Radiocarbon dating as far back as 5050 B.C. makes them the world's oldest mummies.

However, after staying remarkably well-preserved for millennia, in the past decade many of the Chinchorro mummies have begun to degrade rapidly. To discover the cause and a way to stop the deterioration, Chilean preservationists turned to a Harvard University scientist with a record of solving mysteries around threatened cultural artifacts.

Nearly 120 Chinchorro mummies are housed in the collection of the University of Tarapaca's archaeological museum in Arica, Chile. That is where scientists saw that the mummies were starting to degrade at an alarming rate. In some cases, specimens were turning into black ooze.

Preparing the mummies "was a complicated process that took time --and amazing knowledge," says Marcela Sepulveda, professor of archaeology In the Department of Anthropology and the Archeometrlc Analysis and Research Laboratories at the University of Tarapaca
