Abstract

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 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.

公元一千年斯堪的纳维亚铁器时代的农产品运动:瑞典南部考古作物和动物的87Sr/86Sr值

摘要:本文通过对来自瑞典南部乌普克拉地区中心和斯堪尼亚附近三个定居点的谷物和动物牙釉质进行锶(87Sr/86Sr)同位素分析，研究了公元一千年以来作物和牲畜的交换。大约三分之一的动物群具有非本地的87Sr/86Sr值，表明从几个不同地区进口牲畜。清洗后，几乎所有谷物都具有非本地87Sr/86Sr值，考虑到附近丰富的肥沃农业土壤，这是令人惊讶的。因此，我们建议考虑非本地种植的作物，其87Sr/86Sr值落在正态分布之外;如果使用这种方法，大约20%的分析作物样本被解释为非本地生长。这项研究表明，结合考古植物和动物考古材料的锶同位素数据，可以深入了解史前农产品的运动。图形抽象
