The Congo Basin includes a huge area of rocks that are the right age for primate fossils: Quaternarny (white) and Cenozoic (yellow) on this map. That area is teeming with mammals, yet a mammal fossil has never been reported from there.
And that is not because people are not looking. Poor and hungry people are digging and looking all the time in those sedimentary rock layers, trying to find diamonds and little nuggets of gold. The artisanal excavations are extensive. A primate tooth would be worth its weight in gold. You can be sure that if there were fossil teeth there of any mammal, people would report them and get paid.
