WHAT IS IT? . .... Native American Artifacts?

[cowsaretrippy]

Previously posted this in a different thread but felt this thread / category is more suitable. ...

Found these 2 items on a farm in eastern PA.
The one was in a corn field the other by a creek
The first item I believe is a worker piece, possibly from Flint knapping or an abrader .

The 2nd peice found by the creek can easily be nothing but to me looks to unique in shape to be a natural cut rock. It sort of reminds me of a paperfootball the way it is shaped

Any ideas on what these items truly are if anything at all?
Thanks!

Edit:
BTW decided to add another photo of a mystery item I found from the same site beneath an old bridge that runs over a creek in the area .. it's the 2nd item on the right. I have no idea what type of stone it is. Possible Native American paint dish or just a random chunk of concrete?

Those look nature to me. I don’t see any alteration by man. Keep looking there’s plenty of artifacts out there waiting to be found. Good luck!

Sorry, they all look like natural rocks, not artifacts. Better luck next time.

As said by others, natural stone. No evidence of being knapped or used in any form by Native Americans.

I agree with what has already mentioned here, they look natural to me.

Maybe consider posting here as well... North American Indian Artifacts

The third picture down kinda looks like a gun flint.
