Hello, new here. I found this off the side of the highway 95 near the Nevada/Oregon state line. I’m thinking it’s petrified wood, but I don’t know enough to be certain. Your help and opinions would be greatly appreciated!
It’s pretty heavy and hard, smooth on 5 sides and rougher on one.
A strange thing, could just be environmental, the “rough” side of the rock has a strange smell, kinda of like old cooking oil.
photos of “sides” attached. I’ll add photos of top bottom and a few others in comments.
