    This tooth, "pseudohypolophus" has yet to be assigned to a family. It is believed to be an extinct Rajiforme, specifically a guitarfish. Tooth crowns are very common in Black Creek sands, but are very rarely found with the roots.

    @sassyandrea337 What you are finding on Florida beaches are most likely Miocene / Pliocene drumfish teeth. This tooth is from a Cretaceous Guitarfish. It is similar in size and shape but not the same. There are no Cretaceous deposits in Florida.
