BellamyBlake Posted January 22, 2021 Share Posted January 22, 2021 I have a 2.96" Cosmopolitodus hastalis from Beaufort County, South Carolina. It has a cut across the root. It looks similar to bite marks I've seen, however those have been on parts of the tooth that make sense like the blade. Is this a bite mark? If so, how would it get on the root?

ThePhysicist Posted January 22, 2021 Share Posted January 22, 2021 I think that's a boring - it looks more like a cavity rather than a cut; closeups would be helpful. I would guess that bite marks could still happen on the root if the tooth managed to stay inside the mouth long enough after it fell out, though most bite marks I've seen were on the crowns.

Thomas.Dodson Posted January 22, 2021 Share Posted January 22, 2021 I'm thinking boring as well but a closeup might help. Link to comment Share on other sites More sharing options...
Bails Posted January 22, 2021 Share Posted January 22, 2021 Not to hijack the thread but I’ve been wondering what might have caused this indention in a big hastalis I recently found. Any ideas? Link to comment Share on other sites More sharing options...

I have a few closeups, as close as I can get without it blurring up. Please let me know what you guys think. Link to comment Share on other sites More sharing options...

Please let me know what you guys think. I'm thinking boring even more now. The irregularity of the cavity outline and the shallow end of it are pretty consistent with what I see with borings. 1 Link to comment Share on other sites More sharing options...

Sometimes scrapers and borers make for very interesting and varied fossils. Here's a shameless plug of a gorgeous scraped bone from a recent trip I did. 1 Link to comment Share on other sites More sharing options...

Any ideas? From the pics it looks like a potential pathology - happened when the tooth was being grown.
