Late Holocene Size Variation of Mytilus californianus Remains from Shelter Cove (CA-HUM-182), Northern California

Abstract

ABSTRACT Here we evaluate variation in Mytilus californianus size from CA-HUM-182, comparing patterns with those from Punta Gorda Rock Shelter that suggested sustainable resource management. Using a novel equation, we reconstruct the size profile of the assemblage over time and provide a new age-depth chronology. Results indicate no decrease in size over time; instead, increases are observed from initial harvest (∼730 cal BP) to site abandonment (∼260 cal BP), suggestive of sustainable practices and the possibility of conservation.
