Found in Green Mill Run in Greenville, NC. Anyone have any ideas?

I feel like the larger is a cetacean, turtle, or *possibly* mosasaur? The little one I really have no clue.

You could put the little one under stereo microscope and photo certain sections, that way we could see what we don`t see, and you could also.

Smaller one maybe base of a mosasaur tooth with the tooth itself broken off. This is a guess, not an ID.

  Can't be sure that I see bone structure on the big piece. If you can take a sharp close up of a broken portion it would be good.

Wouldn’t that be cool, I figured it may be too worn to ID for sure. Here are some up close pics of the larger piece, sure seems like bone to me, though there’s always the chance of it being a super tricky rock.

If I had a microscope I would, but I don’t own one unfortunately
