Hi, @bradley-meyers – do you have a photo of the other side of the tooth you could upload? That will help our experts confirm your fossil identification! Talk to you soon, Jen

The image is unclear and very contrasty. I sharper picture with less contrast would allow better identification. You can use any of many image processing programs (many of which are free on the internet and some included in versions of Windows, Apple, or even on phones) to adjust the contrast.

Hi, @bradley-meyers – this is not a horse tooth but rather a ray plate. Your classification is very incorrect.
Kingdom Animalia > Phylum Chordata > Class Chondrichthyes > Order Myliobatiformes.

Hi, @bradley-meyers – you can use Macrostrat to get a better idea of the age of the rock: https://macrostrat.org/map/#/z=10.6/x=-82.3217/y=29.7107/bedrock/lines/ just find the locality you were at and click!

Do you have an image of the other side of the specimen you could upload?

Galeocerdo is a tiger shark which have very distinctive teeth. This is not a tiger shark but instead a lower Carcharhinus species. From the lower teeth (which this is), it is usually (there are a few exceptions) to narrow down the exact species. Due to the wide root, it is possibly (possibly) a Sandbar Shark tooth (Carcharhinus plumbeus).
