Found these bone like fossils at Topsail Island NC

[SerratedTeeth]

So we recently had a family vacation to Topsail Island NC. We found lots of teeth, 2 small megs, and several larger bones (as well as my first bitten bone). I honestly have no idea what these might be and was hoping someone could tell me! They are all generally the same shape and size (about 1 inch long), and they are very thin.

Might be worn fossil sawfish teeth.-

Probably Anoxypristis.

Three of them look like they may be partial sawfish rostrals; the third one from the top on the first pic is a bone frag.
