Hi everyone, newbie here. I was walking through the woods along a creek in upstate New York and found this rock in the creek. I've never seen anything like it, so thought I'd show it here and see if anyone can figure out what it is. It's about 12" high. I'm thinking it may be a rock full of fossils, but I surely don't want to break it open because I don't know what I'm doing and don't want to destroy it. I've also searched on the internet for a couple hours and didn't find anything that resembles this.
