I need an ID for this clam. I found this clam in a concretion. it was taken from the Kevin member of the Marias formation. Th Kevin member is listed as Santonian Cretaceous. The location is 5 miles west of Loma Montana.

Looks like a Inoceramid of some kind, hopefully someone will know the formation. 

Nice colour.:)

Tidgy's Dad, I have a few Inoceramid clams. While Inoceramus bivalves should be found in the Kevin member I have not seen them.  I have a few younger specimens collected from Glendive. See phot of Inoceramus clams.

 

  This specimen I need ID doesn't have the luster or growth rings inceramus. The unknown specimen is also much more angular. 

 

 

 

These photos are of Inoceramus bivalves I collect near Glendive Montana.

Andreas thank you for your help. I don't believe the shell in question is a Aptychus. The shell has the characteristics of a clam.
