Carbon dating the iceman

Imagine going for a hike in the mountains and finding a 5,000-year-old body frozen in a block of ice!

When a sample of his lung tissue was radiocarbon dated in the 1980s, the date was given as 3830 ± 100 B. (Before Present, a time scale used in radiocarbon dating.) However, the paper’s authors surmise there was an error, and the radiocarbon date was recorded as 3830 ± 100 B. This error was repeated in subsequent studies, pushing the Chinchorro mummy’s age back about 4,000 years earlier than his actual radiocarbon date.

This finding settled the controversy: Ötzi is older than the Chinchorro mummy by at least 500 years.

The Swedish furniture giant IKEA has banned old people from dating at its store in Shanghai, China.

Today he is known as the Iceman and has been nicknamed tzi for the tzal Alps where he was found. Researchers felt the answer lay in the Icemans possessions. The debate about the world’s oldest tattoos is over—they belong to Ötzi, the European Tyrolean Iceman who died and was buried beneath an Alpine glacier along the Austrian–Italian border around 3250 B. Ötzi had 61 tattoos across his body, including his left wrist, lower legs, lower back and torso.“I was surprised by the findings because in previous publications I brought attention to the tattooed Chinchorro mummy and its early date,” Krutak says.
