Recently Acquired Dolphin Tooth from Florida

[lesofprimus]

I just received this Odontocete/Dolphin tooth from Gainesville, Florida and I'm having a hard time trying to identify it, no matter how much I search the internet...

 

It meadures 1.92" at it's longest point and hopefully the experts here, @Boesse can shed some light on this very unique and beautiful tooth.

A fellow Florida collector has recommended Delphinodon dividum as the likely identification.

This is not Delphinodon - Delphinodon is quite tiny. This is some kind of large and longirostrine odontocete, perhaps Goniodelphis - the teeth are a bit too large for Pomatodelphis.
