A vertebrate fossil that is not a shark or ray tooth: collecting it on Florida state land or water, including beaches below the high-tide line, requires a Florida Museum Fossil Permit. Teeth from modern whales are protected by federal law — never keep them.
How to tell it apart
- Large, heavy, curved cone
- Mostly root with a small worn enamel cap
- Concentric growth rings where broken
