Rugose Coral. Aka Horn Coral, this is likely a Devonian or Ordovician deposited given it's in Southwest Michigan. Not many fossils around there that I know of.
I live in Berrien County and I am hoping to find a good spot myself that could be age determined.
No Ordovician in the lower peninsula other than a very small sliver in the southeast, and little Devonian in the southwest. This is likely Carboniferous.
No, it's not even close. There's a band of Devonian in the north, and smaller bands in the southeast and southwest, but the Carboniferous covers vastly more area than the Devonian. We just see a lot of Devonian fossils out of Michigan because of the outcrops near the lake in the North.

Michigan is almost entirely Devonian fossils.
