Trace element analysis has become a promising approach to discovering ancient life-styles and subsistence for archaeologists and physical anthropologists. In Central Europe, however, human bodily remains consist of cremations for a period of approximately 2,000 years. Data on the elemental composition of cremations are scarce and there is a lack of information on high temperature artifacts in cremated bones. This article presents the results of an experimental approach aimed at the assessment of in vivo elemental composition from bones which have been incinerated prior to inhumation. It was concluded that in the case of cremated material, the trace element spectrum available for palaeodietary reconstruction is limited. For strontium to calcium ratios however, which are most widely used for palaeodietary reconstruction, it is shown that an estimation of in vivo ratios from incinerated specimens is possible by regression analysis.
