Ötzi (German pronunciation: [ˈœtsi]; also called Ötzi the Iceman, the Similaun Man, the Man from Hauslabjoch, Homo tyrolensis, and the Hauslabjoch mummy) is a well-preserved natural mummy of a man who lived around 3,300 BCE, more precisely between 3359 and 3105 BCE, with a 66% chance that he died between 3239 and 3105 BCE. The mummy was found in September 1991 in the Ötztal Alps, hence the nickname "Ötzi", near the Similaun mountain and Hauslabjoch on the border between Austria and Italy. He is Europe's oldest known natural human mummy, and has offered an unprecedented view of Chalcolithic Europeans.
