Let’s grant that some types of the landscape are more likely to contain fossils than other parts. Still, unless it’s something like the La Brea tar pits, you would have to think even in fossil-prone areas, only a minescule percentage of the area is actual fossil and the rest is just boring old earth and rock. So even if you identify a place which is more likely than average to contain fossils, you would have to do an enormous amount of digging to even have a remote chance of finding anything. And it’s not like you can use heavy equipment either, because you would just destroy whatever it is you’re digging for.
I’m aware that many fossil finds are the result of random people digging for other reasons and just finding fossils. But is that all of them? My impression is that there are scientists who specialize in finding fossils, and I imagine it’s something more than just getting in contact with a lot of accidental fossil finders. Or is that wrong?
