Everyone wants to find fossil shark teeth and a Megalodon tooth would be at the top of everyone’s list for fossil shark tooth hunters. Why not? It was the apex shark predator which possessed big, wide serrated teeth that can reach 7” in length. This tooth would be a true center piece item for any shark tooth collection. Unfortunately, Megalodon teeth are one of the more difficult fossil shark teeth to self-collect even in the US which produces more Megalodon teeth than the rest of world combined. So you want to find a Megalodon tooth? The first rule for finding a Megalodon tooth, is to look where sediments of Miocene and Pliocene age formation are exposed, and these sediments must be marine in origin.
