Lost Ethiopian town comes from an ancient empire that rivalled Rome

I have a feeling that there's a lot of history that will be uncovered in Africa, particularly as many countries on the continent get richer and have the resources for stuff like archaeologists to learn more about the past.

In my recent history kick it was really frustrating the black hole of African history (besides the egyptians, obviously). But we're learning more about stuff like Ethiopian civilization, and obviously Great Zimbabwe, what else is out there buried waiting to be found?
