Not taking a side here. Just wondering. Any chance this pattern is primitive enough to be a homologous to it ?

before my batteries on my camera died heres a couple more......there also seems to be some form of some lines inside the one hole that may indicate something to someone

Could the second picture show the clams shell?

I'm definitely going with wood. And I have found a couple with that ridged pattern inside the borings that yours has. I'm not sure how that would preserve but it sure looks like the pattern on the clams that bore mechanically.

well I sure missed that in the hole!     if carl has seen the borers preserved in their hole like that, it's gotta be wood.  Wood was always the most obvious answer to me,  but I just couldn't get past these close up pics of the texture.  sure looks like bone to me.    But  i ignored the rest, as a result.  moral is dont zoom in too much if you don't have the best pictures to begin with!

It looks like a fragment of a shell from a brachiopod.  If it is, then the hole might be a mold.

Bones get bored by clams also.

The similarity in texture to that of the rest of piece sort of rules out shell.

Could the missing surface of a trace be explained by a slight case of pyrite disease ?

I see what you mean.  Carl's comment may have nailed it.  If Brad, with the fossil in hand, sees the design as an impression rather than a fragment, then that provides further support.

to me in hand looks like impression not fragment

I agree that in this case it looks more like an impression: I have a similar specimen. But I also have one from ?Ramanessin that has that same pattern but it is preserved as a thin black sheet lining the boring. I have no good explanation for how either forms.
