Not sure what these Crushing tooth plates belong to (Solved: Fragments from Metacoceras Sp.)

[Samurai]

 

Location: Missouri

Timer period: Paleozoic (Might be Pennsylvanian)

Formation: N/A

 

Hello! My friend recently gifted to me a few fossils and he brought to me an interesting tooth/crushing plate and asked if I was familiar with it, and unfortunately I was not!

 

He mentioned what he thought it could belong to, but I am unable to recall what species.

 

Some information I was told was that his mother actually found his specimen at a location a few years ago and I was unable to get a picture of the location or check it out due to a busy schedule! 

 

My friend's specimen (he took home):

 

Around 5-6 cm

 

 

The one he gifted me:

 (backside)

Roughly 2.5cm long ( The plate fossil itself)

I don't think these are teeth.  They look more like fragments of a coiled nautilod or ammonoid.

Very well could be! Would you by chance know what species they would be derived from? Or is it not recognizable

I think you are 100% correct from what I can tell and all the information makes sense
