A 7-year-old boy, Arthur, was exploring the coast of Cornwall, United Kingdom, when he found what he initially thought was a shark tooth, according to People. Instead, the discovery turned out to be that of a human’s, which eventually led archaeologists to a burial site. The National Trust said the site could potentially be connected to a nearly 300-year-old shipwreck.
He showed the collection of the teeth to a National Trust volunteer, Ken Wallace, who is also a retired dentist. Wallace immediately recognized them as human teeth, while a police inquiry later confirmed that the find was archaeological. This led Jim Parry, a National Trust archaeologist, to investigate the area.
