A study of Jomon-period dolphin fishing by an individual identification analysis of animal remains

马瓦基遗址的主要海豚骨骼清单已输入：颅骨(105块)、下颌骨(65块)、肩胛骨(190块)、桡骨(141块)、尺骨(119块)和关节椎骨(从XI层内6m×15m的网格中(每个单元另加1/2m^2))；来自XI层的肱骨(187块)和地图集(286块)。通过粗略配对的方法搜索到6对(18.46%)与相同个体或其可能性较高的下颌骨。用微小配对的方法搜索到2对(2.14%)的肱骨，它们是相同个体的或高可能性的。检索到3组(9.38%)相同个体的或其可能性较高的关节椎体，其数据与目前的一只斜纹夜蛾的椎体长度测量相输入。虽然是从临海屠宰场附近的垃圾场挖掘出来的，但通过体骨配对或关节脊椎动物的个体鉴定，只找到了几个相同个体或其高度可能性的例子。可以假设，如果一个渔获物在劳动力动员方面很差，邻近聚居地的成员在一起捕捞海豚，一个聚居地不可能分享一整只海豚，或者，如果不同部分可能有一些有用的部分被分割并在聚居地之间分配，在那里进一步屠宰，骨头残骸就被扔进每个垃圾场。为了验证这一假说，有必要促进不同部位之间的个体认同分析：颅骨、下颌骨、地图集、肱骨和其他部位。

Inputted have been the lists of main dolphin bones from the District at the Mawaki site : craniums (105 pieces), mandibles (65 pieces), scapulas (190 pieces), radiuses (141 pieces), ulnas(119 pieces) and articulated vertebras from an excavation grid of 6m by 15m (with an additional 1/2m^2 for one unit) within Stratum XI ; humeri (187 pieces) from Stratum XI and atlases (286 pieces) from the stratums.Six pairs (18.46%) of mandibles were searched out as those of the same individuals or of their high possibilities by a rough pairing method. Two pairs (2.14%) of humeri were searched out as those of the same individuals or of their high possibilities by a minute pairing method. Three sets (9.38%) of articulated vertebras were searched out as those of the same individuals or of their high possibilities ; their data was inputted with length measurements of corpus vertebrae of a present Lagenorhynchus obliquidens. Only a few examples of the same individuals or of their high possibilities were searched out, either by the humeri pairing or the individual identification of articulated vertebras, although excavated from dumps near a butchery facing a fishery coast.It may be assumed that, if a catch was poor for labor mobilization, members of neighboring settlements working together in dolphin fishing, it was impossible for a settlement to have a share of a whole dolphin or that, if different parts probably of some usefulness were divided and distributed among settlements, where they were further butchered, the bone remains were thrown into each dump. It is necessary for verification of this hypothesis to promote individual identification analyses between different parts : craniums, mandibles, atlases, humeri and others.
