Abstract

本稿は,埋葬時の遺体周辺が充填環境か空隙環境かによって骨の移動に差が生じるとの考え(奈良,2007)を基に,人骨の出土状況から遺体周辺の環境を判断するための基本事項を整理した。まずは,「充填環境」と「空隙環境」とは埋葬時から白骨化の完了までの遺体周辺の環境を表しており,白骨化の途中で空隙環境から充填環境へと移行する例を示すことで,環境変化を時間的に捉える必要性を指摘した。また,遺体の一部分が空隙となる「部分的空隙環境」には,土砂の流れ込みなど,空隙環境から充填環境への移行時に起こる状況と,遺体を包装するなどの理由で埋葬時から生じる状況の2パターンが存在すると考えた。そして,時間的変化を考慮して人骨の出土状況を観察することで,全パターンの判別と具体的な環境変化の復元が可能となるとの方法論を提示した。次に北村遺跡出土の縄文人骨42例に対して遺体周辺の環境判断を行い,方法論の検証を行った。まずは,充填環境においても遺体の腐食による沈み込みは存在し,埋葬姿勢によっては骨が移動することや,甕被り葬や枕石の存在が骨の移動の要因であることを明らかにした。その結果,明らかに判断可能な人骨の割合は95.2%を占め,人骨を用いた遺体周辺の環境判断は大部分が可能であることを示した。<br>

In this paper, the author summarizes the basic principles for analyzing the environments surrounding human remains given the excavated condition of bones, based on the idea that disparities in bone movement arise depending on whether the environment surrounding a body at the time of its burial was “filled” or “unfilled” (Nara, 2007). The author refers to the environments surrounding human remains from the time of their burial to the completion of skeletonization as either “filled” or “unfilled,” and, by presenting instances in which unfilled environments transform into filled environments during the course of skeletonization, the author notes the need to view environmental change in terms of time. Furthermore, it is considered that two patterns exist for “partially unfilled environments” in which a portion of the remains are unconcealed: conditions occurring in a transformation of an unfilled environment into a filled environment (such as landslides, etc.), or conditions occurring at the time of the burial of the body due to factors such as wrapping, etc. In addition, the author proposes a methodology that allows for the differentiation of each pattern as well as the re-creation of specific environmental changes by studying the excavated condition of human bones in view of temporal change. The author tested this methodology against 42 sets of human bones from the middle to late Jomon period unearthed at the Kitamura Site, conducting an analysis of the environment surrounding said remains. First, it was demonstrated that sinkage occurs even in filled environments due to decomposition of the body, that bones move depending on their burial position, and that pottery covering the face or the stone under the head were factors in bone movement. The results were that clearly discernable human bones made up 95.2% of the test specimens, and that the majority of analyses of environments surrounding human remains utilizing bones were valid.<br>
