Re: Pre-human civilizations on Earth
Unless you're suggesting their entire genus burst forth into being with nuclear reactors and all choosing to cremate, population density really isn't an issue.
Even then, accidents, crime, and predation will occur leading to hidden corpses.

Re: Pre-human civilizations on Earth
Most of which will vanish without a trace. On the other hand, you can pretty much tell something is up without actually finding remains. A civilization as advanced as ours would show up in the fossil record as a mass extinction event, plus in the geologic record as some really weird strata.

Re: Pre-human civilizations on Earth
The hypothesis does not specify how large the civilization is nor it's terrestrial origins.

Re: Pre-human civilizations on Earth
Of course. But those things can make any other logical extrapolations moot. I tend to believe that the base rules should be agreed upon before such things are added.

Re: Pre-human civilizations on Earth
What if they're fairies? They live in mysterious mounds and mystical places.

Re: Pre-human civilizations on Earth
Should depend on exposure to elements (water and various ions carried in water). If it gets buried in a dry area, it will probably just sit there.
