Aegytopithecus zeuxis, skull reconstruction Kentrosaurus Most ammonites are homomorphAegyptopithecus, which means "Egyptian Monkey" is an early fossil catarrhine that predates the divergence between hominoids (apes and humans) and cercopithecids (Old World monkeys). It is known from a single species, Aegyptopithecus zeuxis, which lived around 30 million years ago in the early part of the Oligocene epoch. It likely resembled modern day New World monkeys and was about the same size as a modern howler monkey, which is about 56 to 92 cm
