Over the past centuries, remains of many hundreds of people men, women, and children have come to light during peat cutting activities in northwestern Europe, especially in Ireland, Great Britain, the Netherlands, northern Germany, and Denmark. These are the "bog bodies." The individual bog bodies show a great degree of variation in their state of preservation, from skeletons, to well-preserved complete bodies, to isolated heads and limbs. They range in date from 8000 B.C. to the early medieval period.
