ROSKILDE, DENMARK—A submerged Stone Age settlement and a boat were discovered off the coast of Denmark’s Askø Island. The vessel shows signs of repairs. “It split 6,500 years ago and they tried to fix the crack by putting a bark strip over it and drilling holes on both sides of it. The most exciting thing is that there is sealing mass in the holes. We have found sealing mass before—such as bits of resin that children have chewed on and made flexible,” Jørgen Dencker of the Viking Ship Museum told The Copenhagen Post. Dencker and his team will look for additional artifacts made of organic materials in the submerged Stone Age settlement.
