Fin Lover Posted August 2, 2022 Share Posted August 2, 2022 I have one other shark tooth from Sunday that I cannot ID. Found in the same creek as the retroflexus, but not necessarily the same formation. Thank you so much!

debivort Posted August 2, 2022 Share Posted August 2, 2022 My guess would be Bull Shark. The lack of a nutrient groove is throwing me a bit, but maybe that's just the photo. 1 Link to comment Share on other sites More sharing options...
Fin Lover Posted August 2, 2022 Author Share Posted August 2, 2022 I've looked at several Carcharhinus species, but there is always something that throws me off (usually the bulge/cusp). Definitely doesn't have a nutrient groove. Thanks! Fin Lover My favorite things about fossil hunting: getting out of my own head, getting into nature and, if I’m lucky, finding some cool souvenirs.

Fin Lover Posted August 2, 2022 Author Share Posted August 2, 2022 Sorry, I should have added that the genus is all I'm looking for. I know it's difficult to narrow down to Carcharhinus species, if that is what it is.

debivort Posted August 2, 2022 Share Posted August 2, 2022 Yeah, those shoulders (if that's what you mean by bulge/cusp) are intriguing. Not a terrible match to the shoulders of this tooth from https://www.fossilguy.com/gallery/vert/fish-shark/carcharhinus/index.htm Your tooth doesn't have any of the central wrinkling at the base of the enamel on the labial side.

Fin Lover Posted August 2, 2022 Author Share Posted August 2, 2022 Yes, the shoulders. I looked at that same picture earlier but my root comes down to a point in the center. Doesn't mean that's not what it is, but that's part of why I'm stuck.

A few of the examples on that fossilguy image have a similar point of root (the top left and bottom left, for example). 1 Link to comment Share on other sites More sharing options...
Meganeura Posted August 2, 2022 Share Posted August 2, 2022 I'm gonna throw a Carcharhinus sp. into the ring and call it a day - looks like plenty of my other of that genus that I have. 1 1 Fossils? I dig it. Link to comment Share on other sites More sharing options...
Fin Lover Posted August 2, 2022 Author Share Posted August 2, 2022 Thanks! That was my guess, but both of my guesses on my last ID request were wrong, so I decided not to open with that. It's definitely my largest Carcharhinus then. 1 Fin Lover My favorite things about fossil hunting: getting out of my own head, getting into nature and, if I’m lucky, finding some cool souvenirs.

Yeah an inch long Carcharhinus is a pretty nice find! I think that beats my biggest, I'll have to check. Fossils? I dig it. Link to comment Share on other sites More sharing options...
Fin Lover Posted August 2, 2022 Author Share Posted August 2, 2022 Thank you, both. The local book I have shows the C. leucas getting right over an inch, so I think that's probably the most likely candidate. Just has some interesting shoulders (or I have others with similar shoulders that were just much smaller teeth, so I didn't notice them).

Fin Lover Posted August 2, 2022 Author Share Posted August 2, 2022 Yes. It was recommended to us when we first started looking on the beach. It works well if your tooth looks like the one or two examples in the book. But, I'm new enough to this that if it doesn't match, then sometimes I don't even know where to begin the Google search. I'm sure it just takes more experience. 1 1 Fin Lover My favorite things about fossil hunting: getting out of my own head, getting into nature and, if I’m lucky, finding some cool souvenirs.

debivort Posted August 2, 2022 Share Posted August 2, 2022 I would love a book that has full dentitions for every species. 2 Link to comment Share on other sites More sharing options...
