Galgedil: isotopic studies of a Viking cemetery on the Danish island of Funen, AD 800–1050

Galgedil is a Viking Age cemetery located in the northern part of the Danish island of Funen. Excavations at the site revealed 54 graves containing 59 inhumations and 2 cremation burials. Previous study of the remains to date has included light isotopes of carbon and nitrogen in collagen (10 samples) and the radiocarbon determination of the age of 8 samples. In addition, aDNA was investigated in 10 samples from the cemetery. Here we report the analysis of strontium isotopes in human tooth enamel as a signal of place of birth. Some 36 samples have been measured and non-local outliers identified. Baseline levels of strontium isotope ratios in Denmark are discussed and documented. Our study also includes an in-depth consideration of the bioarcheology of the skeletal remains in terms of demography, paleopathology, and taphonomy. The burials are evaluated in light of the available archeological, chronological, anthropological, and isotope information available.
