Tiny Devonian shells

[DNF]

Hey all, I haven't found my trilobite source yet, but I did find this neat hashplate.

 

It comes from a creek in White Sulphur Springs, WV and is probably Devonian.

 

I haven't seen shells this small before. I'm guessing they're brachiopods, but otherwise I have no idea what they might be.

 

I couldn't get a clear picture with a scale included, but the largest shell is a little under 1/4". This photo is the closest I can get to the piece and still be in focus.

 

Any ideas? Thanks

I took the liberty of turning the image sideways, to get a bigger picture.

This PDF may be helpful with narrowing down the possibilities. 

 

Maybe @Shamalama will be able to narrow it down for you.

The genus Zygospira is a tiny brachiopod that is found in dense clusters like this in Ordovician age. Not saying it is Zygospira, but possibly something closely related.

You need to get picky with all the tiny details to sort this out. A lot of the individual specimens are distorted or broken, but with this many samples you should be able to get a good description by looking at details from many of them.

Thank you all . I think chonetes is a good match for a lot of them. I'm going to do some research and see if I can narrow it down to species.
