Back with...brachiopods Id please?

[Recker]

Sorry guys I'm back with more Brachiopods.  Usually the ones I find are embedded in matrix but these are nice ones, found near the Whitewater River.  I've been going thru my ID book and wonder if my stab at identification is right or wrong, I learn either way.  Once again thanks again for your help!

 

Using the fourth photo with the shells right side up and with a ruler.  Top left and middle are they Rafinesquina?  Top right is that Holtedahlina?  Bottom left Platystrophia?  Bottom right Plaesiomys?

The big ones appear to be Rafinesquina ponderosa.  The one with the strong plications appears to be Platystrophia / Vinlandostrophia sp.  The third one is probably Plaesiomys subquadratus.  Glyptorthis insculpta is similar in general shape but has prominent growth lines perpendicular to the ribs.  I can't see any from the photo.
