This is the bivalve example I mentioned in another topic that my wife found and thought the attached shells resembled a heart.bivalve.png.bb6f48671bcc37d5629c3e526d55ab8c.png

A worm I believe to be Fossundecimafossundecemita.thumb.jpg.7d5f5cfe3989fa05925f98876fb11bfc.jpg

This is an example of the spoon worm Coprinoscolex.

Not sure that this is. Tooth.

Can  you post a few additional pictures?

Not a great fossil photographer but here are some attempts, and a view of the negative side.

I have to apologize for an over confident response.  I was just rubbed the wrong way at how some of the doubt was worded.

 

At best it's very poorly preserved.  I was looking at a "head" with mouth and eye, and potential "tail" or "fin" at the back.  The middle of the specimen not being preserved right, or the concretion not splitting right.  

 

This was from my first trip, and I used the "put your bucket outside all winter freeze thaw method"  this separated the halves of several nodules including this one, and I was never able to recover the other side of the concretion.  Never using that technique again.5e3071a79e876_possiblefishstructures2.thumb.jpg.0d6cb6391321b7262ac7a8a582469efc.jpg5e3071a8a3293_possiblefishstructures.thumb.jpg.82d9038f65d69a38fdd07f9759435869.jpg

I still see nothing that suggests fish, and I've seen a lot of Mazon vertebrates at this point.

Ok.  I'll edit the post.

This I believe is a Lingula with a full pedicle associated with a mazopherusa prinosi fan worm with its fan open.  Might be my imagination but I like to think this is an example of the two filter feeders competing for food particles.
