|Ornaments found in Mitchell Ridge included beads and tinklers made from two related small gastropods, Olivella and the Lettered Olive (Oliva sayana). The top and middle rows are tinklers, or bell-shaped ornaments thought to have suspended from clothing or necklaces so that they could strike one another and make a light ringing sound. All of the Mitchell Ridge tinklers were made of Oliva sayana, a larger species than Olivella. Small beads of the latter are shown on the bottom row. Adapted from Ricklis 1994, Figures 8.17 and 8.34.
