Caaaleb Posted June 29, 2022 Share Posted June 29, 2022 (edited) Hello! I went out to Post Oak Creek in Sherman, Texas, this April and I found my first batch of shark teeth ever, about 46 teeth! I got some pictures of the six main ones I found interesting and that I would like y'all to ID for me. Thanks! (1/2) (3) cutie (4) Shark or Mosasaur? (5) These three goobers (6) Biggest boy I've ever found! Edited June 29, 2022 by Caaaleb 2 Link to comment Share on other sites More sharing options...

jikohr Posted June 30, 2022 Share Posted June 30, 2022 Hi, nice teeth! The first two are from a crow shark, genus Squalicorax. third one is from a Mackerel shark of some sort, could be a symphyseal tooth which is from where the jaws meet. fourth is also mackerel shark, hard to say without the root what species though. Leaning towards Cretalamna since that's the most common one there with a crown like that in my experience but impossible to say for sure without a root. the goobers are either sand tiger or goblin shark, need clearer pics to say for sure but leaning toward sand tiger. sixth is definitely goblin shark, Scapanorhynchus texanus. 2 Link to comment Share on other sites More sharing options...

Awesome, Thank you! I assumed the first two were either Squalicorax or Pseudocorax Link to comment Share on other sites More sharing options...
ThePhysicist Posted July 1, 2022 Share Posted July 1, 2022 3 looks like a Cretodus symphyseal - super jealous, that's on my to-find list. 5 are goblins - I've yet to find/see definitive sand tiger teeth in POC. 3 "Argumentation cannot suffice for the discovery of new work, since the subtlety of Nature is greater many times than the subtlety of argument." - Carl Sagan "I was born not knowing and have had only a little time to change that here and there." - Richard Feynman Collections: Hell Creek Microsite | Hell Creek/Lance | Dinosaurs | Sharks | Squamates | Post Oak Creek | North Sulphur River | Lee Creek | Aguja | Permian | Devonian | Triassic | Harding Sandstone Instagram: @thephysicist_tff Link to comment Share on other sites More sharing options...

I agree. I have what I think is a Cretodus parasymphyseal from Amon Carter Field that looks like that. 2 Link to comment Share on other sites More sharing options...
