ANTC99H3 Lecture Notes - Lecture 11: Semicircular Canals, Gradualism, Aegyptopithecus
Document Summary
During the oligocene there are low levels of diversification (extinction of primates) During the late oligocene there were the first new world monkeys. During the miocene the area became heavily forested and there was an increase in primate species. During the late miocene the land became dry but the cercopithecoids did well due to their terrestrial locomotion and bilophodont teeth. Late eocene to the early oligocene most primates ate bugs and fruits. The modern day diet of cercopithecoids consists of leaves (they are low energy and have less cost) Macaques can live in many different kinds of environments. 18. 10 p. 405 dietary change in catarrhines colobines cercopithecine lecture 11 patterns and subfossil lemurs. Catarrhines went from being arboreal to semi-terrestrial and arboreal. There is also a change in arboreal catarrhines. In the early oligocene most were quadrupedal arborealists but some have developed suspensory behaviours (larger primates) During the eocene and the olgocene the primates were smaller.
