Coralhead Posted March 14, 2014 Share Posted March 14, 2014 Can't figure it out. Looks similar to a primitive echinoid. Thanks in advance. Jim Link to post Share on other sites
Al Dente Posted March 14, 2014 Share Posted March 14, 2014 It's not an echinoid. I don't think it is a fossil. Link to post Share on other sites
Uncle Siphuncle Posted March 14, 2014 Share Posted March 14, 2014 i vote rock, not echinoid. primitive echs still have distinct plate detail. Link to post Share on other sites
fossilized6s Posted March 14, 2014 Share Posted March 14, 2014 1. Its almost perfectly symmetrical, almost like an artifact. 2. Concretion? The cracks look like a concretion. Link to post Share on other sites
Coralhead Posted March 14, 2014 Author Share Posted March 14, 2014 (edited) Wow. Thanks for the inputs. Surprises me that you guys think it may not be a fossil. What is a concretion ? I agree about the plate detail Dan. It should have some echinoidal patterns. Edited March 14, 2014 by Coralhead Link to post Share on other sites
