Odd fossil I found In Missouri

[Samurai]

Location is in Missouri

The area is dated to the Pennsylvanian 

most likely Raytown, Wyandotte Limestone

 

Found in limestone that was blasted out by construction workers

I have also found prehistoric fish teeth in the area (Mostly apart of Holocephali) along with Brachiopods, Crinoids, Nautiloids, horn corals, and unidentified cartilage from a limestone concretion.

 

 

 

 

I darkened the left image and lightened the right image to try and make it more visible or at least the darker details more visible

 

 

 

I did not bring measuring tools, here is the closet replacement for it that I could find.

It looks like bone from the texture and color. Note the solid exterior and spongy interior. Fish would be my first guess.

I thought it could be bone, but I am always skeptical considering how old the area is! if it is fossil bone it would be my first I have found!  I might try to mine around the limestone and use clear duct tape to hold it together!

I took the liberty of enlarging and brightening/contrasting some of your photos: 

 

 

 

 

 

This looks (to me) somewhat similar to some fin support bones from coelacanths.
