Shell and strange design

[Brian James Maguire]

Hi guys curious abut shell id and also the net like main patern, hope you can shed some light

The netted pattern is highly suggestive of a fenestrate bryozoan.

@Kane thank you for that, would i be right in saying that to the top of the shell is that smaller pattern also bryozoan?

Yes, that one is a Fenestella sp.  and the larger one is another fenestellid.

I agree.

Fenestella amd another fenestrid.

The brachiopod would appear to be an athyrid, maybe Composita sp.

Thank you on the shell id i was thinking it was some type of clam with the two ridged shell like the one in the photo bellow, i still have much to learn with shells

Bivalves do occur in the Early Carboniferous Limestones but they are much more uncommon than brachiopods and often broken.

The lines of symmetry are generally different too.
