An ordinary construction project uncovers an extraordinary archaeological discovery. Imagine you're watching a backhoe dig up the ground for a construction project when a round object rolls down a pile of dirt and stops at your feet. You pick it up, brush off some dirt, and realize you're holding a skull! Suddenly the construction site turned into an archaeological dig. Scientists excavated more bones and realized that they had located a long-lost cemetery for enslaved people from the 1700s.
