| Mar 28, 2017 at 17:30 | comment | added | jamesqf | Not true that everything would be out of reach. For instance, there's geologic evidence for (natural) nuclear reactors existing ~1.7 billion years ago: en.wikipedia.org/wiki/Natural_nuclear_fission_reactor Or at a basic tech level, stone arrowheads that were lost in still water (say when hunting ptero-ducks :-)) should fossilize quite well. | |
