Kalkberg formation Proetid?

[Misha]

Hello everyone!

I have been recently going over some of the matrix I collected over the summer, more specifically, stuff from the Lower Devonian Kalkberg Formation in NY.

I have found many nice new brachiopods which is what I was looking for, like a fairly nice preserved Leptaena which I was really excited about as I didn't get any initially and they are really beautiful.

While cleaning out that brachiopod this fossil also popped out of the rock, I saw its cross-section and initially didn't think much of it but when I got it in hand it appeared to be a trilobite cephalon, it is tiny and unfortunately due to the nature of this matrix as I was trying to save it parts crumbled away.

I am now left with what you see in the pictures, to me, it looks like a proetid cephalon but I have no knowledge of whether this group is present in this formation and what it could be.

Any help in identification would be greatly appreciated, 

Thank you.

Not sure what your mystery object is, mate, but I'm very glad you found some nice brachs. 

Leptaena is one of my favourite genera.

I agree, strophomenids in general are probably some of my favorite brachiopods while Leptaena is one I find especially interesting and beautiful

Maybe @Kane or @piranha would know?

Sorry man, your photos are a bit blurry.

Yes, I apologise about that. It is really small and hard to photograph. This is the best I have been able to do so far with my digital microscope

A bit fragmentary to make out, but it could be Burtonops or Viaphacops.

What would point to this?

To me what is left of the eye and the glabella they look a lot like a Proetid

The picture is not ideal, but I think I see some granular texture.

I'll try to take some more pictures with my phone or a macro lens on my camera when I get the chance

[Misha]

Here are some additional pictures I was able to get with my phone,

It does appear to have some granularity to it's surface.

I'm still not sure what this object is.

Would any additional pictures be helpful?

Wow! Very interesting, thank you for the help.

I will have to look into this
