Dentalium (1/2-1") 1-kg
Dentalium aprinium is used in indigenous jewelry, adornment, and commerce in western Canada and the United States. These tusk shells are a kind of seashell, specifically the shells of scaphopod mollusks.
Dentalium shells were used by Inuit, First Nations, and Native Americans as an international trade item. This usage is found along the western coast of Canada and along the Pacific Ocean coast of the northwest United States, extending southward to Southern California.
