hemipristis

Recommended Posts

Found this in the Pungo River Fm of Lee Creek (Miocene). I'm pretty sure it's a Carcharhinid, and more than likely a lower tooth, but that's all I got. Half-inch in length, smooth cusp (even under micro), strong foramen, curved root base.   Maybe there is a slight notch in the blade (left side, labial view), but I can't be sure that's not a nick.

 

My first thought was Lemon Shark, but the tooth is too triangular, and the base of the root has a very definitive curve. Then I thought hammerhead of some sort.

Photos in order: Lingual, Labial, side

 

Ideas?

I agree.

Bulldozers and dirt Bulldozers and dirt
behind the trailer, my desert
Them red clay piles are heaven on earth
I get my rocks off, bulldozers and dirt

Upper lateral lemon shark.  Note the triangular tooth about mid-way down the jaw:

Yup, thanks!  I've done most of my tooth collecting in MD/VA/NC, and there aren't many lemon teeth to be had there, so I'm not as familiar with them.

 

Appreciate it

hemipristis is correct. :) 

Great find! 

:headscratch:Hemipristis (snaggletooth) is not correct for a lemon shark.
