Help - Ancient Shark Tooth Identification

[Kelleighoo]

Hi, I have been combing the beaches of Topsail Island for years and this is the first trip that turned up multiple large finds. Usually my biggest find is the size of a nickel. This year I found over ten that I consider noteworthy…which is strange in itself. But I am having a lot of trouble identifying one in particular. I have attached a few pictures of the tooth in question here. Any help would be greatly appreciated. 
 

Usually my finds are very common…tiger, sand tiger, great white, bull, etc. but for some reason, this year turned up many ancient and worn pieces. Any opinions on why so many turned up this year vs. previous years would be appreciated too. I can only assume that maybe the coast was recently dredged, and this made older pieces become beached (??)

Probably too worn to ID positively. Maybe some locals will weigh in.

I think they went through another round of beach nourishment this year. A lot of beaches in North Carolina are currently undergoing beach nourishment. 
 

This tooth has too much wear for positive ID. About half of the root is gone, along with most of the enamel. But based on the size, and guessing the age is Oligocene ( a lot of Topsail fossils are Oligocene), it could be Otodus angustidens.

Yeah super worn unfortunately - but it gives off a lot of Otodus vibes to me!

I agree with Eric, it could be Otodus angustidens.

Neat find, very water worn, but I would agree with a possible Otodus angusitens. As my good chum @Meganeura has suggested, it really gives off those vibes .
