Fantastically Preserved Viking Boat Grave and Skeletons Unearthed in Sweden Archaeologists recently unearthed two Viking burial boats in Uppsala, Sweden — one of which was exceptionally preserved and held the remains of a dog, a man and a horse. The Vikings sent a handful of their powerful elites to the afterlife in boats laden with sacrificed animals, weapons and treasure; the funeral practice dates back to the Iron Age (A.D. 550 to 800) but was used throughout the Viking age (A.D. 800 to 1050), according to a statement. These richly appointed graves have been discovered across Scandinavia. For example, archaeologists had previously found one such burial boat in Norway that had evidence of human remains and one in western Scotland that contained a slew of burial items such as an ax, a shield boss, a ringed pin, a hammer and tongs. The elites who were given such elaborate send-offs were also often buried with animals, such as stallions. These burial boats were typically built with overlapping wooden planks (called "clinker built") and had symmetrical ends, a true keel and overlapping planks joined together, said Johan Anund, the regional manager for The Archaeologists, an archeological organization working with the National Historical Museums in Sweden. Archaeologists have also found other, simpler boat structures, such as logboats, which are like a dugout wide canoe, Anand told Live Science in an email.

"We don't know much" about the man yet, Anund said. But analysis of the skeleton will reveal how old he was, how tall he was and if he had any injuries or diseases. Anund's group may even be able to figure out where the man grew up and where he lived for most of his life, Anund said. As for the animals buried with him, they could have been sacrificed to help the dead person on the "other side" but could also be there to show the man's status and rank, Anund said. It's common to find horses and dogs in such burials, but also big birds like falcons. Archaeologists also found other items on the boat such as a sword, spear, shield, an ornate comb, and leftover wood and iron nails that were likely used in its construction.
