Lady of Cao
It took 15 years to unearth a Peruvian mummy that was later dubbed "Lady of Cao." She had been buried in a bundle of cloth. Researchers were able to determine that the woman's remains were dated back to the year 400. Because of the ornate manner in which she was wrapped, as well as the fact that women were rarely embalmed like this, she was believed to have been an aristocrat.
