LAMBAYEQUE, PERU—The 600-year-old tomb of a Chimú noblewoman has been uncovered at the Saltur archaeological complex in northern Peru. She had been buried with the remains of fish and birds, and several intact pottery vessels. Estimated to have been around 30 years old at the time of her death, the woman had been buried with her knees bent. Other tombs at the site have been ravaged by looters.
