HemiHunter Posted September 19, 2020 Share Posted September 19, 2020 Hey Guys! I've been going through some of our Calvert Cliffs summer finds and came across this one that I can't ID. It looks like it has a couple of teensy cusplets, which is probably a useful clue for somebody who actually knows their stuff. Any ideas? 1 Link to comment Share on other sites More sharing options...

Any ideas? Posterior Isurus sp. and C. hastalis teeth , it is not uncommon for them to have small cusps on either side of the blade. Could be a possibility.

I agree with lateroposterior C. hastalis, looks as though it may be a juvenile as well. Vestigial cusplets are not uncommon in juveniles. Nice tooth! 1 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

HemiHunter Posted September 24, 2020 Author Share Posted September 24, 2020 C. hastalis it is then. I would never have figured that out on my own. I've had good luck this summer with a few cool posteriors. Thanks guys! Link to comment Share on other sites More sharing options...
