Maybe, I don’t want to strain my brain here, it was something made as an ornament, to be worn like a necklace and was only made by the person who made this one. In other words something someone made only one of and wasn’t a useful object(except as jewelry so no other tribes thought to make one like it. Some scientists have brains like mush. If you’ve never seen another one in 30 years of digging perhaps that is because there are no others.
