Bone?

[Wildcat1750]

Not exactly sure what type of fossil this is. Outside is grainy, inside is smooth, and the bore is narrow and thin in cross section. Beach find at North Topsail Beach, NC.
Thanks for looking!

I believe it is part of a Sting Ray barb. It is sand worn from the surf.

I think horse shoe crab tail piece.

My best guess is broken horse tooth fragment.

Thanks, CaptEsteban, gunsil, and Perico! These are all interesting possibilities... I wish I had more of it to help with the ID!
