The Chinchorro mummies are mummified remains of individuals from the South American Chinchorro culture, found in what is now northern Chile. They are the oldest examples of artificially mummified human remains, becoming popular by up to two thousand years before the Egyptian mummies. While the earliest mummy that has been found in Egypt dated around 3000 BC, the oldest anthropogenically modified Chinchorro mummy dates from around 5050 BC.
The oldest naturally mummified mummy recovered from the Atacama Desert is dated around 7020 BC.
Shell midden and bone chemistry suggest that 90% of the people's diet was seafood. Many ancient cultures of fisherfolk existed, tucked away in the arid river valleys of the Andes, but the Chinchorro made themselves unique by their dedicated preservation of the dead.
While many cultures throughout the world have sought to focus on preserving the dead elite, the Chinchorro tradition performed mummification on all members of their society, making them archaeologically significant. The decision of egalitarian preservation is proven in the mummification of the often burdensome members of society (meaning those who could not contribute to the welfare of others; the elderly, children, infants and miscarried fetuses). It is often the case that children and babies received the most elaborate mummification treatments.
29% of the Chinchorro mummies found thus far were results of the natural mummification process. The earliest such mummy dates to 7020 BC, and is known as 'Acha man'.
The artificial mummies of Chinchorro are believed to have first appeared around 5000 BC and reached a peak around 3000 BC. Often Chinchorro mummies were elaborately prepared by removing the internal organs and replacing them with vegetable fibers or animal hair. In some cases an embalmer would remove the skin and flesh from the dead body and replace them with clay. Radiocarbon dating reveals that the oldest discovered anthropogenically modified Chinchorro mummy was that of a child from a site in the Camarones Valley, about 60 miles (97 km) south of Arica in Chile and dates from around 5050 BC. The mummies continued to be made until about 1800 BC, making them contemporary with Las Vegas culture and Valdivia culture in Ecuador and the Norte Chico civilization in Peru.
