I don't see how we wouldn't be able to --unless they were able to perfectly able to reprocess everything back into semi-original form. I guess another possibility is if the civilization were so small that coming across artifacts by pure change is very low.
We have evidence of Dinosaurs from over 200MM ya --and even older fossils originally made of perfectly compostable matter.
- adolph 5y agoThe paper addresses these points: As an example, for all the dinosaurs that ever lived, there are only a few thousand near-complete specimens, or equivalently only a handful of individual animals across thousands of taxa per 100,000 years. Conceptually see also: dematerialization refers to the absolute or relative reduction in the quantity of materials required to serve economic functions in society. In common terms, dematerialization means doing more with less. https://en.wikipedia.org/wiki/Dematerialization_(economics) https://en.wikipedia.org/wiki/Dematerialization_(economics) Also: https://www.goodreads.com/book/show/43822733-more-from-less https://www.goodreads.com/book/show/43822733-more-from-less

- adolph 5y agoNot quite, no. The Mesozoic Era lasted from 251 to 66 million years ago. While 66 my is a long time, there may be human processes which "recycle" materials of previous civilizations in ways that make the previous ones harder to discern.
