New Jersey Cretaceous shark tooth ID

[frankh8147]

Hello! I recently found this TINY (the entire rock is about the size of a U.S. half dollar) shark tooth in matrix. It is from the Monmouth County Cretaceous. It has two cusps on either side, they are partially covered in the matrix but I'm having difficulty removing it so I am not planning any further prep. Anyone know what type of shark this is?

An US half dollar doesn't speak to the numerous foreigners here...

Dear frankh81467, 

 

That's a lovely lower posteriormost Scapanorynchus texanus tooth! It isn't often you find those in such good condition. I've collected several in my time for the museum, and all have their lateral cusplets missing. Congratulations! 

 

Regards, 

 

Chase

Right! The entire rock roughly an inch (2.5 centimeters) long, the tooth itself is tough to measure - it's really, really small! thanks

Looks like Eostriatolamia holmdelensis. Need to see other side to be sure. If there were more cusps, I would say Odontaspis aculeatus.

Or even to most younger Americans who have probably never seen one.

Under used bit of currency, the half dollar. Nice tooth!

I have to go with Al Dente on this tooth.

Thanks everyone!

I agree with Odontaspis aculeatus. It's too small and its cusplets are too big to be Eostriatolamia holmdelensis. If the lingual side of the tooth has no striations then it's definitely Odontaspis and not Eostriatolamia.
