UCDZL - Mollusc collection

The mollusc collection has grown since initial ad-hoc collection began in the late 1960s as a means of understanding shell artifacts from California archaeological assemblages. In the early 2000s graduate student Michael Kennedy increased the collection considerably with his research on prehistoric shell consumption at sites near Bodega Bay. The collection now houses 495 specimens representing 81 different shell species.
