Not a meteorite. It looks green. The most common green river rock is in the serpentine group. May I ask what state you found it in? Sometimes nehprite jade comes in that color of green, but only in a few places in the US.
If you look at it sideways it looks a little like Groot from "The Guardians of the Galaxy"
Can someone tell me why the website sometimes "turns" pictures sideways? And how to fix it? I rotated rock Groot to be properly oriented prior to posting it. If you click on it, it rotates to the orientation I intended, but in the post it's still sideways.
