Animals in the sanctuary. Bird bones and eggshell By Dale Serjeantson (University of Southampton, United Kingdom) Abstract Excavations at the Sanctuary of Poseidon at Kalaureia and the application of a systematic soil sampling and water flotation programme led to the collection of a moderate amount for bird bones and eggshell fragments. Their dating in the first millennium BC and their association with cult renders them a significant addition to the extant bird remains record in Greece. In this paper the bird and egg remains are presented in detail by chronological phase and by feature, they are compared with other contemporary assemblages of bird remains, and some commentary is offered on their significance.
