A piece of history has been found thanks to a boy tripping on a rare, 1.2-million-year-old animal fossil. In November 2016, Jude Sparks, now 10, was on an outing with his family near their New Mexico home, when he tripped over what he thought was a cow bone. Now, researchers at New Mexico State University preserving this discovery, which was identified as an ancient elephant-like animal. Kyle Sparks, father of Jude, said he let his son decide what to do with the fossil. So Jude reached out to Peter Houde, a professor at New Mexico State University who had experience with the same type of fossil in the past. The next day, Houde came out to see the fossil for himself. Houde told ABC News that he was quite excited about the find. It was fortunate that the family didn't try to dig up the fossil because that could destroy the specimen; they did the right thing by calling someone who would know what to do. "It's great for the community because now everybody can appreciate it," he added. Houde and his fellow faculty members dug up the fossil in late May. They hope to return to the site with geologists for an additional search as there could be more fossils near the site. Jude and his family had been invited by the researchers to see the fossil being preserved at the university.
