Is this a petoskey stone? I'm familiar with what they look like but this one is hard to tell. It could quite possibly be a petoskey with a smaller pattern, but I can't quite tell. And yes, it was found in northern lower Michigan. (Frankfort, Michigan)

Looks like fossil coral which is what Petoskey stones are made of.

 

But there are smaller chambers. I don't know if technically Petoskey stones have to be from Hexagonaria percarinata or if it is a generic name for bits of fossil coral from this area.

I also don't know enough about coral to say if a single species might have a large variation in chamber size.

Nice coral find!

Happy hunting,

I think it's a Charlevoix Stone rather than a Petosky Stone. Also a coral, also found in Michigan, also Devonian. But much rarer, and I think much cooler. Supposedly of the genus Favosites. Nice find!
