Al Dente Posted January 31, 2012 Share Posted January 31, 2012 This is most likely Phymotaxis tournoueri, the regular echinoid from the Peedee Formation. Link to comment Share on other sites More sharing options...
Plax Posted January 31, 2012 Share Posted January 31, 2012 thanks for the corrected spelling Al! Was shooting from the hip yesterday without seeing the pics. Nice raft of Flemingostrea Mark. That oyster was described from an exposure on the NE Cape Fear River (or just upstream on a small trib) in our county. You can get some nice singles under Croome's Bridge at low water.

Plax Posted January 31, 2012 Share Posted January 31, 2012 If you have extra you might offer one to Trish Weaver at NCSM. Link to comment Share on other sites More sharing options...
Indy Posted January 31, 2012 Share Posted January 31, 2012 Not being an echinoid Aficionado...I'm wondering how rare is this find? I don't remember ever seeing an echinoid with intact spines in the upright position.

Interpaleo Posted January 31, 2012 Share Posted January 31, 2012 Really cool find, Looks like its gonna be one nice specimen all cleaned up! Link to comment Share on other sites More sharing options...
Plax Posted January 31, 2012 Share Posted January 31, 2012 Indy, rare but not unknown in the loose arenite of the Rocky Point Member of the late Cretaceous Peedee formation. Wish I could cite the paper in Southeastern Geology but do my internet from work away from the lit. Will try to add it to this thread later.

Indy Posted February 1, 2012 Share Posted February 1, 2012 Mark What process or technique are using to prepare this fossil? Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
Hipockets Posted February 2, 2012 Author Share Posted February 2, 2012 Indy, I am open to suggestions. All I did so far was a vinegar soak, then baking soda/ water soak to neutralize, they have since been soaking in water and I pick away a little bit each day trying not to get to aggresive.I dont think air tools or acids are worth the risk ?Any ideas? Thanks. Link to comment Share on other sites More sharing options...

Thanks. Asking for suggestions how to prep a fossil opens a can of worms. This is YOUR fossil and I'm not going to suggest how YOU should or should not prepare it. One thing I will say...A discussion on this subject would be a good idea if your not comfortable with continued preparation Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...

Hipockets Posted February 2, 2012 Author Share Posted February 2, 2012 Everyone, please flood me with advice, what and how would you go about cleaning and preserving this ,if it was yours. Or would you leave it as is? Link to comment Share on other sites More sharing options...
Bill Posted February 2, 2012 Share Posted February 2, 2012 One thing I wouldn't do is use ANY acid. Echinoid tests and spines are calcium carbonate. Easily dissolved in acid. KOF, Bill.

Nandomas Posted February 2, 2012 Share Posted February 2, 2012 One drop of WC acid followed by running water works with other echies from the same formation/mine, but in this case you risk to separate spines from echinoid. Try to work with a gentle brush Here Diana's half spiny echinoid from Castle Hayne, I don't understand why she doesn't even let me touch the specimen :ninja: Erosion... will be my epitaph! http://www.paleonature.org/ https://fossilnews.org/ Link to comment Share on other sites More sharing options...
Bill Posted February 2, 2012 Share Posted February 2, 2012 I agree Nando, but that's a little different to soaking it in vinegar. Very nice specimen Diana. KOF, Bill. Welcome to the forum, all new members www.ukfossils check it out. Link to comment Share on other sites More sharing options...
Indy Posted February 2, 2012 Share Posted February 2, 2012 I'm sure you probably have found broken pieces of echinoids in matrix from this locality. Those pieces would be the ones that I would experiment with before attempting to prepare your "pride and joy".

Wrangellian Posted February 2, 2012 Share Posted February 2, 2012 Interesting specimens.. I don't know how loosely consolidated the matrix is, it appears loose and sandy - If it's loose enough, then probably just a needle/pin might work, though it would take time. Sometimes there are no quick and easy solutions, and the best thing is lots of time and patience and a steady hand. Ever played 'Operation'?
