Cretaceous shark tooth

[Kev]

 Any ideas what type shark? Found in Alabama. I believe it to be cretaceous based on baculite shells found nearby.

My guess is a lateral Scapanorhynchus or a Cretolamna tooth but without the cusps and root I can't tell which.

Don't think it's goblin (no striations and seems too thick). I think it could be Cretolamna or Cretoxyrhina but can't tell which without the whole tooth. Could also be other lamnids but can't really say without better locality.

Scapanorhynchus laterals don't have striations except for the edges where the crown and root meet, that area missing/eroded in the specimen. It does seem a little thick. As you said it's just a guessing game without the rest of the tooth.
