Excerpted from here:

I'm guessing that what's meant by late Middle Eocene is the Lutetian (http://en.wikipedia.org/wiki/Lutetian)?

If multiple Asian anthropoid clades colonized Africa, did colonization take place synchronously or in a temporally staggered fashion? ... it must be noted that two of the Asian mammal clades (anthropoid primates and hystricognathous rodents) that successfully colonized Africa during the early Cenozoic were able to continue their patter of intercontinental dispersal across the South Atlantic to invade South America. Recent paleontological discoveries in Peru indicate that (at least) hystricognathous rodents achieved this feat remarkably early, during the middle Eocene. ... Therefore, the middle Eocene appears to be a critical interval for the intercontinental dispersal of land mammals, meriting additional fieldwork on all southern continents.
