An ancient comb carved from a chunk of human skull has left researchers in London scratching their heads about whether or not it was actually used to style hair thousands of years ago. 

Archaeologists first discovered the item at Bar Hill, a village in Cambridgeshire, England, during a three-year dig that ended in 2018. The artifact, which dates to the Iron Age (750 B.C. to A.D. 43) and measures approximately 2 inches (5 centimeters) long, contains nearly a dozen carved teeth and was part of the collection at the Museum of London Archaeology (MOLA).

Dubbed the Bar Hill Comb, the piece is one of 280,000 artifacts from the museum included in an ongoing analysis. Researchers can only theorize the true purpose of the item. There was no evidence showing wear on the comb's teeth, and a hole drilled into the top suggested it may have been worn as an amulet rather than used as a tool to style hair. 

Despite its unknown purpose, the item offers a glimpse of how Iron Age people may have had different uses for human remains, the researchers said. These purposes may have included rituals.

"The Bar Hill Comb may have been a highly symbolic and powerful object for members of the local community," Michael Marshall (opens in new tab), a prehistoric and Roman finds specialist at MOLA who led the project, said in a statement. "It is possible it was carved from the skull of an important member of Iron Age society, whose presence was in some way preserved and commemorated through their bones."

This isn't the first time an artifact reworked from human remains has been discovered in the region. Previous digs have revealed tools that were crafted from human leg and arm bones and used to clean animal skins, according to the statement. 

Two similar pieces of repurposed human skull from Cambridgeshire also resemble combs. One, featuring carved teeth, was unearthed in the 1970s, and the other, with only incised lines, was found in the early 2000s. Marshall thinks that if the objects weren't intended for combing hair, the carvings were "meant to represent the natural sutures that join sections of the human skull," he said.

"It is possible this fascinating find represents a tradition carried out by Iron Age communities living solely in this area of Cambridgeshire," Marshall said. "To be able to see such hyper-local influences in groups of people living over 2,000 years ago is truly astonishing."

The Bar Hill Comb will join the Cambridgeshire Archaeology Archive, which houses artifacts unearthed across the region.
