Hey guys. I’ve got this bivalve that needs a labeling. I collected it from the Jurassic age Twin Creeks Formation on the east side of Salt Lake City. It has some shell material left but most of it is an internal mold.

I’ve found this paper but I don’t speak “bivalve”-ese so I need a translator.

Can you see some ear fragment? 

 

That shell texture resembles some Plagiostoma sp.
