Archaeologists Excavating A Bog In Sweden Just Came Across A 5,000-Year-Old Dog Burial

The dog's remains were found alongside a bone dagger, suggesting the creature was buried ceremonially.

Ahead of the development of a high-speed railway near Gerstaberg, Sweden, archaeologists recently excavated a bog that was once a lake. During their dig, they came across two surprising artifacts: a bone dagger and the remains of a dog that was seemingly sunk into the water intentionally.

The two objects, which are roughly 5,000 years old, offer a tantalizing glimpse at funerary practices during the Stone Age. What’s more, archaeologists believe that prehistoric people once had a thriving lakeside settlement nearby.

The 5,000-Year-Old Dog And The Bone Dagger Found In A Bog

According to a press release from Arkeologerna, a Swedish archaeological consulting firm, the dog and the dagger were found near Gerstaberg during excavations ahead of the Ostlänken railway development project.

While digging in the bog — which was a deep lake 5,000 years ago during the Stone Age — the archaeologists came across the remains of a dog with a crushed skull buried alongside a bone dagger. The dagger, which is roughly 10 inches long and made of elk or red deer bone, was placed “in direct connection” to the paws of the dog, suggesting that they were deposited together.

“Finding an intact dog from this period is very rare, and the fact that it was deposited together with a bone dagger is almost unique,” archaeologist and Arkeologerna project manager Linus Hagberg remarked.

Dogs Crushed Skull

Though archaeologists are hoping to conduct further tests to learn more about the dog, they’ve so far determined that it was a “large and powerful male” with a shoulder height of roughly 20 inches. The dog was around three to six years old when it died and had seemingly lived an active life.

“It had been deliberately lowered to a depth of [roughly five feet] and about [100 to 130 feet] out into the lake. The use of dogs in ritual practices during this period is a known phenomenon,” Hagberg explained. He added that radiocarbon dating, isotope analysis, and DNA analysis of the dog’s remains will also tell researchers about “when the dog lived, its age, and what it ate.”

This, in turn, can tell archaeologists more about the people who lived alongside the dog. But archaeologists have already uncovered a few clues about the Stone Age settlement that once existed on the edge of the lake.

A Once Thriving Lakeside Settlement From The Stone Age

In addition to the dog remains and the bone dagger, archaeologists also found evidence of a lakeside settlement that existed at the site from roughly 3300 B.C.E. to 2600 B.C.E.

Specifically, they found “well-preserved wood material,” including stakes and posts that might have once formed wooden piers along the shore. They also uncovered “deliberately placed stones,” which could have served as anchors and net weights, as well as a prehistoric fish trap made of interwoven branches.

“Adjacent to the fish trap are trampled areas where it is possible to see that people have stood and moved about on the lakebed,” Hagberg remarked. “These appear as patches in the mud. Perhaps they were checking their traps.”

Though many questions about the dog burial in the Swedish bog remain, it’s far from the first time that archaeologists have found evidence of prehistoric humans burying canines. In recent years, archaeologists have also uncovered the 8,400-year-old burial of a man with a dog in Sweden, the 2,700-year-old ritual burial of four dogs in Turkey, and the 1,100-year-old burial of a Viking woman who was seemingly laid to rest with her dog in Norway.

For now, archaeologists are still puzzling over why the dog was sunk in the lake with the bone dagger in Sweden. And though exact answers remain elusive, further testing may offer exciting insights into the Stone Age community where the dog once lived.
