fossilsonwheels Posted July 1, 2019 Share Posted July 1, 2019 I saw this little lot of small teeth and instead of guessing I decided to seek some help on the ID. I do not have a lot of information. They are from the Dallas area, near the airport. The original collector believed it was Woodbine formation. most of the pictures were similar angles as well. My knowledge on Texas sharks is fairly limited. I do think the larger one is Scapanorhynchus. Outside of that, I really have no clue. Any help would be much appreciated.

fossilsonwheels Posted July 2, 2019 Author Share Posted July 2, 2019 Doing some research and I am pretty sure (75%) that one of these is a Serratolamna and one is Odontaspis. I am leaning toward Paranomotodon on another. Is the odd looking tooth a Scapanorhynchus symphyseal maybe? Link to comment Share on other sites More sharing options...
Captcrunch227 Posted July 2, 2019 Share Posted July 2, 2019 So little is known about the Symphyseal teeth from here. I’ve had a devil of a time trying to find info on properly identifying them. As of right now I don’t think it’s possible to put a label on the symphyseal teeth. Ive found about 8 this past year and no luck getting anything close. I spoke to Roger Farish about it a few months back and he echoed the same. It’s possible to limit the field to a handful of sharks on the bigger symphyseal’s but it’s near impossible on the little teeth. Link to comment Share on other sites More sharing options...
Captcrunch227 Posted July 2, 2019 Share Posted July 2, 2019 This almost looks like Leptostyrax but it’s almost impossible to tell without photos from the backside. Link to comment Share on other sites More sharing options...
Al Dente Posted July 2, 2019 Share Posted July 2, 2019 The one I circled is Abdounia, an Eocene species. Probably not from Texas. 1 Link to comment Share on other sites More sharing options...
MarcoSr Posted July 2, 2019 Share Posted July 2, 2019 I agree with Eric on the Abdounia tooth. All of these teeth look like Eocene species to me. These teeth are identical to those that I see come from the Nanjemoy Formation in Virginia and that is where I think they are from. Marco Sr. 1 "Any day that you can fossil hunt is a great day."

Marco Sr. The seller does have lots of Miocene teeth from Virginia so this may be just a mislabeled bunch. I am glad I posted this one.

I sent George lots of matrix from the Nanjemoy Formation of Virginia years ago which these teeth probably came from. Marco Sr. 1 "Any day that you can fossil hunt is a great day."

I would be VERY interested I am currently working on expanding the Cretaceous area of our shark program so that would be incredibly helpful Link to comment Share on other sites More sharing options...
