Dear USA Brachiopoda enthusiasts,

Could you see these images please? What is your expert idea about ID? 
I know that could be difficult from images. Thank you for any help you can offer.

For the last one, Rafinesquina ponderosa perhaps?

It is smaller and has less ribs...

Thank you very much for your help, Utahfossilhunter.

The first one it may be Cincinnetina sp.

I was reading some paper about that genus also. Thank you very much for your help.

They all are almost certainly Cincinnetina sp. One of two possible species but formation info needed to better ID to that level.

The second one is likely Plaesiomys subquadratus

 

Agree on the first one:  Cincinnetina.
