Megatooth Shark Comparison
Occasionally, teeth of the two sharks, Carcharocles megalodon and Carcharodon carcharias, may be confused for one another. Ususally, this is a problem with a worn or otherwise damaged tooth . . . especially where the teeth of the two sharks may be found together, as in Florida's Peace River (C. carcharias teeth are uncommon in the Peace River). Megalodon and the great white shark now are generally believed to be not closely related.
