I'm not sure the RAT was used anywhere near this "flake"
I don't doubt there is a non-biological explanation for the odd look of this flake but I'm not a geologist so I have no idea what that is. I know the human eye also sees what it wants to see. For example, I can "see" a face in this thing too. :-) Just because it looks biological doesn't mean it is. (That doesn't mean it isn't either!)
