Task 3 - Animal mobility through strontium and oxygen stable isotopes
Coordinator: Silvia Valenzuela-Lamas
The aim of this task is to determine the geographical provenance and mobility of livestock (cattle and sheep/goats) in the regions and time span considered (ancient Lusitania in
Roman times) by means of the evidence provided by isotopic chemistry (strontium and oxygen stable isotopes).
The objectives are:
- to establish the catchment areas of cattle and sheep/goat slaughtered at major sites in the studied territories and chronological periods b y means of strontium and oxygen stable isotopes.
- to determine whether seasonal movements of livestock (transhumance) existed in Roman times in the studied territories by means of sequential strontium and oxygen stable isotopes.
- to create the necessary isotopic maps needed in order to relate the archaeological results with geographical locations.
