    This small cluster is in excellent condition. Many of the spines of this oyster are still present, normally these are broken or worn off. It is often found in very large clusters. It was found in the basal sands of the PeeDee Formation at a quarry in Southeastern North Carolina. These oysters are often found in association with Hardouinia mortonis and kellumi echinoids.

     

    There has been some discussion (see comments) among knowledgeable persons of the PeeDee and bivalves in general that the I.D. that I have from my source could be incorrect. I feel I must make all who view this aware of the possibility. My published resource for I.D. is "Volume 2 North Carolina Fossil Club; FOSSIL MOLLUSKS page 56. Richard Chandler, Editor"

    I have some clean lower valves if you want to take a pic of them Six. They look like they came from a completely different mollusk. Sort of like a modern Crassostrea virginica. These are in the NCFC book as the taxon you list them as but suspect they are different growth habit  morphs of Flemingostrea subspatulata. This would be a good subject for an oyster researcher if there are any???

    Oh; and amen the brews!

    I agree with Plax.  The frills on the Pee Dee F. subspatulata weather distinctively more so than examples that I have from Georgia and Alabama.  I have Graphaostrea vomer from Alabama and Mississippi and they are not nearly as large. I'll post some pics of them shortly.

    Ok guys, after reading your comments and looking at the link you posted Plax, I am seeing your points on this. Plax, especially the very last photo in your link. That oyster is without a doubt F. subspatulata, but it does have the same "spines". Mike, I would love to see your photos. May have to edit the Genus and species on this one. This would not be the first time an ID was shown to be incorrect in the NCFC books. But overall they are fantastic resources.

    I'd leave the ID as is Six. You have correctly identified your specimen to a published source. It would be good to have a couple of pics from Mike R. of an actual Gryphaeostrea vomer added to this string of information as he suggested. This way if someone is searching the name they will be able to see the progression and logic of your research. This is as valuable as the posting of a pic with the name.

      I agree that the NCFC books are fantastic! Can't wait for the final volume(s) to be published.

    I think you are correct, at least at this point in time Plax. I think what I will do is add a comment in the more info section about where the I.D. came from and the possibility of the I.D. being incorrect.
