I posted this find in my trip report thread http://www.thefossilforum.com/index.php?/topic/95184-51319-oglesby-il-roadcut-pennsylvanian-shark-bits-brachiopods-and-more/ but I thought  I would put it here too to get some more eyes on it. This piece is from the Pennsylvanian LaSalle Limestone member of the Bond Formation, collected on 5/13 and prepped some over the weekend.

 

At first I thought it was the root of a shark tooth, but as I prepped and revealed the multiple "teeth" on top and the ratio of root to teeth it did not match up. That makes me think it is possibly a part of a jaw with teeth in it, but I have never found anything like that at this site before, nor have I seen any reported from this formation. Any ideas? The scale below is in CM.

What a cool looking find!

Looks like a fish premaxilla to me.

Thank you! That is really helpful in putting it into context.
