Megalodon Shark tooth fossils typically date from the Early Miocene to the end of the Pliocene epochs, spanning a huge period of approximately 23 to 3.6 million years ago. The fossil teeth are well-preserved because their dense composition, mainly dentin, mineralizes over time (permineralization). Scientists use the tooth's colossal size and features—specifically measuring crown height or width—to estimate the shark's total body length, which is thought to have reached up to 50 to 60 feet for the largest individuals. Furthermore, the development of full and uniform serrations over this multi-million-year period reflects an evolution toward a more specialized, single-strike hunting style to prey on large marine mammals like whales.
