i recently got a maintenance job at a local golf course and found some fossils in the soil, and at least one of them it a cephalopod. here are a few of them now:

1. 2.

3. 4.

LOL, what a great job for you! This should be interesting.

Nice fossils! And one does indeed seem to be a cephalopod.

Find more.

Let's see how I do...

1. Apertural end of a Horn Coral?
2. Worn Tabulate Coral?
3. Don't know, maybe burrows of some sort?
4. Possible ceph, could we see a view of the broken end?

all i know for sure about 1 and 2 is that they are both rugose. they resemble Heliophyllum and Eridiophyllum from the Devonian, but i cant tell what period theyre from. 3 might be a Mississippian rugose coral. im pretty sure 4 is the Mississippian nautiloid Mooreoceras. one of the papers ive read lists about 9 species in Michigan (along with over a dozen other ammonoid and nautiloid genera).
