marcltetreault Posted July 19, 2022 Share Posted July 19, 2022 I’ll try one more tonight while I have the attention of so many helpful people. this was collected also at Colt’s Neck, New Jersey. From a riverbed Link to comment Share on other sites More sharing options...
Rockwood Posted July 19, 2022 Share Posted July 19, 2022 I can imagine the minerals of a belemnite guard degrading to this point. ' can't really identify it as such though. Link to comment Share on other sites More sharing options...
marcltetreault Posted July 19, 2022 Author Share Posted July 19, 2022 I agree with you on that. I have many belemnite guards and none look at all like that, color, shape or deterioration. My guess and here is my very Non-Expert opinion is that it is a tooth of some sort. It is shaped and profiled as some I have seen. It has what I think is a root running though it. Then again it could be a rock with my imagination running wild. Link to comment Share on other sites More sharing options...
Fossildude19 Posted July 19, 2022 Share Posted July 19, 2022 I don't think it is a tooth. No enamel present. My first thought was very worn/split belemnite guard. The crystaline structure is a sign against it being a tooth as well, and more consistent with a calcitic belemnite guard. (Although I could be wrong, and it could be quartz rather than calcite. ) Try putting a bit of vinegar on it - if it fizzes, it is calcite.

IsaacTheFossilMan Posted July 19, 2022 Share Posted July 19, 2022 The folding of the (possibly) calcite (could also be some silica based one, like quartz?) - yeah, let's just call it crystal right now... The folding of the crystal seems inconsistent with belemnites, as on this one it goes through the whole specimen. From the wonderful work of Hoffmann, René & Stevens, Kevin. (2020). "The palaeobiology of belemnites – foundation for the interpretation of rostrum geochemistry." Biological Reviews. 95. 94-123. 10.1111/brv.12557 Looking past the atypical morphology of the cross-section, which could be explained at a stretch by compression, I have never seen folding (doppellinien) like this one, and cannot make out any distinctive features of a belemnite (furrows, alveolus, siphuncle) - I'm very tempted to just call it a suggestive crystalline rock. Perhaps @Jeffrey P could chime in. 1 ~ Isaac; www.isaactfm.com "Don't move!

Jeffrey P Posted July 19, 2022 Share Posted July 19, 2022 I don't see a tooth or a belemnite guard. The streams in Monmouth County produce a multitude of stones (ironstone concretions from the marl and glacial transported debris) that resemble fossils, but aren't. Good luck and keep searching. 2 1 Link to comment Share on other sites More sharing options...

marcltetreault Posted July 19, 2022 Author Share Posted July 19, 2022 No reaction to white Vinegar at all. That means it’s not calcite, right? Link to comment Share on other sites More sharing options...

Quartz is most likely and what I suspected. I don't think this is a fossil. 2 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
