hobbitfeet Posted October 7, 2017 Share Posted October 7, 2017 Hi guys. Thanks to everyone who helped me with my last IDs. I have some more that I'm stumped about from the same area in Eastern Missouri. This first one looks like the echinoids I found in the Cretaceous in Texas. It's about the same size and shape with the same very small spines or tubercles on it. This other one resembles the possible echinoid but is a flat plate with the same small bumps.

hobbitfeet Posted October 7, 2017 Author Share Posted October 7, 2017 I think this one is Receptaculites but I'm not sure. Link to comment Share on other sites More sharing options...
ynot Posted October 7, 2017 Share Posted October 7, 2017 Sorry I can not help with id, but it would help improve Your pictures if You set the object on a solid surface rather than holding it in hand.

hobbitfeet Posted October 7, 2017 Author Share Posted October 7, 2017 I'm not looking for genus and species. I want to know if it's possible. I never heard of a sea urchin being in rock this old and I want to know if sunflower coral is known in this region of Missouri near House Springs.

Kane Posted October 7, 2017 Share Posted October 7, 2017 From what I understand, Receptaculites went extinct sometime during the Permian. If your area has a lot of Cretaceous material, and this is a Receptaculites, I wonder if it could be an erratic. There may also be some Ordovician exposures there or nearby of the Kimmswick Formation (which usually outcrops in SE Missouri, but some have been found near House Springs). ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
