Makapansgat, and Taung. A specimen of Australopithecus africanus nicknamed "Taung Child".

Learn. This method was used because of the lack of volcanic ash present at the site did not allow an absolute dating method, such as 40Ar/39Ar, to be used on the stratigraphic layers. africanus had a rounder cranium housing a larger brain and smaller teeth, but it also had some ape-like features including relatively long arms and a strongly sloping face that juts out from underneath the braincase with a pronounced jaw. PLAY. Australopithecus africanus is an early fossil hominin known from several localities in South Africa, most notably Swartkrans Cave. Write. SPECIMENS: many individuals. It is known as the "Taung child." afarensis, Au. Australopithecus africanus: The man-ape of South Africa. A partial adult skeleton was also found in Sterkfontein, South Africa in 1947 and has been dated to be approximately 2.5 million years old.To be able to find this much of a skeleton was quite rare because of the delicacy of the vertebrae, pelvis and ribs. Relationships with other species. Raymond Dart studied this specimen and recognized that it was a juvenile hominin. However, A. africanus' derived cranial morphology includes a higher forehead, slightly larger cranial capacity of approximately 461 cc, less pronounced brow ridge, smaller canines and large molars. In 1925 South African anthropologist Raymond Dart coined the genus name Australopithecus to identify a child’s skull recovered from mining operations at Taung in South Africa.He called it Australopithecus africanus, meaning “southern ape of Africa.” From then until 1960 almost all that was known about australopiths came from limestone caves in South Africa. Australopithecus africanus is the name given to early hominid that lived between 2 and 3 million years ago (Aiello & Dean, 1990).A. In 1924, Raymond Dart found the first australopith fossil and named it Autralopithecus africanus, or "African southern Ape". Already the cranial capacity was greater than a full grown chimp’s and the Taung child was only six years old. found in South Africa in three sites: Sterkfortein, Swarartkrans, Kromdrgai described as a more "robut" version of the Australopithecus; Australopithecus … The most commonly used unit of measure is the cubic centimetre (cm 3). This "man-ape of South Africa" has many human-like characteristics including: a higher forehead, delicate cheekbones and a less prognathic face compared to apes. The estimated cranial capacity for the juvenile Taung 1 is 405 cc, with an estimated adult size of 440 cc, which is relatively much larger than the adult chimpanzee mean of about 400 cc. Australopithecus africanus. The inferiorly placed foramen magnum, and the morphology of the pelvis demonstrates that A. afarensis was bipedal. Introduction.

By having the pelvis, the specimen was unequivocally identified as bipedal and different from the ape morphologically. Image from: http://i17.photobucket.com/albums/b73/karenw44, This is the cranium of an Australopithecus africanus that was nicknamed "Mrs. Ples" because it was thought to be female. Living 3.0-2.3 million years ago, Australopithecus africanus has provided us with some soild information as to who our human ancestors are.The method of biostratigraphy, a relative dating method, was used in southern Africa to date the remains of Au. eFossils is a collaborative website in which users can explore important fossil localities and browse the fossil digital library. Australopithecus africanus had a cranial capacity of about 450 cc, a brain size that puts it on a par with a rather brainy modern chimpanzee. lifestyle - … The first name is the genus and the second is the species (the first word is always capitalized, the second is not) hence; Australopithecus africanus. Experts who argue Australopithecus africanus was an ancestor of modern humans say it was somewhat more human-like with respect to cranial characteristics than was Australopithecus afarensis. Mrs. Ples, whose cranial capacity is only about 485 cubic centimetres (cc), was one of the first fossils to reveal that upright walking (bipedal locomotion) had evolved well before any significant growth in brain size. very small cranial capacity (volume of the brain case), 405 cc - 440 cc in the adult. Cranial capacity. This skull has a hypoplastic midface and a fairly large cranial capacity. The nickname Mrs. Ples was derived from the scientific designation Plesianthropus transvaalensis (near-man from the Transvaal), initially given to the skull by Dr. Broom; the nickname itself was coined by young coworkers of Dr. Broom. africanus. Science 280, 1730–1731. CHARACTERISTICS: Skull: The braincase of Australopithecus africanus was higher and rounder than in A. afarensis and less apelike. The fossil was discovered in 1994 at Kanapoi and has an estimated age of 4.4 million years. However, A. africanus' derived cranial morphology includes a higher forehead, slightly larger cranial capacity of approximately 461 cc, less pronounced brow ridge, smaller canines and large molars. The word africanus is a Latinised form of the word ‘Africa’ and indicates the continent where this species was found. 3MYA. Dart RA. The Taung child’s cranial capacity was measured to be at least 114 mm, 3 mm greater than an adult chimp (Dart 1925). The Taung Child had a cranial capacity of 340 cm 3, living mainly in a savanna habitat. The Australopithecus anamensis tibia indicates bipedalism. afarensis, with a combination of human-like and ape-like features.Compared to Au. Gravity. The "Taung Child" was discovered by Raymond Dart in 1924. Image from: http://ana215fossils.weebly.com/mrs-ples.html, This is a partial adult skeleton that was found in South Africa that confirms paleoanthropologists belief that Australopithecus africanus was a biped.

Increase of about 2 over comparably sized apes; Australopithecus robustus. Originally thought by Broom to be a female, Sts 5 is now considered by most to be a male. Dart was certain that the brain size of a full-grown Au. characteristics. With a cranial capacity of 450 cubic centimeters, this is one of the largest cranium we have seen thus far in these early species of hominins. The complete deciduous dentition is present as well as all four first molars 4. Both fossils were later classified as Australopithecus africanus. Science 247, 838–841.
