Shark Tooth Hill Thresher?

[Calvin Jenkins]

This came from Ernst Quarries last year at slow curve.

 

I don't think this is a hooked Mako because of the micro serration on both sides of the tooth, so what is it?

 

I know I failed to include a scale but this tooth will just cover an American Quarter.

 

Thanks in advance!

Hi There,

 

  Not as familiar with the fauna of STH .. but that looks like a Physogaleus contortus. Tiger-like shark.

 

Cheers,

Brett

Here is an example of one that @ynot has from the location...

As ynot said exactly. Physogaleus contortus, an extinct tiger-like shark. It was at one time in the genus Galeocerdo. They are very common in the Miocene sediments here in North Carolina, but I do not think they are as common at Shark Tooth Hill.
