Paleo shark teeth?

[cboll11]

These were found in a coal mine in southern Illinois. Can anybody identify if they are shark teeth and, if so, what species? Specifically, these were found in the Herrin #6 coal seam. Any info would be great appreciated. The first two pics are of the same specimen and the third pic is a different specimen. I find many Edestus and petalodus teeth, but these are the only teeth like this I have spotted.

Welcome to the Forum.

 

Nice fossils ! They do look like paleozoic shark teeth to me.

Can't help with ID, but some other members can.

Campodus?  

[JimB88]

Agassizodus for the first two me thinks. Possibly Orodus for the last.

Are Agassizodus and Orodus commonly found in Illinois? Just by the pictures, can you tell me if these are in decent condition? Thanks for your help!

They look good, but would benefit from some preparation. Not sure how common they are, but they can be found there.

These all appear to be Campodus sp. teeth in my opinion. Great examples too!

Edit: also, as pertaining to you're question, as Paleozoic shark teeth go, they are one of the more common ones. Campodus as a genus is one of the only Carboniferous genera that we have nearly complete jaws from. But yes, Paleozoic shark teeth in general are rare, especially when compared to shark teeth from the Mesozoic and onwards. They also appear to be complete, but as stated above, they could use some preparation by someone who has some expertise in it. These teeth tend to have cracks that you can't see until it is too late. I recommend an air abrader with baking soda since you are working on a relatively soft material.

Beautiful teeth they look like they will prep up really nice I agree with a Campodus sp. for both of them,
