LIMA, PERU—Two mummies, an adult and an infant, were found by archaeologists inside a tomb at Huaca Pucllana, which dates to the Wari civilization, more than 1,000 years ago. Both bodies were wrapped in ceremonial fabric, and the child was likely sacrificed on behalf of the adult. The tomb also contained 10 complete artifacts, including jars, and remains of guinea pigs, which were likely also sacrificed.
