Phillip Stoll, 9-years-old, a Michigan boy stumbled upon the treasure of a lifetime! He was walking along a local creek when he discovered a MASTODON TOOTH! He told CNN, "I was walking down at the creek last summer. I felt something that I stepped on so I picked it up and everybody in the neighborhood thought it was pretty cool."
After taking the object home and washing it off, Phillip suspected that it was a very large tooth. Michigan State herpetologist, James Harding, confirmed that the object was indeed a Mastodons tooth, aged at approximately 10,000 years-old!
