Dinopithecus ingens

Dinopithecus ("terrible ape") is an extinct genus of very large primates closely related to baboons, that lived during the Pliocene and Pleistocene epochs in South Africa and Ethiopia. [1] [2] It was named by British paleontologist Robert Broom in 1937. [3] The only species currently recognized is Dinopithecus ingens, as D. quadratirostris has been reassigned to the genus Soromandrillus. [4] It is known from several infilled cave sites in South Africa, all of early Pleistocene age, including Skurweberg, Swartkrans (Member 1), and Sterkfontein (Member 4 or 5, but probably member 4). [1] [2] [5]

Description

Dinopithecus ingens was approximately twice the size of the largest living baboons, with males averaging 46 kg (101 lb) and females 29 kg (64 lb), based on estimates from the molar teeth. [6] In some cases males were estimated to reach in maturity a weight of 77 kg (170 lb). [6] The most distinguishing feature of the genus is its large size in comparison to other papionins. The only other papionin species to attain a similar size were Theropithecus brumpti and Theropithecus oswaldi . [6] These, however, are very different from Dinopithecus in their dental morphology. [2] Overall, the skull is similar to that of modern baboons, except that it generally lacks the facial fossae (depressions on the sides of the muzzle and lower jaw) and maxillary ridges (ridges of bone that run along the upper sides of the snout). [2] [4] For these reasons, Dinopithecus is sometimes treated as a subgenus of Papio . [2] [7]

Paleoecology

Most living papionins are omnivorous feeders that consume a wide range of readily digestible plant parts, especially fruits, as well as insects and other invertebrates, and small vertebrates. [8] An analysis of the carbon isotopes from samples of its tooth enamel found Dinopithecus to consume the smallest portion of grass and other savanna-based foods of any South African primate. [9] Analysis of the microwear patterns on the molar teeth showed that they were similar to those of the living yellow baboon ( Papio cynocephalus ), suggesting a broad and eclectic diet. [10] A study of the adaptations of the molar teeth suggested that D. ingens ate a very high percentage of fruit and relatively few leaves. [11]

No bones of the limbs or other parts beyond the skulls and teeth have been attributed to Dinopithecus, so it is impossible to know its mode of locomotion for certain. However, as a papionin of very large size, it most probably spent a significant amount of time on the ground and moved quadrupedally.

<i>Paranthropus</i> Contested extinct genus of hominins

Paranthropus is a genus of extinct hominin which contains two widely accepted species: P. robustus and P. boisei. However, the validity of Paranthropus is contested, and it is sometimes considered to be synonymous with Australopithecus. They are also referred to as the robust australopithecines. They lived between approximately 2.9 and 1.2 million years ago (mya) from the end of the Pliocene to the Middle Pleistocene.

<span class="mw-page-title-main">Gelada</span> Species of Old World monkey

The gelada, sometimes called the bleeding-heart monkey or the gelada baboon, is a species of Old World monkey found only in the Ethiopian Highlands, living at elevations of 1,800–4,400 m (5,900–14,400 ft) above sea level. It is the only living member of the genus Theropithecus, a name derived from the Greek root words for "beast-ape". Like its close relatives in genus Papio, the baboons, it is largely terrestrial, spending much of its time foraging in grasslands, with grasses comprising up to 90% of its diet.

<i>Gigantopithecus</i> Genus of primate

Gigantopithecus is an extinct genus of ape that lived in southern China from 2 million to approximately 300,000-200,000 years ago during the Early to Middle Pleistocene, represented by one species, Gigantopithecus blacki. Potential identifications have also been made in Thailand, Vietnam, and Indonesia. The first remains of Gigantopithecus, two third molar teeth, were identified in a drugstore by anthropologist Ralph von Koenigswald in 1935, who subsequently described the ape. In 1956, the first mandible and more than 1,000 teeth were found in Liucheng, and numerous more remains have since been found in at least 16 sites. Only teeth and four mandibles are known currently, and other skeletal elements were likely consumed by porcupines before they could fossilise. Gigantopithecus was once argued to be a hominin, a member of the human line, but it is now thought to be closely allied with orangutans, classified in the subfamily Ponginae.

<i>Australopithecus africanus</i> Extinct hominid from South Africa

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".

<i>Paranthropus robustus</i> Extinct species of hominin of South Africa

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.

<i>Paranthropus boisei</i> Extinct species of hominin of East Africa

Paranthropus boisei is a species of australopithecine from the Early Pleistocene of East Africa about 2.5 to 1.15 million years ago. 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. It was originally placed into its own genus as "Zinjanthropus boisei", but is now relegated to Paranthropus along with other robust australopithecines. However, it is also argued that Paranthropus is an invalid grouping and synonymous with Australopithecus, so the species is also often classified as Australopithecus boisei.

Parapapio is a genus of prehistoric baboons closely resembling the forest-dwelling mangabeys. Parapapio is distinguished from other Papio by the lack of an anteorbital drop, thin browridges, absence of maxillary fossae or a sagittal crest and only slight sexual dimorphism.

<span class="mw-page-title-main">Gondolin Cave</span> South African cave system

Gondolin Cave is a fossiliferous dolomitic paleocave system in the Northwest Province, South Africa. The paleocave formed in the Eccles Formation dolomites. Gondolin is currently the only described hominin-bearing fossil site in the Northwest Province-portion of the designated Cradle of Humankind UNESCO World Heritage Site. The cave is located on privately owned land and is not accessible to the public. As is the case with other South African Paleo-cave systems with Pliocene and/or Pleistocene fossil deposits, the system was mined for lime during the early 20th century. As a result, the system has been heavily disturbed and consists of only a small active cave, a series of in situ remnant cave deposits, and extensive dumpsites of ex situ calcified sediments produced during mining activities.

Haasgat is a fossiliferous South African paleocave located in the Cradle of Humankind UNESCO World Heritage Area, approx. 20 kilometres (12 mi) northeast of the hominin-bearing sites of Sterkfontein and Swartkrans and approx. 60 kilometres (37 mi) north-northwest of the City of Johannesburg. It is located on private land and is not accessible by the public.

<i>Theropithecus oswaldi</i> Extinct species of Old World monkey

Theropithecus oswaldi is an extinct species of Theropithecus from the early to middle Pleistocene of Kenya, Ethiopia, Tanzania, South Africa, Spain, Morocco and Algeria. The species went extinct in South Africa around 1.0 Ma. Having existed alongside hominins like Homo erectus, it is likely that conflict with early humans played a role in their extinction as a site has been found with many juveniles butchered.

<i>Cercopithecoides</i> Extinct genus of Old World monkeys

Cercopithecoides is an extinct genus of colobine monkey from Africa which lived during the latest Miocene to the Pleistocene period. There are several recognized species, with the smallest close in size to some of the larger extant colobines, and males of the largest species weighed over 50 kilograms (110 lb).

Pliopapio is an extinct genus of Old World monkey known from the latest part of the Miocene to the early Pliocene Epochs from the Afar Region of Ethiopia. It was first described based on a very large series of fossils from the site of Aramis in the Middle Awash, which has been dated by 40Ar/39Ar to 4.4 million years old. It has since been found from similarly aged sediments at Gona, approximately 75 km to the North. Additional fossils from the Middle Awash extend its known time range back to at least 5.3 million years ago. There is only one known species, Pliopapio alemui.

Rhinocolobus is an extinct genus of monkey closely related to modern colobus monkeys. It lived in eastern Africa during the Plio-Pleistocene, existing as recently as 1.5 million years ago.

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.

Minnaar's Cave, or simply Minnaar, is a palaeontological site located in the Cradle of Humankind World Heritage Site, Gauteng province, South Africa. Lost after its discovery in the 1930s, its location was rediscovered in 2009. It is known for its well-preserved jackal skulls, dating to the Plio-Pleistocene at least 2 million years ago.
