Yes, and that's only going to keep happening, just like the Amazon city linked to under this article (posted here by eskay a couple of pages back).
As before, ancient human populations were undoubtedly much larger than we have so far estimated, and were decimated over and over again, by pandemics, natural disasters, climate change, and wars, to recover, and then to suffer similar fates again.

A huge Maya city has been discovered centuries after it disappeared under jungle canopy in Mexico.
Archaeologists found pyramids, sports fields, causeways connecting districts and amphitheatres in the southeastern state of Campeche.
They uncovered the hidden complex - which they have called Valeriana - using Lidar, a type of laser survey that maps structures buried under vegetation.
