A Dentist Found a Jawbone in a Floor Tile
Recently, a man visiting his parents’ newly renovated home recognized an eerily familiar white curve in their tile floor. To the man, a dentist, it looked just like a jawbone. He could even count the teeth—one, two, three, four, five, at least. They seemed much like the ones he stares at all day at work.
The jawbone appeared at once very humanlike and very old, and the dentist took his suspicions to Reddit. Could it be that his parents’ floor tile contains a rare human fossil? Quite possibly. It’s “clearly hominin,” John Hawks, a paleoanthropologist at the University of Wisconsin at Madison who also blogged about the discovery, told me in an email. (Hominin refers to a group including modern humans, archaic humans such as Neanderthals, and all of their ancestors.) It is too soon to say exactly how old the jawbone is or exactly which hominin it belonged to, but signs point to something—or someone—far older than modern humans. “We can see that it is thick and with large teeth,” Amélie Vialet, a paleoanthropologist at the Muséum National d'Histoire Naturelle in Paris, wrote in an excited email to me about the jawbone. “That’s archaic!”
An international team of researchers, including Vialet, is now in contact with the dentist to study the floor tile. (I’m not naming him for privacy reasons.) This thin slice of jawbone has a story to tell—about a life lived long ago, in a world very different from ours. It is in fragments of hominin bone like this one that we begin to understand our past as humans.
