Excarnation

In archaeology and anthropology, the term excarnation (also known as defleshing) refers to the practice of removing the flesh and organs of the dead before burial. Excarnation may be achieved through natural means, such as leaving a dead body exposed to the elements or for animals to scavenge; or by butchering the corpse by hand. Following excarnation, some societies retrieved the bones for burial. Excarnation has been practiced throughout the world for hundreds of thousands of years. The earliest archaeological evidence of excarnation is from the Awash River Valley in Ethiopia, 160,000 years ago. Examples of excarnation include "sky burials" in parts of Asia, the Zoroastrian "Tower of Silence", and Native American "tree burials". Excarnation is practiced for a variety of spiritual and practical reasons, including the Tibetian spiritual belief that excarnation is the most generous form of burial and the Comanche practical concern that in the winter the ground is too hard for an underground burial. Excarnation sites are identifiable in the archaeological record by a concentration of smaller bones (like fingers or toes), which would be the bones that would be the easiest to fall off the body, and that would not be noticed by practitioners of excarnation. From the pattern of marks on some human bones at prehistoric sites, researchers have inferred that members of the community removed the flesh from the bones as part of its burial practices. Since metatarsals, finger bones and toe bones are very small, they would easily fall through gaps in a woven structure or roll off the side during this removal. Thus a site where only small bones are found is suggestive of ritual excarnation. Archaeologists seeking to study the practice of ritual excarnation in the archeological record must differentiate between the removal of flesh as a burial practice, and as a precursor to cannibalism. When human bones exhibiting signs of flesh removal are discovered in the fossil record, a variety of criteria can be used to distinguish between the two.
