Fossil Or Rock?

[Bev]

Found this along a river. Probably Ordovician, could be Silurian or even Devonian. SE MN.

Looks like it could harbor a fossil. Or maybe it is just a rock!

What do you think?

Thanks for looking!

I can´t really see from the image, however, there is a central structure in the rock that looks different. Could be something. Good luck in getting an id.

I don't see any obvious fossils here.

Some might say the bumps on this rock

could represent this or that ... However, speculations

is a far cry from identification.

If ya stare at some rocks ... long enough

you'll see Elvis.

Thanks! You are right, it is the pieces in the middle Here is another pic that might help.

Here is another image of it. Yes, it is the "bumps" in the middle that I'm thinking may be a worn fossil. Or, I just have a very good imagination! Which I do! LOL :-D

But I figure it doesn't hurt to ask.
