One more Tooth Ache??

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

I can imagine the minerals of a belemnite guard degrading to this point. ' can't really identify it as such though. :Confused05:

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.  :look:

I don't think it is a tooth. No enamel present.

My first thought was very worn/split belemnite guard. :unsure:

 

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.

 

Cropped and color corrected:

The folding of the (possibly) calcite (could also be some silica based one, like quartz?) - yeah, let's just call it crystal right now... :BigSmile:

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 

Descriptive terminology of belemnite rostrum morphology based on... |  Download Scientific Diagram

 

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.

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.

Thank you…. I have to figure out how to save and access all this great information I am being sent.

I often quite like to write little word documents, or write in poster style, so I can print it out and flick through them - I very much enjoy making diagrams, and find it helps me remember a lot :P

Did it react to vinegar?

We've all been there - I'm there right now, meant to be coding for a website... :duh2:

 

Right, let's actually knock this down then, see y'all later!

No reaction to white Vinegar at all.  That means it’s not calcite, right?

Correct.  Quartz is most likely and what I suspected.  I don't think this is a fossil.
