According to Begun and Harrison, the Catarrhini split from their New World monkey kin about 44 - 40 Mya, with the first catarrhines appearing in Africa and Arabia, and not appearing in Eurasia (outside Arabia) until 18-17 Mya.

狹鼻小目 （Catarrhini）是 靈長目 簡鼻亞目 中三個小目之一，包含了 舊世界猴 （猴總科）及 猿 （人猿總科）。 後者再細分為 長臂猿科 及 人科。 以往認為 人類 及其已 滅絕 的近親或祖先是一個獨立的科，而 人科 則被分類在 猩猩科 中。

The term catarrhine, meaning ‘narrow, turned-down nose,’ has been used extensively in the literature to describe Old World monkeys and apes. The term platyrrhine, meaning ‘flat nose,’ refers to the flattened muzzle with broadly spaced, laterally flared nares found in …

1987年1月1日 · This paper presents a review of the evolutionary relationships of the early catarrhine primates. The first stage of the analysis involves the reconstruction of the inferred ancestral morphotypes of the major groups of extant anthropoids.

Paleontological evidence demonstrates that early catarrhines (i.e., the clade comprising Old World monkeys, apes and humans) first occurred in Afro-Arabia during the Early Oligocene and were restricted to this zoogeographic region until the Early Miocene.

2023年3月8日 · The history of paleoprimatology effectively begins in the early nineteenth century with the discovery of a fossil from the gypsum quarries of Paris. The Fayum catarrhines are distinguished from other Fayum primates in details of their dental anatomy, but mainly in having only two premolars on each side of each jaw.

Catalan researchers have discovered in the rubbish dump of Can Mata in the Vallès-Penedès basin (Catalonia) a new species of Pliopithecus primate, considered an extinct family of primitive...

2018年10月4日 · Saadanius from the Late Oligocene of Saudi Arabia (28–29 mya) is the earliest catarrhine with a fully developed tube-like ectotympanic, and this feature helps place Saadanius as the sister taxon to crown catarrhines.

2018年7月30日 · This paper addresses key life history traits for this parvorder, focusing primarily on reproduction, growth, lifespan, and social structure. Information on diet, communication, and cognition within the parvorder Catarrhini is covered elsewhere within this encyclopedia and will not be addressed here.

Catarrhini are a group of Old World monkeys that includes humans, apes, and other primates. They are distinguished from other primates by their prominent noses, narrow noses, and relatively large brain volume. Catarrhini species are found in Africa, Asia, and North and South America.
