Ivory from early Anglo-Saxon burials in Lincolnshire – A biomolecular study

Ivory bag rings have been found in more than 70 cemeteries across southern, central, and eastern England dating to between the late-5th and 7th centuries AD. These rings are most frequently found in richly furnished female graves, and would have served as the framework for bags that hung at the waist. Debate over the source of this ivory has prevailed since the 19th century, with walrus and mammoth ivory considered as possible contenders to elephantid ivory. Recent excavations at an early Anglo-Saxon cemetery in Scremby, Lincolnshire revealed a number of elaborate female burials containing such bag rings. Using radiocarbon dating this study aimed to establish whether the rings were contemporary with the burials before seeking to identify the species of ivory through Zooarchaeology by mass spectrometry (ZooMS). Strontium analysis was also used to identify the place of residence of the elephantids at the time of tusk formation. Through a multi-methodological approach, we have established that the ivory used for the Scremby bag rings came from elephants living in an area of young volcanic rocks in Africa at some point during the 5th and 6th centuries AD. This preliminary evidence allows us to consider the networks and socio-economic factors that facilitated the distribution of ivory from Africa to the British Isles at this time.
