Isotope and infrared data from five Belgian Gallo-Roman cemeteries.

The dataset includes infrared, carbon, and oxygen isotope data from 322 cremated bones across five Belgian Gallo-Roman cemeteries. Three different skeletal elements—cranium, diaphyses of upper/lower limb long bones, and ribs—were sampled from each selected individual. However, due to extensive fragmentation in the Belgian cremated collections, the sampling location varied. In some cases, rib and cranial bones were too fragmented to sample. These data were used to assess variability in burning conditions across the five Gallo-Roman cemeteries.
