Ṣìgìdì (òkú): Ìyàtọ̀ láàrin àwọn àtúnyẹ̀wò

'''Ṣìgìdì''' is a body, human or animal, whose [[human skin|skin]] and [[organs]] have been preserved by either intentional or [[incidental]] exposure to [[chemical]]s, extreme coldness (ice mummies), very low [[humidity]], or lack of air when bodies are submerged in [[bog]]s, so that the recovered body will not decay further if kept in cool and dry conditions. Some authorities restrict the use of the term to bodies deliberately [[enbalming|embalmed]] with chemicals, but the use of the word to cover accidentally desiccated bodies goes back at least to the 1730s. The oldest known naturally mummified human corpse is a [[decapitated]] head dated as 6,000 years old, found in 1936.<ref>{{cite web|url=http://www.archaeometry.org/paleoamerican.htm|title=Andean Head Dated 6,000 Years Old|publisher=archaeometry.org|accessdate=2009-02-20}}
