Chubutensis or angustidens?

I just got this pretty 2.5" pungo river tooth in the mail yesterday. What do you guys think, chub, angy or somewhere between?

 

cheers!

 

edit: sorry, photos didn't upload. Here they are...

Nice tooth Russ! Not sure on the id.  But I am sure it's a sweet acquisition!

If it is Pungo River, it is O. chubutensis. Pungo River Formation is Miocene. O. angustidens are from the Oligocene.

Funny ....  Those cusps are screaming Angustidens because they are so pointy and separated from the main blade.  Curious if the formation designation is incorrect. I'm no expert but those Chubs have cusps that are usually fairly incorporated into the main blade and are usually curved and better incorporated.  I'd be curious what others have to say, is it transitional ?

 

Cheers,

Brett

Here's the data that it came with. Good info posted here, thanks guys. I'm also interested in hearing what anyone thinks of the tooth, accuracy of the data or any other insight you might have.

 

cheers!

@Brett Breakin' Rocks The tooth has the color, shape and root of a classic Lee Creek "pungo" chub. As far as the cusps, well no two teeth look identical. I have angustidens from the early Oligocene that look like auriculatus and late Oligocene angy's that look more like chubs. 

 

You could get nit picky and call it a "transitional" tooth if you want, but if it is from the Miocene Pungo river Formation like the label says, it is Otodus (Carcharocles) angustidens.
