fossil_sea_urchin Posted November 30, 2019 Share Posted November 30, 2019 Hi, I found this while looking through some North American cretaceous gravel along with a serrated rex tooth fragment. Does anyone think it's a pterosaur tooth or a mineral, apologies if the pictures aren't good thanks in advance. Link to comment Share on other sites More sharing options...
caldigger Posted November 30, 2019 Share Posted November 30, 2019 Enlarged and brightened. The bottom picture doesn't seem like a natural mineral to me, nor does it look like a tooth. Not quite sure what it is. 1 Link to comment Share on other sites More sharing options...
Pterygotus Posted November 30, 2019 Share Posted November 30, 2019 Not mineral. May be too fragmentary to be identified at family level. 1 Link to comment Share on other sites More sharing options...
Rockwood Posted November 30, 2019 Share Posted November 30, 2019 It's easier for me to imagine ossified tendon with the spiral look. 1 Link to comment Share on other sites More sharing options...
LordTrilobite Posted November 30, 2019 Share Posted November 30, 2019 A different area entirely but this kinda reminds me of Onchopristis sawfish teeth from Morocco. Along the bottom half of the tooth those have similar slightly twisting edges and fluting. 2 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

I think you mean order in the scientific term, but yes, I understand. Link to comment Share on other sites More sharing options...
jpc Posted November 30, 2019 Share Posted November 30, 2019 any chance you could post closer-up pix? The thing is pretty unusual for deposits that would also give you rex frags. 1 Link to comment Share on other sites More sharing options...

I was meaning towards this too but also think there is the possibility of hybodont spine. 2 Link to comment Share on other sites More sharing options...
