By 17 to 15 million years ago, primates existed that paleontologists can definitely identify as apes.
In fact, so many fossil apes are known from the AMONG THE PRIMATES 37 Proconsul, a possible ancestor of apes, lived in Africa approximately 20 million years ago.
Only in Africa, which remained covered with thick trop- ical forests, did primates continue to flourish. Fossil deposits from Fayum, Egypt, show that North Africa had a large and diverse group of these species between 36 and 31 million years ago.
