Have any of you folk found or have a picture of this species? Am trying to find out what "crassostrea" is found in the Peedee exposed on the Cape Fear River as cited in Sohl & Owens 1990.
I found these nice oysters yesterday at Lake Travis, Cretaceous aged Lower Glen Rose Formation Kgr(l), Trinity Group, Travis County, Texas.
