Hair analysis was used to examine his diet from several months before.
The body was semi-officially extracted on 22 September and officially salvaged the following day.
It was transported to the office of the medical examiner in Innsbruck, together with other objects found.
One of the carvings shows an archer being poised to fire an arrow towards the back of an unarmed man who is running away.
The corpse has been extensively examined, measured, X-rayed, and dated.
At the Treaty of Saint-Germain-en-Laye of 1919, the border between North and South Tyrol was defined as the watershed of the rivers Inn and Etsch.
However, near Tisenjoch the (now withdrawn) glacier complicated establishing the watershed at the time and the border was established too far north.
Analysis of the contents revealed the partly digested remains of ibex meat, confirmed by DNA analysis, suggesting he had a meal less than two hours before his death. High levels of both copper particles and arsenic were found in Ötzi's hair.
This, along with Ötzi's copper axe blade, which is 99.7% pure copper, has led scientists to speculate that Ötzi was involved in copper smelting.
By examining the proportions of Ötzi's tibia, femur and pelvis, Christopher Ruff has determined that Ötzi's lifestyle included long walks over hilly terrain.
