On a school trip to Grand Staircase-Escalante National Monument in Utah in 2009, 17-year-old Kevin Terris made an amazing discovery. While exploring the national monument with his class, he noticed a jutting rock that turned out to be a fossil of a baby duck-billed dinosaur. While digging at the site, scientists finally discovered that the duck-billed dinosaur had died before the crest on its head had even formed. The fossil is on display at the Alf Museum in California.
