Gladysvale Cave is a fossil-bearing breccia filled cave located about 13 kilometres (8.1 mi) northeast of the well-known South African hominid-bearing sites of Sterkfontein and Swartkrans and about 45 kilometres (28 mi) north-northwest of Johannesburg, South Africa. It is situated within the Cradle of Humankind World Heritage Site and is itself a South African National Heritage Site. [1]
Gladysvale is the first cave that Robert Broom visited in the Transvaal in his mid-1930s search for a hominid-bearing cave nearer to Johannesburg than Taung. [2] He visited Gladysvale after a butterfly collector from the Transvaal Museum reported a "human mandible" in the wall of the cave. When Broom arrived at the cave the mandible was gone. Sterkfontein soon lured Broom away from the site. In 1946 Phillip Tobias led a student expedition to the site where a fine baboon fossil was recovered. [3] In 1948 Frank Peabody of the Camp-Peabody expedition from the United States spent several weeks at Gladysvale but failed to find any hominid remains. The site was lost from scientific memory until it was re-opened by Lee Berger and Andre Keyser in 1991. Within a few weeks of excavation the first hominid remains were discovered – two teeth of Australopithecus africanus . This discovery made Gladysvale the first new early hominid site to be discovered in South Africa since 1948 (when the last site – Swartkrans – was discovered by Robert Broom). [2]
Since the discovery of these teeth more than a quarter of a million fossils have been recovered from Gladysvale during excavations conducted by joint teams from the University of the Witwatersrand, the University of Zurich and Duke University. [4]
Many thousands of fossils have been recovered from the Gladysvale deposits including rare remains of hominids. From the Gladysvale external deposits, almost a quarter of a million bones have been recovered since excavations began in 1992. There are many millions of bones still in place in the cave. Fossils recovered include antelope, giant zebra, carnivores including extinct wolves, monkeys and hominids attributed to Australopithecus africanus and early Homo . [4]
Tools have also been found with the most spectacular being an Acheulean handaxe (pictured), recovered from 1 million year old sediments.
Gladysvale has become well known for its exceptional horizontally-bedded stratigraphy and has been the site of the testing of many of the absolute dating techniques which have proved successful on the hard to date breccias of the South African fossil-bearing caves. The site is presently divided into three cave systems with the upper cave holding the Gladysvale Internal Deposits and an External Deposit (pictured in 3-D). Gladysvale was one of the first sites in Africa to be 3-D digitally mapped by Peter Schmid and students from the University of Zurich. [4]
The Gladysvale sequence has been dated using a combination of biostratigraphy, palaeomagnetism (Andy Herries, La Trobe University, Australia), electron spin resonance and uranium series dating (Robyn Pickering, U. Melbourne, Australia). The youngest deposits are thought to be around 54,000 years old while the oldest deposits that are the likely source of the Au. africanus fossils are around 2.4–2.0 million years old. The Gladysvale External deposits contain extensive faunal remains and date to between 780,000 and 530,000 years ago. An Acheulian handaxe was recovered from internal deposits older than the Bruhnes-Matuyama boundary at 780,000 years.
The Cradle of Humankind is a paleoanthropological site that is located about 50 km (31 mi) northwest of Johannesburg, South Africa, in the Gauteng province. Declared a World Heritage Site by UNESCO in 1999, the site is home to the largest known concentration of human ancestral remains anywhere in the world. The site currently occupies 47,000 hectares (180 sq mi) and contains a complex system of limestone caves. The registered name of the site in the list of World Heritage Sites is Fossil Hominid Sites of South Africa.
Sterkfontein is a set of limestone caves of special interest in paleoanthropology located in Gauteng province, about 40 kilometres (25 mi) northwest of Johannesburg, South Africa in the Muldersdrift area close to the town of Krugersdorp. The archaeological sites of Swartkrans and Kromdraai are in the same area. Sterkfontein is a South African National Heritage Site and was also declared a World Heritage Site in 2000. The area in which it is situated is known as the Cradle of Humankind. The Sterkfontein Caves are also home to numerous wild African species including Belonogaster petiolata, a wasp species of which there is a large nesting presence.
Mrs. Ples is the popular nickname for the most complete skull of an Australopithecus africanus ever found in South Africa. Many Australopithecus fossils have been found near Sterkfontein, about 40 kilometres (25 mi) northwest of Johannesburg, in a region of Gauteng now designated as the Cradle of Humankind World Heritage Site. Mrs. Ples was discovered by Robert Broom and John T. Robinson on April 18, 1947. Because of Broom's use of dynamite and pickaxe while excavating, Mrs. Ples's skull was blown into pieces and some fragments are missing. Nonetheless, Mrs./Mr. Ples is one of the most "perfect" pre-human skulls ever found. The skull is currently held at the Ditsong National Museum of Natural History in Pretoria.
Taung is a small town situated in the North West Province of South Africa. The name means place of the lion and was named after Tau, the Chief of the Legoya or Bataung people. Tau is the Tswana word for lion.
Australopithecus africanus is an extinct species of australopithecine which lived between about 3.3 and 2.1 million years ago in the Late Pliocene to Early Pleistocene of South Africa. The species has been recovered from Taung, Sterkfontein, Makapansgat, and Gladysvale. The first specimen, the Taung child, was described by anatomist Raymond Dart in 1924, and was the first early hominin found. However, its closer relations to humans than to other apes would not become widely accepted until the middle of the century because most had believed humans evolved outside of Africa. It is unclear how A. africanus relates to other hominins, being variously placed as ancestral to Homo and Paranthropus, to just Paranthropus, or to just P. robustus. The specimen "Little Foot" is the most completely preserved early hominin, with 90% of the skeleton intact, and the oldest South African australopith. However, it is controversially suggested that it and similar specimens be split off into "A. prometheus".
Paranthropus robustus is a species of robust australopithecine from the Early and possibly Middle Pleistocene of the Cradle of Humankind, South Africa, about 2.27 to 0.87 million years ago. It has been identified in Kromdraai, Swartkrans, Sterkfontein, Gondolin, Cooper's, and Drimolen Caves. Discovered in 1938, it was among the first early hominins described, and became the type species for the genus Paranthropus. However, it has been argued by some that Paranthropus is an invalid grouping and synonymous with Australopithecus, so the species is also often classified as Australopithecus robustus.
Swartkrans is a fossil-bearing cave designated as a South African National Heritage Site, located about 32 km (20 mi) from Johannesburg. It is located in the Cradle of Humankind World Heritage Site and is notable for being extremely rich in archaeological material, particularly hominin remains. Fossils discovered in the limestone of Swartkrans include Homo ergaster, Paranthropus and Homo habilis. The oldest deposits present at the site are believed to be between 1.9 and 2.1 million years old.
Ronald John Clarke is a paleoanthropologist most notable for the discovery of "Little Foot", an extraordinarily complete skeleton of Australopithecus, in the Sterkfontein Caves. A more technical description of various aspects of his description of the Australopithecus skeleton was published in the Journal of Quaternary Science.
STS 14 is a fossilized partial skeleton of the species Australopithecus africanus. It was discovered at Sterkfontein, South Africa by Robert Broom and John T. Robinson in August 1947, and is estimated to be about 2.5 million years old.
The Evolutionary Studies Institute (ESI) is a paleontological, paleoanthropological and archeological research institute operated through the Faculty of Science of the University of the Witwatersrand, Johannesburg, South Africa. Previously known as the Bernard Price Institute for Palaeontological Research (BPI) it was renamed the Evolutionary Studies Institute in 2013 to better showcase the scope of its research.
Cooper's Cave is a series of fossil-bearing breccia filled cavities. The cave is located almost exactly between the well known South African hominid-bearing sites of Sterkfontein and Kromdraai and about 40 kilometres (25 mi) northwest of Johannesburg, South Africa and has been declared a South African National Heritage Site.
Motsetsi Cave is a fossil-bearing breccia filled cavity located about 14 kilometres (8.7 mi) east of the well known South African hominid-bearing sites of Sterkfontein and Kromdraai and about 45 kilometres (28 mi) north-northwest of Johannesburg, South Africa. Motsetsi has been declared a South African National Heritage Site.
Plovers Lake Cave is a fossil-bearing breccia-filled cavity in South Africa. The cave is located about 4 km southeast of the well-known South African hominid-bearing sites of Sterkfontein and Kromdraai and about 36 km northwest of Johannesburg. Plovers Lake has been declared a South African National Heritage Site.
Kromdraai is a fossil-bearing breccia-filled cave located about 2 kilometres (1.2 mi) east of the well-known South African hominid-bearing site of Sterkfontein and about 45 kilometres (28 mi) northwest of Johannesburg, South Africa. It is situated within the Cradle of Humankind World Heritage Site and is itself a South African National Heritage Site.
Makapansgat is an archaeological location within the Makapansgat and Zwartkrans Valleys, northeast of Mokopane in Limpopo province, South Africa. It is an important palaeontological site, with the local limeworks containing Australopithecus-bearing deposits dating to between 3.0 and 2.6 million years BP. The whole Makapan Valley has been declared a South African Heritage Site. Makapansgat belongs to the Cradle of Humankind.
Malapa is a fossil-bearing cave located about 15 kilometres (9.3 mi) northeast of the well known South African hominid-bearing sites of Sterkfontein and Swartkrans and about 45 kilometres (28 mi) north-northwest of Johannesburg, South Africa. It is situated within the Cradle of Humankind World Heritage Site.
The Drimolen Palaeocave System consists of a series of terminal Pliocene to early Pleistocene hominin-bearing palaeocave fills located around 40 kilometres (25 mi) north of Johannesburg, South Africa, and about 6 kilometres (3.7 mi) north of Sterkfontein in the UNESCO World Heritage Site Cradle of Humankind.
André Werner Keyser, was a South African palaeontologist and geologist noted for his discovery of the Drimolen hominid site and of numerous hominid remains.
The Osteodontokeraticculture (ODK) is a hypothesis that was developed by Prof. Raymond Dart, which detailed the predatory habits of Australopith species in South Africa involving the manufacture and use of osseous implements. Dart envisaged Australopithecus africanus, known from Taung and Sterkfontein caves, and Australopithecus prometheus from Makapansgat, as carnivorous, cannibalistic predators who utilized bone and horn implements to hunt various animals, such as antelopes and primates, as well as other Australopiths.
Bolt's Farm is a palaeontological site in the Cradle of Humankind World Heritage Site, Gauteng province, South Africa. With more than 30 fossil deposits dating back 4.5 Ma, it is one of the oldest sites currently discovered in the Cradle of Humankind. It consists of multiple cavities, pits, and quarries, where caves have eroded away, exposing their fossiliferous interiors. Although this site has not yet yielded the hominid fossils for which the Cradle of Humankind is known, Bolt's Farm is still an important source of fossils from various species of Early Pliocene and Plio-Pleistocene fauna, including primates and big cats.
