Shark or dinosaur teeth?

[Misnomer]

Hi guys I found these in an old pail of rocks my grandpa had, dinosaur or shark teeth? Thanks for your help.

Hold the phone. The center one. Has it been ground off on the base there? These are not teeth, by the way.

Hi yes it has been ground down. I’m curious now, what are they?

Just rocks, but the one has certainly been ground down.

Can you show a close shot of the ground down one, please. I'm also curious.

Thanks. I wasn't too clear in my request. Need close up of the ground off part. No detail of that is apparent in your pic.

Bits of flint or chert?
