Olivella biplicata'' was used to make beads for at least 9,000 years. The small numbers recovered in older archaeological site components suggest that they were initially used as
ornamentation, rather than as money. Beginning shortly before 1,000 years ago,
Chumash specialists on the islands of California's Santa Barbara Channel began chipping beads from olive shells in such quantities that they left meter-deep piles of manufacturing residue in their wake; the resulting circular beads were used as money throughout the area that is now southern California.
