Carbon dating the iceman
Through CT analysis and use-wear analysis, researchers determined that Otzi did not have access to lots of chert, and therefore, most of his tools were worn down and resharpened over time instead of being replaced."Evidently Ötzi had not had any access to chert for quite some time, which must have been problematic during his last hectic days, preventing him from repairing and integrating his weapons, in particular his arrows.The species, which likely grew in the valley below Otzi's final resting place, only blooms between March and June.Found on the remains of Otzi's clothing were two pieces of birch fungus threaded onto narrow strips of hide.Freshly modified blade tools without any wear suggest planned work which he never carried out, possibly prevented by the events which made him return to the mountains where he was killed by a Southern Alpine archer," the study notes.The style and materials used to make his tools come from at least three different areas in the Southalpine region and are reflective of northern Italian and Swiss Horgen culture, which shows he interacted with other transalpine people.The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.
Only after archaeologists had a chance to examine Otzi, so-named for the mountain range where he was discovered, did the stunning truth of his age come to light.
A study of the stomach in 2011 showed that two hours before death, he ate another meal of ibex, a wild goat and yet more grains.
Another study conducted in 2018 revealed he had a high proportion of fat in his diet that was supplemented with fresh and dried wild meat, cereals and toxic bracken (ferns).
Using radiocarbon dating, scientists determined that he had perished in the Alps an astounding 5,300 years earlier.
The preservation from the ice pocket he fell into was so thorough that his brain, internal organs, penis, pubic hair and one of his eyeballs were all completely intact.
