Construction workers digging a foundation for a new home in Great Barrington in January turned up an unusual find that experts say could date back more than a century — a human skull.

Days later, archeologists found even more remains at the site.

According to the Great Barrington police, crews from Hewins Construction were digging at the location off Park Street on Jan. 28, when they discovered the skull.

The construction company contacted police, who then brought in the chief medical examiner’s office, and state troopers assigned to the office of District Attorney David F. Capeless.

Great Barrington police said in a Facebook post Wednesday that after the scene was documented and cleared, officers took possession of the skull.

James T. Pokines, a forensic anthropologist, later determined that the skull was likely 100 years old, and belonged to a woman of African descent.

A day after the skull was found, Pokines, at the behest of the state medical examiner’s office, went to the construction site with tools in hand, and conducted more digging.

During the excavation, Pokine found a separate set of skeletal remains that he believed belonged to a male teenager, police said.
