"Meg Ledge" Meg or Chubutensis?

I got this from a local "Meg Ledge" diver. It looks like a Meg posterior tooth, but I'm not sure it's not a Chubutensis posterior, given what looks like vestigial cusplets. Thoughts?

I would call it chubutensis based on the swelling/cusplet up by the root. The transition from chub to meg occurs in the Pungo River Formation (and the Calvert Formation farther north). Some partial dentitions have been found that have cusplets on some of the teeth but not on all, so what you call a particular tooth doesn't really matter as there was only a single species present at any time.

Thank you for the replies. One vote Meg, one vote Chub. Any others?

 

This issue begs the question, are Chubutensis teeth known to have been found at any of the Meg Ledges in North Carolina? I've read one account that says yes...

I think that meg vs. chub is a gray area and probably not something you can make a definitive answer on.

Yes,  I agree. I can only say what my experience is on the Peace River in Bone Valley Florida.  About 10 years ago I found this shark tooth... 

The Peace River can be Miocene in age and is known for Megalodons. NO verified Chubs. There are rumors that a few larger Chubs have been found in phosphate mines,

This tooth is just under 2 inches. I have found 25-30 similar shark teeth with cusps always under 2 inches.  It has been said that these are Megalodons with recessive genes.  

With that background , I have always labeled them as Megalodons,  but I am not certain.

Yes. They are plentiful. A number of the teeth that I collected from the Meg Ledges are chubs. See here:

My thought is a chub because of it looks like cusps are still there. Just my thought.
