North Carolina Auriculatus 2.62"

It's been quite a few years since teeth from this unknown location were on the market. This is one secret the diver never divulged. 
Some feeding wear along the side. Fairly wide tooth for it's size.

Carcharocles sokolowi (also known as Carcharocles auriculatus) was an early megatoothed shark and a distant ancestor of Megalodon. It lived around 40 million years ago during the Eocene epoch, patrolling prehistoric oceans as a top predator. Its teeth are known for their sharp serrations and distinctive side cusps, traits that gradually faded in later species. Fossils of this shark have been found in various locations around the world.
