Help With Shark Tooth Id - South Carolina

[bkstyl]

Hello, We returned from vacation (North Myrtle Beach, SC) a few weeks ago and I've been working to ID some of our beach finds. I've had some issues with getting a positive ID on this one (my best guess is Hemipristis Serra or possibly a Dusky). Any help you can provide would be greatly appreciated.

Thank you,

Will

looks like a hemi to me

Hmm i would definitely say it is a lower tooth of a requiem( carcharhinus) shark, not a hemi. Its root and serration pattern/size do not match hemipristis teeth. When all serrations are similar in size and not that coarse, it is usually requiem shark teeth.

Agreed.

Can you take a picture from a different angle? One side is hidden. Thanks

The tooth is definitely not Hemipristis. I will agree that it is Carcharhinus ( Gray sharks a.k.a. requiem sharks) and I would say an upper. As far as a certain species of Carcharhinus, that may be hard to assign as the tooth is not complete and so many of the Carcharhinus species teeth are so very similar. If I were to try to assign a species, I would guess either C. obscurus (Dusky) or C. perezii ( Caribbean Reef)

Thanks for all of the feed back.

Here are a few additional images of the tooth. Hope this help.
