Tiny Fossil

[jnicholes]

Hello,

 

I was organizing my fossils I got in Kemmerer, Wyoming, today. I stopped to look at a small Phareodus fossil I had. I noticed something I never noticed before. I took the fossil and put the odd thing I noticed under a magnifier. Picture it attached.

 

I am not going to lie, it is TINY. It has ridges one one side as well as 7 lines coming from the dark part. Any idea what it is? Could it be a plant, or part of a fish?

Can't tell, picture quality not the best...

I was actually in the process of getting another photo. Here it is.

I apologize about the picture quality, by the way.

The black and white shows the detail so much better.

To me it looks like a fish fin possibly pectoral or pelvic

Thank you for the input so far. Just one question. I thought it was a fin too, but do fins have a rigid side like that?

Thank you so much for the help guys. I appreciate it. I think @Fossildude19 is correct. Thanks so much for the help!
