Tomb Detectives: Bog Bodies
Tollund Man is perhaps the world's most famous bog body. His mummified remains date back more than 2,500 years. Using technology, including x-rays and CAT scans, an archaeologist tries to determine exactly how he died.
Body parts are unearthed in a bog in Ireland. Through radio carbon dating, scientists estimate the death to be around 300 B.C., during the Iron Age.
