mEGALODON TOOTH

South Carolina, USA

Early Miocene to Pliocene (23 - 3.6 Million Years Old)

Megalodon (Otodus megalodon) was one of the largest and most powerful predators to ever exist. It lived between 23 - 3.6 million years ago and probably had a huge impact on marine communities, with whales, seals and sea turtles being its most likely victims.

Megalodon teeth are found worldwide and can measure up to 7 inches in length. However as sharks have cartilagenous skeletons which do not fossilise like bone, Megalodon is only known from its teeth and vertebrae. This makes estimating its true size tricky, but it is mostly agreed that Megalodon measured between 14.2 and 20.3 meters.

The Megalodon tooth you've scanned comes from South Carolina. As the coastal areas of South Carolina were once a seafloor, the river beds there are home to many fossil shark teeth, including those of Megalodon.  Other fossil remains, such a vetebrae of the whales which Megalodon once preyed upon, can also be found in these river beds.

Megalodon had the largest teeth of any known shark, with the largest measuring over 7 inches in length.  Its teeth were triangular in shape and serrated. The lingual side of its teeth (the side facing the tongue) were convex while the other side was mostly flat. Almost all Megalodon teeth are found in isolation, however there have been instances where nearly complete sets have been found.
