John Hamilton Posted August 23, 2013 Share Posted August 23, 2013 (edited) I'm posting better photos hoping to get a positive ID on this tooth. I originally thought it might be a symphyseal tooth and Don (aka sixgill pete) thought it might be an archeolamna kopengesis. Please let me know your thoughts on this tooth and as always thanks for looking. Edited August 23, 2013 by John Hamilton Link to comment Share on other sites More sharing options...
Gizmo Posted August 23, 2013 Share Posted August 23, 2013 Do you think that everything above the crown is root material ? Could it be a tooth imbedded in a concretation? Link to comment Share on other sites More sharing options...
Al Dente Posted August 23, 2013 Share Posted August 23, 2013 I think this is just a fragment of a larger tooth. Here is a Scapanorhynchus from the Elasmo website. I think you have the side cusps with a chunk of root attached. Link to comment Share on other sites More sharing options...

Yes, I do think everything above the crown is root material. Link to comment Share on other sites More sharing options...

I see a tooth that has a missing cusp on one side. Link to comment Share on other sites More sharing options...
sixgill pete Posted August 23, 2013 Share Posted August 23, 2013 John, after looking closely at the photo's you posted here and observing Al Dente's post, I am leaning towards his thought. Here is your picture with my thoughts on it.

After further review I concur with your response. I increased the magnification and clearly see that this is a broken piece of the root.
