✅ SOLVED crazy rock I found in our woods

[rockcrazy]

I found this rock in our woods in southwest Michigan. We live across the street from a lake so im assuming it is some sort of fossil. I've found other fossils but they have looked nothing like this. Any help is appreciated.
Thanks

That sure is wild looking. Maybe a Brain Coral fossil

I thought it looked like some sort of coral but we are far from an ocean. Thanks for your reply

I thought it also looked like some sort of coral but we are far from an ocean. Are there sorts of coral in fresh water lakes? Thanks for your reply.

Look back in time. Before glaciers shuffled the deck.....a sea once cover the state.
The great lakes them selves have been changed repeatedly over time.

Wonder if it is some kind of Salt you have Salt mines up that way.

No...there are no salt mines near here

The Himalayas have sea-shell fossils at the tops. The World has shifted much in the last 350,000,000 years (coral was VERY common in the Devonian Period).

In the Devonian most of Michigian was under a salt-water bay.

Michigan was part of the ocean.. Petoskey stones are fossilized coral and they are found here in Mi as well as are other sea fossils.

It's so exciting to possibly have a rock that may be that old. I'll be keeping my eyes to the ground every time I walking through the woods.
thank you's for your help

River gravels turn up small pieces of fossils/corals in Mi..inch or two and been tumbled ,broken up. Yours is a great piece from somewhere..

I find similar fossils often on the beaches of Lake Michigan ( Illinois side). It's always so much fun.

They are called Halysites .
A member here helped me out last year with the identification.

No...there are no salt mines near here

they are hard to spot, but there is an estimated 71 trillion tons beneath your feet.
