Family of catarrhines known from the Miocene of Africa; two genera and three to four species. The most primitive cercopithecoid monkeys known; precede the divergence of the cer copithecines and colobines. Estimated body mass ranges between 7 and 25 kg. Dental formula:; sexually dimorphic canines; possess bilophodont molars, but in general the dental morphology is much more primitive (sharing traits with the hominoids) than found in living cercopithecoids. Recovered postcrania indicate quadrupedalism and it appears these monkeys were semiterrestrial; some workers think that these animals were terrestrial and over time evolved towards a more arboreal habit.
