Measuring core reduction using 3D flake scar density: a test case of changing core reduction at Klasies River Mouth,South Africa

A new core reduction index is presented, calculated as the ratio of flake scar number to 3D surface area (SDI). The index is tested experimentally on five types of core (blade, discoid, Levallois, biface and multiplatform cores) and then applied to the core assemblages from five sub-stages of the Middle Stone Age at Klasies River Mouth, South Africa. Preliminary results indicate that the SDI possesses the desirable attributes of a successful reduction index and is a significant improvement on traditional proxy measures of core reduction. The results of the archaeological case study confirm previous untested observations that cores from the Howiesons Poort and MSAIII sub-stages are more heavily reduced than preceding and following stages, and that local and exotic raw materials as well as different types of cores are all more heavily reduced during these periods. The SDI fills a significant lacuna in available core reduction measures.     

Quantifying flake scar patterning on cores using 3D recording techniques

A key feature of stone artefact morphology is the arrangement and patterning of negative flake scars left on flakes and cores. Scar patterning is often treated as a rough guide to identifying methods of core preparation and reduction and usually forms a key component of lithic typologies and other systems of analysis. However, scar patterns are often complex and difficult to capture using traditional measurement or classificatory techniques, particularly where flakes are thick and irregular, or where cores are flaked on many sides from a number of platforms. Three-dimensional analysis of flake scars is now more feasible using digital 3D surface scanning technologies, or using three-dimensional measurement tools such as the Microscribe-3DX which is now widely used in biological geometric morphometric studies more generally [D.C. Adams, F.J. Rohlf, D.E. Slice, Ital. J. Zool., 71 (2004) 5–16; F.J. Rohlf, L.F. Marcus, Trends Ecol. Evol. 8 (1993) 129–132. [1 and 34]]. This paper develops a mathematical formula for describing scar patterning using vectors calculated from the start and end points of flake scars recorded in three dimensions.     

古器物纹饰传拓中的“看”与“做”

在现代文物展览、文物类图书出版中,对古器物纹饰部分进行拓片制作日益受到重视。本文是作者在多年的文物传拓实践中,对如何用传拓的手段来表现器物纹饰美感的理论认识。本文的观点是:传拓古器物纹饰,必须要深入把握古器物的纹饰内容和雕(铸)造层次,并通过对墨色浓淡变化的自觉控制,才能达到“传神”地再现古器物纹饰神韵的目的。     

A Research Note on Austronesian Relationship Terminologies With and Without Relative Age Categories

This research note examines the formal patterning of Austronesian relationship terminologies with or without relative age categories. Specifically, the article considers (1) the formal contrast between these patterns, (2) the key variant forms of these patterns, and (3) the distribution of these patterns and their associated variants throughout the Austronesian-speaking world. It offers a succinct examination of a key dimension of Austronesian terminologies and points to the position of eastern Indonesia as an innovative transition zone in the development of Austronesian terminologies.     

Refuse patterning and behavioral analysis in a pinniped hunting camp in the Late Jomon Period: A case study in layer V at the Hamanaka 2 site,Rebun Island,Hokkaido, Japan

During the Dobayashi New Phase (ca. 1450 cal BC–1300 cal BC), the Jomon maritime hunter–gatherers established pinniped hunting camps at the Hamanaka 2 site on Rebun Island, Hokkaido, Japan. They used the camps for animal processing and possibly cooking meat or processing fat using pottery vessels. Concentrations of conjoinable pottery around hearth features reveal that hearths were centers of activity. Analysis of conjoinable pottery within the excavated areas also indicates that artifacts were moved for the purposes of maintenance and cleaning of the hearths and activity areas.
