Not a crionoid!! Fish part?

This was discovered while hunting in the Burlington Limestone in no other than Burlington, Ia. If anyone has hunted this formation, they would know 90% of the rock is made up of light colored crinoidal debris. Occasionally a brachiopod s encountered and they may be darker than the crinoids, but pale against this. I know there is a fish layer in the Burlington and am hoping that this may be the ID.

Can we have a scale, please.? 

And a close up of the 'pores' ?

It looks like a bryozoan to me, but strange shape.

Definitely a chondrichthyan, might not be Deltodus though. My first impression was Chomatodus or Sandalodus. Regardless, holocephalan.
