When Kaleb Kidd of La Crosse, Wisconsin was out chasing squirrels, he got to be the hero of the dream every little boy has when he found a 30,000-year-old tooth from an extinct woolly mammoth. At first it looked like a rock, but on close inspection, Kaleb's grandfather suspected that it was a fossil. They took it to the Mississippi Valley Archaeology Center and were told that it was indeed the tooth of a woolly mammoth. Kaleb was very excited and the tooth is currently on display at the Satori Arts Gallery.
