Looks like a nice little (although somewhat crushed) orthoconic nautiloid.

That cephalopod sure stands out against the black matrix!!!!! Nice find. Out of curiosity, how did the name @bluegilldvm come to be? A veterinarian that likes to fish?

@minnbuckeye - I’m veterinarian that studied fish medicine. Grew up catching mainly bluegills, so they are my favorite fish. Unfortunately I don’t fish too much anymore. Too much time working and looking for fossils. 
 

@ClearLake- Thanks for the ID!!!!

Well then, you must be a distant cousin and not my twin!!

 Actually, the last 2 years of my veterinary career, in addition to maintaining my practice, I became the veterinarian for the Minnesota State Trout Hatcheries. ALL  my knowledge of fish medicine was learned from this experience. Hopefully we will continue to see your finds!

Isorthoceras is Ordovician.  Pseudorthoceras is found in the Carboniferous.

Yes, I know. Though I think Pseudorthoceras is Permian as well.

I just don't know of the species Pseudorthoceras socialis and am interested in knowing more. 

I wondered if he's mixed up a couple of species. 

Like i do, as you know!

And there are also records of Pseudorthoceras from the Devonian, but it is primarily found in the Carboniferous.

 

The OP mentioned that Listracanthus is found in the same area so logically we can exclude an Ordovician taxon.

Magnificent find. I freely admit I just spit coffee all over my keyboard when I saw the pictures.

 

This link might help us narrow down the identification if you happen to know the formation this shale is from. (USGS Grundy County Geologic Units)

I am happy to agree. 

All I am asking for is info on the species Pseudorthoceras socialis as it is a new one for me. 

Can you help?

I don't spend a lot of time on cephalopods, but at first glance it does not appear to be a valid name combination.

Thanks. :)

Which is why I was suggesting maybe @RCFossils had mixed up a couple of names.

Like I do with Flexicalymene. :DOH:
