readinghiker Posted May 13, 2021 Share Posted May 13, 2021 This final fossil could very well be a dermal denticle. However, if it is, it is the most robust denticle that I have seen. It is quite large for a denticle as well. Any other possibilities? Link to comment Share on other sites More sharing options...
Coco Posted May 13, 2021 Share Posted May 13, 2021 (edited) I think that’s it. Some current skates (Raja clavata) have some denticles at least 1 cm in diameter...

readinghiker Posted May 15, 2021 Author Share Posted May 15, 2021 Thanks! I do think that this is a dermal denticle. But it is far larger than the other few denticles that I have found. Link to comment Share on other sites More sharing options...
