Rockwood Posted October 5, 2017 Share Posted October 5, 2017 I think this is basically a Mucrospirifer mold but what else is there ? Primarily the rugose feature. Pedicle attachment ? Link to comment Share on other sites More sharing options...
ynot Posted October 5, 2017 Share Posted October 5, 2017 Can not remember what they are called, but I think it is the interior supporting structure of the brachiopod. First 2 pictures, do not know what 3 is. 1 Link to comment Share on other sites More sharing options...

It's the same thing at a different angle. That becomes problematic when you consider what I've been calling a sponge boring toward the top. It would almost have to be within the dissolved shell body space. Making this simply an internal mold. Wouldn't it ? Most of the horn corals from the quarry are full of what ever the trace is.

TqB Posted October 6, 2017 Share Posted October 6, 2017 Lophophore is the soft part, the spiral supporting structure is the brachidium. Not sure what you've got there though... 1 Tarquin Link to comment Share on other sites More sharing options...

Not sure what you've got there though... Both thoughts have been troubling me. I should have included Tony's response. I think you have clarified where we were trying to get to. Just how such a structure would end up looking this way in the mold I didn't make much progress with though. I assumed it was a deficiency on my part.
