Online material

Abstract

The online material consists of 24 figures and six Excel tables with multiple tabs each. Figures 1-8 show close-up views of the distribution of grave sites in the various sub-regions of the research area. Figures 9-13 show the distribution of megalithic graves by grave sub-type in various parts of the research area. Figures 14-20 show close-up views of the orientation of the graves in the various sub-regions of the research area. Figures 21-23 are schematic diagrams showing the orientation of the graves separate by grave type. Figure 24 shows the number of graves on each site displayed on a map. The first Excel table (Assemblages) shows the grave assemblages, in the first tab all of them together, the second to fourth tab special sub-sections of the material. The second Excel table (Correspondence Tables) displays the co-occurrence of various types of grave objects for various types of graves and objects including all objects in multiple consecutive interments (tab 1), ceramics from megalithic graves (tab 2), other objects from megalithic graves (tab 3), and combination of objects in graves at Xichang Lizhou (tab 4). The third Excel table (Graves: All Information) contains a list of all graves by location with details on orientation, measurements, preservation, content, and the like. The fourth Excel table provides location information, the first tab listing location accuracy, the second the reliability index, and the third the distance between graves and closest settlement for sites where that distance is less than 2 km. The fifth Excel table contains information on the size and shape of each object analyzed in this study; the material is displaced separate by material including ceramics (tab 1), stone tools (tab 2), metal ornaments (tab 3), other ornaments (tab 4), metal objects (tab 5), metal ritual objects (tab 6), and arrowheads (tab 7). The sixth Excel table displays all information used to assess the likelihood of reopening of the graves, in the first tab listing the graves by site name, in the second by likelihood of reopening.
