Hastalis (broad toothed mako/narrow white) or Plicatilis (giant white)

My daughter found this slightly over 2 inch tooth diving off Venice Beach, Florida in March.  Boat operator and I both immediately thought it was a hastalis (broad toothed mako/narrow white).  However, now that I have been reading more on great white lineage and evolution, I’m wondering if it’s perhaps a plicatilis (giant white).  Or…are those two actually the same?  Any help appreciated…thank you!

 

here’s the link that got me wondering:

Extinct white shark naming and taxonomy is a can of worms. I don't believe C. plicatilis is widely used today as many authors consider it synonymous with C. hastalis, I personally refer to these white shark teeth as Carcharodon hastalis
