This is the brachidium of a spiriferid brachiopod, the internal structure that supports the lophophore. 

Very nice specimen

@westcoast the internal preservation of brachiopods on the Malahide formation is excellent but unfortunately the external preservation is very poor making it difficult for id

Ah spriferid ! I thought it might be composita for some reason 

It could be something like Composita - I don't know how you could distinguish spiriferid and athyrid easily based just on the brachidia?

Ah Yes, I agree, i didnt read the first post fully, so i should have said 'possibly spiriferid,' but of course athyrid is much more likely given they are present in abundance.

@TqB @westcoast i did a bit more digging and it probably is an athyrid ,the most common athyrid by far on the malahide formation is glabristria , but this one looks so different i thought it might be something else altogether
