Moses Oberlander Posted April 27, 2021 Share Posted April 27, 2021 Hi, I found all these teeth at Big Brook in NJ I know that they are mostly or all shark teeth but I would like to know more info and species if anyone is willing to help, thanks!

ThePhysicist Posted April 27, 2021 Share Posted April 27, 2021 Hello, and welcome to the forum! I'm not an NJ native, but hunt in a similar age and environment. The ones not circled are not enough for me to positively ID, or I don't know. These are all shark teeth, and I'll give a basic rundown: Scapanorhynchus sp. ("goblin shark"): http://www.fossilsofnj.com/shark/goblin.htm Squalicorax sp. ("crow shark"): http://www.fossilsofnj.com/shark/crow.htm Cretolamna sp.: http://www.fossilsofnj.com/shark/cretolamna.htm Archaeolamna sp.: http://www.fossilsofnj.com/shark/archaeolamna.htm Sand tigers: Eostriatolamia sp.: http://www.fossilsofnj.com/shark/c_holmdelensis.htm, Odontaspis sp.: http://www.fossilsofnj.com/shark/o_aculeatus.htm Hopefully someone who is more familiar with the site can confirm/refute these ID's. 4 1 1 "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...

Thomas.Dodson Posted April 28, 2021 Share Posted April 28, 2021 I agree with ThePhysicist's IDs. The small tooth on the left of the "Sand Tigers?" group looks like it could be Squatina sp. which would make it Squatina hassei from Big Brook. A quick search suggests that the Scaphanorhynchus and Cretolamna species present in Big Brook are the typical texanum and appendiculata (same as the links ThePhysicist shared). I'd guess you have mostly Squalicorax kaupi but S. pristodontus is also found there. The links above show how to differentiate the two when the roots are intact. Lastly, here's a Big Brook guide that goes over species found there. https://www.fossilguy.com/sites/bbrook/bbrook_col.htm#shark 1 Link to comment Share on other sites More sharing options...

I'm just guessing based on what looks like a massive root. 1 1 Link to comment Share on other sites More sharing options...
