This thesis was to develop a bone artifact typology for the Oregon coast. This typology was used to test the hypothesis that different geographical regions of the Oregon coast would have different artifact assemblages associated with them. These regions, identified by geologist from landform changes, have been defined as: region 1, from the Columbia River to Tillamook Head; region 2, from Tillamook Head to Heceta Head; region 3, from Heceta Head to Cape Arago; region 4, from Cape Arago to the California boarder. Three criteria were used to develop the bone artifact typology; (1) the artifact must be made from bone, antler, or tooth; (2) the use of the artifact as determined from previous experimental archaeology or ethnography; (3) where artifacts were used for a similar purpose, obvious differences in shape and/ or decoration were used. Fifteen sites on the Oregon coast, two to four sites from each region, were used to develop the typology and test the hypothesis. Some patterns were apparent in the distribution of the artifact assemblages from the Oregon coast sites and there appeared to be some tentative corralation with the geographic regions as stated above. Bilaterally barbed harpoons only appear in sites in region 1. Headscratchers only appear in sites in the southern half of the Oregon coast. Evidence suggested that the composite toggling harpoon was developed in the northern northwest coast and was introduced 3000 or more years ago in region 1, and spread slowly down the Oregon coast until it reached region 3 and 4 only 500 years ago. / Graduation date: 1991
