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 ).
Evolution of the amniotic egg allows the amniotes to reproduce on land and lay shelled eggs on dry land. They did not need to return to water for reproduction nor breathing. This adaptation and the desiccation-resistant scales gave them the capability to inhabit the uplands for the first time, albeit making them drink water through their mouths.
Saadanius had a longer face than living catarrhines and lacked the advanced frontal sinus found in living catarrhines. However, it had a bony ectotympanic and teeth comparable to those of living catarrhines. Its discovery provided new information about the early evolution of catarrhines.
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.
The distinction of catarrhines from platyrrhines depends on the structure of the rhinarium, and the distinction of Old World monkeys from apes depends on dentition (the number of teeth is the same in both, but they are shaped differently). In platyrrhines, the nostrils face sideways, while in catarrhines, they face downward.
Parvorder Catarrhini: Old World monkeys, apes (including humans) The arrangement of the New World monkey families, indeed the listing of which groups consist of families and which consist of lower taxonomic groupings, has changed over the years.
Things you might see at the beach (near the water). 2. Minor damage. 3. These noises are usually associated with a particular device. 4. The words in this category precede a common four-letter ...
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 ...
