FossilizedShoe Posted October 8, 2020 Share Posted October 8, 2020 (edited) I found these two teeth on a recent fossil hunting trip in the Charleston, SC area. The tooth on the left is 15mm and the tooth on the right is 13mm. Edited October 9, 2020 by FossilizedShoe wrong measurements Link to comment Share on other sites More sharing options...
Coco Posted October 8, 2020 Share Posted October 8, 2020 I don't know the species, but the one on the right side could be a symphyseal tooth.

Coco That's interesting. The enamel portion does not seem to be malformed, though, so I'm not sure if it's a patho or just a weird position of a less common species Link to comment Share on other sites More sharing options...
PrehistoricWonders Posted October 9, 2020 Share Posted October 9, 2020 I’d guess the one on the left is a juvenile great white tooth, I’m not positive on the one on the right, but I’d guess either syphyseal megatooth shark tooth or symphyseal great white.

Coco Posted October 9, 2020 Share Posted October 9, 2020 Hi, Yes, the one on the right side isn't a pathological one.

The closest match to a modern tooth would be C. altimus or maybe C. acronotus. 1 Link to comment Share on other sites More sharing options...

Coco Posted October 9, 2020 Share Posted October 9, 2020 Both are recent species (C. altimus and C. acronotus).

hemipristis Posted October 10, 2020 Share Posted October 10, 2020 the left one reminds me of the sandbar shark Carcharhinus plumbeus. Is it very thin in cross section? 1 'Those who cannot remember the past are condemned to repeat it.' George Santayana Link to comment Share on other sites More sharing options...
