摘要: High-resolution stable oxygen isotope analysis of the bivalve Saxidomus gigantea from shell midden sites was applied to identify seasonal patterns resource procurement on central coast British Columbia, Canada. A total 90 archaeological shells were examined eight distinct spanning a 4500-year period. Combining micro-growth pattern with high-resolution sampling allows for precise season collection be determined in estuarine bivalves recovered sites. The results provide insights into seasonally structured harvest S. gigantea (butter clam), which is associated different types show variety patterns, including multi-seasonal collection, intensive harvesting and casual, supplemental use butter clams at locations.
