Hello. I got this fossil at a store and I forgot the name of the bivalve. Thank you!

It looks like an oyster. Possibly Graphaea sp.

I'll take a shot at it for you, it appears you may have a specimen of ostrea bryani.Although it is just hard to tell with no scale present. That type should be a small shell. Also, that would be assuming a late Cretaceous time period you recovered it from....

The source the photos come from here is about 100 yr old, so I presume that name is still in use???

If not that, could it be ostrea monmouthensis? My main study isn't in shells, but when I saw your pictures it reminded me of a shell specimen I'd recovered from the Coon Creek Formation previously. If per say, it turns out to be one of these, do you live around me???

Cool. That name sounds familiar. Thank you!

Pretty sure it's not a gryphaea. This shell is more circular. Thanks for your help though!
