UCDZL - Mollusk collection

The mollusk collection has grown since an 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 shellfish consumption at sites near Bodega Bay. The collection now houses nearly 470 specimens representing 82 different shell species.
