There are now several books on the Ice Man that you should be able to find in your school or public library. The books are well illustrated and will tell you all about his discovery and conservation. The Ice Man died approximately 5200 years ago. At death he was between 40 and 50 years old and suffered from a number of medical conditions. He turned into a mummy accidentally almost immediately by the freezing weather conditions that turned him into the Ice Man.
Scientists believe that tzi was caught in a heavy snowfall, fell asleep, and froze to death.
Scientists have concluded this because there were no signs of predator attacks. They believe that the body must have been covered with snow almost immediately. The first clues to how old the Ice Man was came from many of the tools and objects found with him. The stone ax and stone knife found with him were similar to other stone tools found elsewhere and which are thousands of years old. A more exact date was given using a scientific test called Carbon 14 dating that can tell the age of almost anything that ever lived - dead animals, dead people, plants, or things like cloth, which comes from living matter.
