dissolved rather than preserved. Scientists conducted an isotope analysis of the element strontium to measure the quantities down to the minute to get an accurate idea of where he may have traveled before his death. They took samples from his femur and hair to compare. They were only able to measure up to a year because of his hairs being short. The results contained only small differences in strontium isotope proportions, suggesting that he spent his final year in Denmark, and that he may have moved at least in his last six months. Examinations and X-rays showed that the man's head was undamaged, and his heart, lungs and liver were well preserved. The Silkeborg Museum estimated his age as approximately 40 years and height at , a relatively short stature even for the time. It is likely that the body had shrunk in the bog. On the initial autopsy report in 1950, doctors concluded that Tollund Man died by hanging rather than strangulation. The rope left visible furrows in the skin beneath his chin and at the sides of his neck. There was no mark, however, at the back of the neck where the knot of the noose would have been located. After a re-examination in 2002, forensic scientists found further evidence to support these initial findings. Although the cervical vertebrae were undamaged (these vertebrae are often damaged as a result of hanging), radiography showed that the tongue was distended—an indication of death by hanging. The stomach and intestines were examined and tests carried out on their contents. Scientists identified the man's last meal as porridge or gruel made from grains and seeds, both cultivated and wild. Approximately 40 kinds of seeds were identified, but the porridge was primarily composed of four types: barley, flax, false flax (Camelina sativa), and knotgrass. From the stage of digestion it was concluded that the man had eaten 12 to 24 hours prior to his death. Porridges were common for people of this time. Because neither meat nor fresh fruit was found in the last meal, it is suggested that the meal was eaten in winter or early spring, when these items were not available. Both feet and the right thumb, being well conserved by the peat, were also preserved in formalin for later examination. In 1976, the Danish police made a fingerprint analysis, making Tollund Man's thumbprint one of the oldest prints on
