erose Posted August 23, 2012 Share Posted August 23, 2012 (edited) Here is something I found in the Glen Rose Formation of Texas. That's early Albian in age. It was found in a location collected by a number of us that produces good Leptosalenia texana echinoids. I find numerous "cidarid" spines at this location as well. So when I first saw this I thought it was just another Salenia but then noticed it didn't have the apical cap. But otherwise it looked complete so I kept it. (NOTE TO NEWBIES: always hang onto the things you can't figure out.) Last weekend JohnJ and I did a little collecting and then he came by the house and showed me how to use KOH. We used this specimen as the demonstration subject. It still needs more work but we were at least able to confirm that the apical opening is true and there is no sign of a broken cap. I have had one "expert" look at it briefly and tell me he knows of other un-described "Cidarids" from the GR. It is not like the known Phylocanthids. Any ideas what it might be?

JohnJ Posted August 24, 2012 Share Posted August 24, 2012 Erich, the more I look at it, the more I see a perfectly 'decapitated' Leptosalenia texana (Credner). Your find is certainly uncommon. It would be great to see some additional photos beside one of your better L. texana specimens. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
erose Posted August 24, 2012 Author Share Posted August 24, 2012 John, you are probably correct. I need to clean it up a bit more and get the best detail showing. Link to comment Share on other sites More sharing options...
