Unknown fossil

[TMiller19]

I am new to the forum, so I hope I am doing this correctly. If more information or pictures are required please let me know.

I found this fossil at the Penn Dixie site in Hamburg, New York, on the north end of the site.

I have not been able to find anyone who can tell me what this may be.

Thank you for any help you can give me.

Maybe an enrolled trilobite, looking at the head and tail?  Guess at best.

It is a "Squish-Out".  

 

These are the remains of sea creatures that have been filled with mud, and were then crushed, allowing the mud to escape and form around the item. 

They are found throughout the Hamilton Group. 

They can be made from any shelled creature - I have found some made of pelecypods, gastropods, and brachiopods. 

Sometimes the shelled creature cannot be determined. 

Yours looks like some sort of bivalve, possibly.

I've heard a number of arguments for what those forms are. Some say that are Trilobite resting or feeding traces, some say they are relicts of the sediment compression, others that they are from pelecypod burrows. I know that all of them that I've seen are bilaterally symmetrical and kind of look like a coffee bean, as yours do, but sometimes have one end that is longer than the other.

I would like to thank everyone for the help and information.
