"However, I wasn't quite sure what it had to do with ancient geography resources."

Hence my question, how ancient do you want to get?

My suggestions dealt broadly with break up of supercontinents and the like, which I suppose you could call palaeogeography rather than ancient geography.

My apologies if I have misconstrued your thread.

Perhaps you can elaborate / define on 'ancient' geography?
Do you mean, perhaps, something like the expansion of the Roman Empire?
