Collecting
Check local rules

Florida needs no fossil permit for shark teeth, but state parks, national seashores and wildlife refuges don't allow collecting, and private land needs the owner's permission.

Handling
Sharp edges

How to tell it apart

  • One long pointed cusp on a broad base, with no side cusplets
  • Smooth, non-serrated cutting edges
  • Relatively thick front-to-back rather than blade-flat

Commonly confused with

  • Lemon Shark ToothNegaprion brevirostris

    A smooth, narrow cusp alone doesn't make it an angel shark tooth: lemon shark teeth look similar, and upper lemon teeth can have finely serrated bases. Angel shark teeth are thicker front-to-back.

  • Sand Tiger Shark ToothCarcharias taurus

    Look for tiny side cusplets beside the main cusp: they point to sand tiger, not angel shark. On a worn or broken tooth, missing cusplets alone don't settle it.

  • Atlantic Sharpnose Shark ToothRhizoprionodon terraenovae

    Sharpnose teeth lean to one side and have a notch on the outer edge. An angel shark tooth has one long pointed cusp standing on a broad base.
