KimTexan Posted August 17, 2018 Share Posted August 17, 2018 Echinoid urchin spine is a complete guess. I don’t have a clue. Does anyone know what the tan thing with bumps is? It is just over 2 cm long so far. I found it in the Cretaceous, Grayson Formation in North Texas. It has Mariella brazoensis, Waconela wacoensis, a little nautilus, way too many oysters among other things in the conglomerate with it. Could it be an urchin spine? It has tiny, basically microscopic bumps all over it too. It still needs work uncovering. I came to the oyster on top of it and will have to take another approach to removing the oyster.

ynot Posted August 17, 2018 Share Posted August 17, 2018 That is what I was thinking. crab leg. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

BobWill Posted August 17, 2018 Share Posted August 17, 2018 Agree, and is that a scaphopod on top left? Link to comment Share on other sites More sharing options...
JohnJ Posted August 17, 2018 Share Posted August 17, 2018 Looks like an echinoid spine fragment at the top left of the crustacean leg. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Coco Posted August 17, 2018 Share Posted August 17, 2018 OK with John : could be a part of a sea urchin spine on the left side.

GeschWhat Posted August 17, 2018 Share Posted August 17, 2018 Aren't there some sponges that are bumpy like that? Perhaps it is too smooth for a sponge. Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...

Yes, I believe that is a fragment of an echinoid spine on the left. This conglomerate is full of all kinds of stuff. There is this thing in the conglomerate. It’s got oysters all around it. So it needs more work to get it out. I’m thinking it is a horn from a Graysonites ammonite, but not sure yet. If so only a fragment of it is present. The conglomerate split in two. Before it did I had not noticed it. This is the back side of the same half. The other half all you see is gray mud looking matrix. This is the horn from the side. It would be a pretty thin horn if it were from a Graysonites, so I’m wondering if it is something else. I have found 2 Graysonites in the same area, but their horns don’t really match this. Maybe it’s another species. Any thoughts as to what it could be? Link to comment Share on other sites More sharing options...
BobWill Posted August 17, 2018 Share Posted August 17, 2018 Dipoloceras can have horns like that but I believe they are only in the Goodland and Comanche Peak Formations and pretty rare. Link to comment Share on other sites More sharing options...

So, do you have any ideas as to what it could be? I tend to think it is an ammonite fragment with a horn on it, but it could be something else. This is kind of funny, but when I first saw it I thought starfish. I’d been looking at places to hunt in the Ordovician and Silurian of Oklahoma and found a couple places that had starfish on the menu. I will keep working on this conglomerate for a while longer. I’ll try to expose it. I’m sure I’ll discover other things too. Link to comment Share on other sites More sharing options...
