无论他们如何测量石头，考古学家通常使用相互垂直的垂直尺寸，如长度和宽度。尽管正交尺寸很有用，但它并不能反映试件的几何形状。我们描述了一种包括三维激光扫描和几何形态测量的石块分析的替代方法。该方法保留了大量的几何信息，总体上更忠实于整体对象的形式。使用地标--在不同标本上的相同位置上的点--它还利用了传统上不在岩屑分析中使用的强大的分析技术。我们举例说明了这种方法及其在研究一小部分古印度凹槽点中的分析潜力。
ABSTRACT However they measure stone took, archaeologists typically use orthogonal—mutually perpendicular—dimensions like length and width. Although useful, orthogonal dimensions do not capture the geometric configuration of specimens. We describe an alternative approach to lithic analysis that involves three- dimensional laser scanning and geometric morphometries. This approach preserves much geometric information and generally is more faithful to whole-object form. Using landmarks—points at equivalent positions on different specimens—it also exploits powerful analytical techniques not traditionally used in lithic analysis. We illustrate the approach and its analytical potential in the study of a small collection of Paleoindian fluted points.
