Giant 6.15" Fossil Sperm Whale Tooth

This is a giant Miocene aged fossil sperm whale tooth that was found in a river in NE Georgia associated with shark teeth including Megalodon. It's pretty worn but is a huge tooth at 6.15 inches in length.

While the tooth came from a sperm whale, identifying it to the genus level is impossible. This is because there were 14 known genera of Sperm Whales living in the past compared to 2 today. The size and shape of teeth between these types overlap significantly.
