This is not a cinnamon bun. It's actually a 160 million year old fossil snail shell from Madagascar, roughly the size of a large fist (or cinnamon bun). I don't think it's particularly rare or valuable; I picked it up because I liked its shape.
Would still try eating.
@11011110 How do you know the age of the fossil?
@blitz It was on a card included with the fossil when I bought it. (How do I know the reliability of the date? I don't.)
