The parvorder Catarrhini / k æ t ə ˈ r aɪ n aɪ / (known commonly as catarrhine monkeys, Old World anthropoids, or Old World monkeys) consists of the Cercopithecoidea and apes (Hominoidea). In 1812, Geoffroy grouped those two groups together and established the name Catarrhini, "Old World monkeys", (" singes de l'Ancien Monde " in French ).
In 2010, Saadanius was described as a close relative of the last common ancestor of the crown catarrhines, and tentatively dated to 29–28 million years ago, helping to fill an 11-million-year gap in the fossil record. [9] Notable species also include Nsungwepithecus gunnelli and Rukwapithecus fleaglei of the Oligocene. [10]
Propliopithecoidea is a superfamily of catarrhine primates that inhabited Africa and the Arabian Peninsula during the Early Oligocene about 32 to 29 million years ago. Fossils have been found in Egypt, Oman and Angola.
About 40 million years ago, the Simiiformes infraorder split into the parvorders Platyrrhini (New World monkeys) and Catarrhini (apes and Old World monkeys) somewhere on the African continent. [5] Platyrrhini are currently conjectured to have dispersed to South America on a raft of vegetation across the Atlantic Ocean during the Eocene epoch ...
Aegyptopithecus is thought to have been an arboreal quadruped due to the distal articular region of the femur, which is deeper than that of "later" catarrhines. [2] Also, based on overall femoral morphology, A. zeuxis is thought to have been robust. [2] The phalanges of the hands and feet suggest powerful grasping consistent with arboreal ...
In the long term, the greatest changes in the Solar System will come from changes in the Sun itself as it ages. As the Sun burns through its hydrogen fuel supply, it gets hotter and burns the remaining fuel even faster. As a result, the Sun is growing brighter at a rate of ten percent every 1.1 billion years.

The simians include catarrhines (Old World monkeys and apes, including humans), and the platyrrhines (New World monkeys). Haplorhini was proposed by Pocock in 1918 when he realized the tarsiers were actually sister to the monkeys rather than the lemurs, also following findings of Hugh Cuming 80 years earlier and Linnaeus 160 years earlier.
The type specimen of C. browni, CGM 41885, is a right mandible discovered in 1987 by Mark Brown.The mandible was found with intact molars 1-3, and premolars 3-4, and alveoli are present for a canine tooth and incisors 1-2, indicating a lower dental formula of 2.1.2.3.
