Native American artifacts or rock?

[diggergirl]

I live in Connecticut and found these artifacts (or rocks). I live in an area frequented by the Tunxis tribe. I cleaned them off with water and a toothbrush. The last one is painted on one side and appears to have a person with a hunchback playing a flute to a bird? It’s only painted on one side and I don’t want to keep cleaning it because I don’t want to rub it off.

Any information would be so appreciated.
Thank you!

Natural cobble. It shows no pecking or work by man. Welcome to T-net.

Welcome! Agree they are just rocks. Keep looking and you're sure to find something soon.

Mother Nature can do some amazing things! Down here we call those river or creek rocks. I sometimes save some of the nicer ones. Did man pick one up and use it? Probably so, but he did not make it.

a leaf that fell on that rock and disintegrated over time could leave such a stain on your rock.
