Hello, I'm new to the forum. I have this interesting rock. It is about 7 inches wide, 7 inches tall, 3 to maybe 4 inches deep. I believe it was found a few miles from an extinct volcano, so I'm guessing it is at least partly volcanic. But parts of it look sorta plantlike, or perhaps like teeth. (The tan, tapering rods) and the nearly-lavender part that drapes around the knobby, deeply textured parts looks skin-like. So I'm curious: what is it? I will try to upload photos.
