Hello, I found your website and wondered if someone could tell me if this rock/artif
act I found is a petroglyph …it's about 3 1/2"diamet er.
[Update 1: I would add that the "design" is pecked into the rock surface and the color delineation is from the difference in surface levels (ie the "outside" of the rock is the orange-y color and what shows up as more gray is the pecked out area.]
[Update 2: One photo is included here which shows the back of the rock. I found this on a hilltop in central Texas, in the Hill Country. There are many areas of flint etc around and we have found multiple points also. Below this hilltop and down aways is a creek with springs so we know Indians were present for a long time. I also just read of articles on bird stones, and as soon as I saw one of your photographs, I thought of one that I'd picked up a couple of weeks ago as a curiosity thinking that it reminded me of a bird so much, and kept it. I was astounded to read your information. I'll take a picture of it also as soon as I can and show it to see if it might be a bird stone.]
[Update 3 - One last picture (in higher mag if you click). I have to say this is looking more and more like an artifact - PWAX]
