Another notable dental characteristic is the same dental formula as modern-day anthropoids, yet the molars bear a closer resemblance to Old World Monkeys than to apes or humans.
Many paleoanthropologists believe this supports Aegyptopithecus as a common ancestor to monkeys, apes, and humans.
Aegyptopithecus is not only an important find because it could very possibly be an ancestral lineage to humans, but also because it closes the gap of missing information between Eocene and Miocene fossil hominoids and provides paleoanthropologist a more complete picture of hominin evolution. Aegyptopithecus :: overview. Retrieved from johnhawks. Proto-hominids: Miocene Hominoids. Based on this information, it has been determined that Aegyptopithecus zeuxis may have lived in large, complex social units.
The few postcranial remains that have been discovered indicate that this propliopithecid was a slow moving arboreal quadruped, similar to the New World howler monkey, that was capable of leaping and some suspensory behavior. You save. Quantity: Increase Quantity: Decrease Quantity:. MicroCT scans of a male cranium recovered in [Egyptian Geological Museum, Cairo CGM ] reveal that previous estimates of its endocranial volume were too large.
Thus, some amount of encephalization evolved independently in platyrrhine and catarrhine anthropoids, and the relative brain size of the last common ancestor of crown Anthropoidea was probably strepsirrhine-like or smaller. Although a unique pattern of craniofacial sexual dimorphism may have characterized advanced stem and basal crown catarrhines, expression of various allegedly "discrete" craniofacial features may have been intraspecifically variable in early catarrhine species due to high levels of dimorphism and so should be treated with caution in phylogenetic analyses.
