Abstract

In this paper, we examine the exchange of crops and livestock through the application of strontium (87Sr/86Sr) isotope analysis on cereal grains and faunal tooth enamel from the regional center of Uppåkra and three nearby settlements in Scania, southern Sweden, dating to the first millennium AD. Around a third of the fauna have non-local 87Sr/86Sr values, indicating the import of livestock from several different regions. After cleaning, almost all of the cereal grains have non-local 87Sr/86Sr values, which is surprising given the nearby abundance of fertile agricultural soils. We therefore suggest considering non-locally grown crops to be those whose... (More)

In this paper, we examine the exchange of crops and livestock through the application of strontium (87Sr/86Sr) isotope analysis on cereal grains and faunal tooth enamel from the regional center of Uppåkra and three nearby settlements in Scania, southern Sweden, dating to the first millennium AD. Around a third of the fauna have non-local 87Sr/86Sr values, indicating the import of livestock from several different regions. After cleaning, almost all of the cereal grains have non-local 87Sr/86Sr values, which is surprising given the nearby abundance of fertile agricultural soils. We therefore suggest considering non-locally grown crops to be those whose 87Sr/86Sr values fall outside the normal distribution; if this approach is used, around 20% of the analyzed crop samples are interpreted as having grown non-locally. This study demonstrates the potential of combining strontium isotopic data of archaeobotanical and zooarchaeological material for gaining insights into the movement of agricultural products in prehistory.
