Macro- and microscopical inspection, and imaging methods (such as X-raying) permit the establishment of the indispensable biological baseline data and scientific information for the pursuit of questions relating to the diverse aspects of daily life. To answer these, molecular biological methods are applied.
The analysis of stable carbon and nitrogen isotopes in bone collagen, and stable carbon and oxygen isotopes in the bone apatite permit an in-depth reconstruction of palaeoecosystems and their diachronic change.
Especially in comparison with archaeozoological finds, dietary habits and subsistence economies are unraveled. Beyond aspects of palaeodiet, important ecological parameters (such as microclimate, clearing of landscapes, average temperature, spectrum of flora and fauna), and the proportion of immigrants can be reconstructed.
