New Castle VA Devonian Ostracod?

[fossil_lover_2277]

Hi all, I collected this fossil a while back, I’m wondering, is it an example of a large ostracod? The fossil is from the Devonian Chemung/Foreknobs formation near New Castle, VA. I have no idea what it is, but ostracods are known from the area, and I could see them as a possibility. Any ideas?

 

*fossil is 3cm in length

Very interesting @fossil_lover_2277... I don't think that it is an ostracod, it is too large and it doesn't present the same features as I would expect. Maybe some some sort of bivalve, or a damaged plant fossil. My other thought is mineral staining, though I think that this is less likely. I'll be interested to hear what others have to say on this.

My first reaction was phyllocarid.

Trilobite cephalon, with part of the axial pleural exposed.
