While out on one of the small "islands" off the coast of Wrightsville Beach, Wilmington, North Carolina- yesterday morning I found this tooth. I have quite a few teeth and various fossils but something about this one feels different. I'm sure everyone says that but I have gone through various shark i.d. questionnaires and can't get a specific conclusion. I've had suggestions from an ancient "cow shark" type species (I think bc I answered "yes" to present cusplet) but there is clearly one and it doesn't appear another broke off- which makes me think age is a factor (as in this could've belonged to a juvenile as opposed to an adult). The back is not completely flat but no serious pronounced shapes, the root is large and in tact with no visible foramen (in human biology a foramen is basically a hole so I'm making the same assumption or odontological guess) and there is not a nutrient line, crown and neck present, serrations continue on both sides of the tooth (I am including two copies of the same photo to show the original with a shadow; but if magnified the serrations are more clear and then a clearer shot that unfortunately didn't 'cut' the black shadow from the serrations. A genus I keep finding is Carcharhinus and hopefully someone has some ideas. Cheers! Becky

Why are mesial serrations more worn than distal?
Nanotyrannus35 posted a topic in Questions & Answers
This is kind of an oddly specific question, but out of the four theropod teeth that I have, all of them have the mesial serrations worn down, while the distal are pristine. Is this due to feeding wear? Or environmental factors? Could it possibly be that the mesial serrations are more fragile? Thanks for any answers. -
Hi just got these two fossils today! And was wondering did I get it right on saying this Daspletosaurus tooth was a mesial tooth? Also i called it a Daspletosaurus because it’s DSDI was over 1.2 and I think it’s a mesial tooth. In the photo it’s beside my smaller Judith River Tyrannosaur indet tooth. Also is it possible to tell what this dinosaur finger bone is? Thank you! dinosaur finger bone
