Robin252 Posted January 28, 2018 Share Posted January 28, 2018 (edited) Found this tooth in GMR in eastern North Carolina today. Some have suggested a mosasaur tooth or a gator tooth. The back is missing, but there is still a curve on the tooth. Thanks for looking. We also found belemnites upstream from here.

Darktooth Posted January 28, 2018 Share Posted January 28, 2018 If I remember correctly mosasaur teeth have a cutting edge on the front of the tooth and gator do not. It is pretty worn but you can see stiarations at the base so it may be gator. I am no expert though. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...

Anomotodon Posted January 28, 2018 Share Posted January 28, 2018 I could be very wrong, but it reminds me of a very worn Ischyrhiza rostral tooth root. Curvature could be postmortem or pathological. Maybe pictures of the base would help. 2 The Tooth Fairy Link to comment Share on other sites More sharing options...
Macrophyseter Posted January 28, 2018 Share Posted January 28, 2018 It seems to me that it might be a rooted alligator/crocodile molar/premolar with a really worn crown. The shape, curvature, and striations of much of the tooth, especially the left end/bottom part, is almost identical to my three modern rooted alligator premolars. The crown (small part of tooth above/right of the constriction) seems to be simply worn down and lost enamel (hence it's similar texture with the root). Here are my three modern alligator premolars for comparison. Notice the similar shape and curvature (unfortunately, the white color of the tooth makes the camera not able to capture the striation details clearly, so this is the best I can get.), and if you can manage to get the details, the striations. On the left are my Pleistocene Alligator anterior teeth, which have lost enamel. You can also notice the similar texture of the enamel-less teeth (Look at the light reflection to see some of the details) However, I am not an expert and this is a guess based on anatomic comparison. Others may have some different says, so remember to consider other's opinions before you ID! 1 If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM!

Robin252 Posted January 28, 2018 Author Share Posted January 28, 2018 Thanks for the input. Here's a look at the base. It's broken on the back. Link to comment Share on other sites More sharing options...
Max-fossils Posted January 28, 2018 Share Posted January 28, 2018 Welcome to TFF! Am I the only one that is seeing possibly a mammal tooth in the second picture of the reply just above??? That curvy edge really reminds me of the edge of enamel mammals often have... I might be completely off though. Max Max Derème "I feel an echo of the lightning each time I find a fossil.

Now I definitely see that it is not a sawfish The Tooth Fairy Link to comment Share on other sites More sharing options...

sixgill pete Posted January 30, 2018 Share Posted January 30, 2018 @jpc GMR, or Greens Mill Run; in Greenville North Carolina. The formations here;all mixed together in a big smorgasbord, include Cretaceous, ?Eocene?, Miocene, Pliocene and Pleistocene. I do not think the tooth is croc / alligator nor mosasaur. The thought of it possibly being a well worn and broken I. mira rostral tooth is rather intriguing. I have found some very large ones in this creek. All worn, broken or both. Mammal teeth from the Pleistocene are not unheard of and I have seen at least 2 different giant beaver teeth from here. Honestly though, I think the fragment of tooth is too worn and broken to get a positive I.D. on; all would just be speculation.

Plax Posted January 30, 2018 Share Posted January 30, 2018 (edited) six gill is correct. I'd bet 10 bucks maybe but not the house on this ID. The pic is really reminiscent of the pic of I. mira by Leidy? from NC. Wish I could remember where I saw that pic. That was Emmons not Leidy...

sixgill pete Posted January 30, 2018 Share Posted January 30, 2018 The more I look at the picture of the base of this broken tooth, and yes I do believe it is a tooth, the more it does in fact look like Ischyrhiza mira to me.
