A different type of time capsule was found washed up on a Cape Cod shore Wednesday.

Marconi Beach in Wellfleet was evacuated after a military projectile, presumed to have originated during World War II, was found on shore by a fisherman, the Cape Cod Times reports.

The Massachusetts State Police bomb squad detonated the device Wednesday afternoon after it was identified by police and fire officials as an explosive.

Sgt. Jerry Galizio of the bomb squad told the Cape Cod Times that the ordnance may have come from anywhere on the Cape and the Islands, since parts of the area were once used as military practice fields.

According to Galizio, the color of the smoke indicated that the projectile was live when it was detonated.
