Hey Molly! I’m still leaning towards Great White, but to confirm… Along the margin near where I’ve outlined in red there appears to be something black. By any chance, can you tell if the black is enamel? If so, that would be referred to as the bourlette, which is a diagnostic feature for Megalodon. The second image I attached shows a good example of the bourlette in Megalodon. If it’s not enamel, then that is certainly a Great White. The problem is that the bourlette is a thinner layer of enamel that can wear away, particularly when the root is damaged to the extent this one is. Awesome find either way though!
