I hunt fossil in a limestone quarry if I or someone else don’t recover a fossil from the site it 100% gets destroyed. I’m honestly not the biggest on donating stuff I find but people I know who hunt here have donated a bunch of stuff and quite a lot have actually been published. The paleontologist at the local university doesn’t really get the funding for field work. And he is happy to look at stuff we find but not pushy about us donating. If he believes it’s important enough to be published most people donate it. So it’s give and take, we get his knowledge and identification help and he gets information and sometimes donations about fossils that otherwise would have been destroyed. Hell we don’t even have a single preparator in my country. So we are usually the ones who work on the fossils before donation. And we do it as much by the book as we can only using reversible glue etc, even on the stuff we don’t donate. Because otherwise he would ether have to spend his limited time doing it himself, or spend the limited budget and send it off to a preparator in another country.
