Yes, Megalodon, prehistoric Great White. There are MANY to be found while diving offshore of North Carolina.
Very nice find! I agree with the others that this tooth is a Great White rather than a Megalodon. In most areas, the Great White teeth are less common than Megalodons. Estimated age 10-15M years old, Miocene.
Yup very cool...i learned to dive when i was 13 just so i could dive the cooper river for sharks teeth.....good times
Nice find!
