I'm thinking this is some sort of seed. But it's not any of the ones I've had in the past.

What throws me on this one is it's very assymmetry. Part of this isn't just broken off. It is totally asymmetrical. And the funny thing is, I have identified similar ones in Asia and other places but not in North Carolina.

That's it for now. We'll see if I find some others. But if you know what these are, will you please let me know?
