Where I'm looking for fossils

Thought i'd ask about an area I revisited to see if it seems like a good spot to start looking for fossils. It's a mine dump, most of it seems to be shale I think (is it?) Means I don't I have to dig, but most of it is pretty shattered.

Thanks, actually he already messaged me about that, said he doesn't know much about northern Minnesota but told me of someone who might.

Where abouts in Northern Minn are you looking?

Much of that area is Precambrian in age, which usually means "no fossils" but I would never say "don't look in Precambrian rocks", as there is always the possibility - however small - that you'll find something like stromatolites or Grypania or some other interesting thing.

There is a good geological map (pdf) on Wikipedia.

Mesabi Iron range. I kinda knew up here didn't have the liveliest prehistory but wasn't sure (also I assumed shale=fossils 100%), though I've heard the Mississippi river even up here has a good "stock" of things like trilobites, which isn't far from here. And about the map, I don't know what any of it means or how to read it. (im really new at this)

About the map, all you need to know is to look for colors/letters that indicate Paleozoic or Mesozoic (see the top of the key in upper right) and check out those areas. No guarantee that you'll find anything in any exposures of such but if you're looking for normal invertebrate, vertebrate and plant fossils, those are the areas to try. I see there is some Cretaceous (K-) adjacent to the MIR, but I haven't heard of any fossils being found there so I wouldn't bet on that. I would definitely follow any leads like those you mention.

I doubt that this statement is true if you are referring to north of the Twin Cities. Try checking this out: Hill Annex Mine Fossil Gallery - Minnesota Cretaceous Fossils . It may help in your understanding of fossils in your area.

ok, I kinda thought that'd be the case, but was hoping I was wrong :/  But I know of hill annex, it's like 20 minutes from where I live, in calumet. I'll check that out, thanks.

WAIT, those little snail shells are fossils?! I've just been leaving them, even smashing them thinking they were just dead modern snail shells...

Aha!

The snails you smashed were empty, modern-looking ones? The ones I see on that website Mike mentions are sediment-filled, clearly fossils.

I know it's been nearly two weeks, but ill just say it, turns out that the Hill Annex fossil park is a part of that cretaceous area, and is the site where one of the only dino fossils was found in MN, a single theropod claw. I live just 10 minutes away (but im just outside the cretaceous bedrock area).

I’ve been told sharks teeth can be found there. I’d like to stop sometime and give it a whirl.
