Is There Any Evidence Of Significant "Lost Knowledge" That Is Currently Being Sought After By Historians/Archaeologists?

Obviously not anything on the scale of Atlantis, or the like (I would assume?), but has there been any significant influence on a large cohort of people searching for a groundbreaking discovery that would change our view about the past/present/future? Sorry if this has been asked before!

This is just a side question, but since we're talking about ancient texts, I figured to ask it here versus making it a thread: how much about our perception of Roman history would change if all of Livy's Ab Urbe Condita was still intact?

Thanks. It just seems strange to me that there won't be major info that only Livy recorded that became lost.
