Judging by the ethnographic collections at the Field Museum of Natural History, ceramic and wooden platters and shallow open bowls on the Sepik coast are not just analogous types of objects, but are alike derived historically from Lapita prototypes. Archaeological and ethnographic evidence from the Sepik coast documents the evident survival in the western Pacific of a stylized symbol or motif—the so-called Lapita face—on pottery and possibly other kinds of material items (such as wooden bowls and serving platters) for at least 3,300 years.
