Hipockets Posted November 12, 2019 Posted November 12, 2019 Hello Everyone, I need some help identifying what i have here. I have several pieces of matrix with a shell valve attached. All the pieces are less than 6 inches. They all have sort of a wavy-ness to them. Some seem to be part of a cluster ( 2 or 3 attached at the base) . These are maastrichtian from the Peedee formation in SE North Carolina. Thanks for your help.

Hipockets Posted November 13, 2019 Author Posted November 13, 2019 Dryptosaur, have you any idea which sp. ? I really don't know how common it is in the Peedee formation, I don't recall seeing it at other locations.
Plax Posted November 13, 2019 Posted November 13, 2019 Am still thinking this might be Spondylus gregalis (which I had mistakenly called congregata). the missing ears might be a preservation thing as it would be if this were a Pteria. I don't believe the latter grow in clusters though. A good molluscan mystery and am pretty sure one of the Gulf Coast Cretaceous researchers will know this shell. They have better preservation there more like the Peedee site where you found this. Odd that we haven't seen it in any of the quarries around here or river bank exposures. Either not common or not usually preserved enough to be recognized. 1
Al Dente Posted November 13, 2019 Posted November 13, 2019 Here's a Peedee Spondylus. I don't know the species, it fell apart when I picked it up. 2
Hipockets Posted November 13, 2019 Author Posted November 13, 2019 I have pieces of both sides of a valve and there doesn't look like there was ever thorns on spines, but I guess that could be a preservation thing also.
MikeR Posted November 13, 2019 Posted November 13, 2019 Is Upper Goose Creek Limestone exposed at your site as well? Looks like Nodipecten and N. peedeensis (Tuomey & Holmes, 1855) is found within the GCL. 1 "A problem solved is a problem caused"--Karl Pilkington "I was dead for millions of years before I was born and it never inconvenienced me a bit." -- Mark Twain
Plax Posted November 13, 2019 Posted November 13, 2019 These shells are contorted and attached in clumps in oyster-like fashion. I can see the ribbing looking like Nodipectin though. You know better than I Mike!

Hipockets Posted November 13, 2019 Author Posted November 13, 2019 Thanks everyone for the comments, but I am going to try a few different pictures. I think maybe some of my original pics may be misleading. I just dont see these being pectens, but this is why I asked. Can pectens grow in clusters ? Also there is no Goose Creek material at this site. These seem to grow or morph in all shapes , not just pecten shaped. Thanks again.
Plax Posted November 14, 2019 Posted November 14, 2019 Great pics! Plenty of diagnostic features here I hope. Wish I could help...
fifbrindacier Posted November 14, 2019 Posted November 14, 2019 Great pics ! You're right, those aren't pectens, but not spondylus either. They more look like gryphae oysters.

fifbrindacier Posted November 14, 2019 Posted November 14, 2019 You can also have a look at this site : http://www.fossilshells.nl 1 "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

Hipockets Posted November 15, 2019 Author Posted November 15, 2019 Good news. Ralph Johnson , from New Jersey , well respected and knowledgeable looked at the pictures and said they are definitely Spondylid, and 90% sure they are Spondylus gregalis. Thanks everyone for the feed back. 1
fifbrindacier Posted November 15, 2019 Posted November 15, 2019 Wow, i've never seen spondylids like that, very nice ! "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."
