An Interesting Find

Awhile back, I found this small black pebble in our back yard. I didn’t think too much about it as this black stone is fairly common in our yard.

However, when I looked closely at it, I saw that it had these lines on it.

The lines are in a triangular, diamond shape and are evenly spaced. They radiate out from the center of the depression on the pebble.

Are these man-made or a quirk of natural processes? I have no idea, but it’s really interesting to me.
