Unrecognized fossil from Middle Devonian

Hello all. 

Found this oddity in a small piece of shale, adjacent to the northern branch of Smoke Creek. 

I believe this is Windom Shale, Hamilton Group, Middle Devonian.

It reminds me of something, but I can't place it. 

Any ideas are welcome. 

Pelecypod was my first impression, but ... ? 

 

EDIT: to add size. 

6 mm in length.

A hem . . . We usually advise folks to include something for scale. :)

Following on this one. The outline says bivalve to me, but the patterns look like trilobite. If you rotate the bottom picture, it looks like half a pydigium, but it doesn't match anything in my books.

Perhaps a piece of some sort of spiny Brachiopods

Brachiopods don't generally mix textures like that. COuld be two different animals superimposed, though.

Is that an ostracod? No wonder it had me stumped.
