Girl Frozen For 500 years

Girl who was killed as an offering to the Inca gods sometime between 1450 and 1480, at approximately 11–15 years old.
Best-preserved mummy ever found, with internal organs intact, blood still present in the heart and lungs, and skin and facial features mostly unscathed. No special effort had been made to preserve her and 500 years later still looked like sleeping children.
