A while back (1894 - okay, quite a while back), archeologists found this cool wooden column in a peat bog in the Ural mountains, and they saw immediately that it was old. I mean, really old. They eventually stopped standing around saying, "That looks really old", and did some science on it to determine it was 9,500 years old.
New sciencey stuff actually shows that it's much older. It's really 11,000 years old!
