looks like some fossilized sea bed and fossils I find in southern WI and northern IL. The second to the last pic might be showing some corral.

I did see that coral type part, why I thought to add it. But the couple areas of large amounts of tight banding led me to the agate thing, even if it's not showing up well.

Well it may well be an agate, I don't think it is a fortification agate. We do find other type agate in MN like moss, water level. What that pattern reminds me of is fossilized lake bed or coral. I might have one I found here in IL in my truck which I will take a pic of, that is if I didn't give it away. Mary Ellen jasper is fossilized algae and some of it comes in a mat form which ther pattern not the stone reminds of what you have and has been formed in layers. We do have gray lakers from time to time and there is a pit in Carlton MN that is know for gray lakers.

Looks like many of my WI finds. Agree with the above on fossil material.
