It offers abundant occurrence of fossil as well as a spectacular diversity of extant endemic species, whose ancestors were escaped extinction during the latest Pleistocene. In the Ryukyu Islands, fossil assemblages of terrestrial vertebrates occur at three major stratigraphic levels, ranging from the Early to Late Pleistocene. These fossil assemblages represent successful colonizations by taxa that migrated from Asian mainland during the past four land connections. The taxa including archetypal deer and terrestrial tortoise complately extinct at the end of Pleistocene after the morphotypes. Furthermore, it can be said that the other animals in this assemblages may serve as the present endemic mammals, reptiless and amphibians living in the Ryukyu Islands. To know the age of mass extinction of terrestrial vertebrates in the Ryukyu Islands, ^<14>C ages of land snails which collected from four vertebrate fossil beds(cave and fissure deposits) in Okinawa Island together with abundant fossil vertebrates, were measured with Tandetron Accelerator Mass Spectrometry (AMS) of Dating and Matrerial Research Center, Nagoya University. The results are as follows. ^<14>Cages of fossil land snails from Okinawa Island indicate ages of Late Pleistocene ranging from ca. 23,000〜28,160 yrs. BP. These ^<14>C age are in accord with data presented by several previous researchers from the fissure and cave deposits of Okinawa and Miyako Islands. These data imply that the mass extinction of endemic archetypel deer and terrestrial tortoises might took placed at the third subglacial stage of the Wurm pleniglacial in the latest Pleistocene.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"第16回名古屋大学タンデトロン加速器質量分析計シンポジウム(平成15年(2003年度)報告 Proceedings of the 16th Symposium on Researches Using the Tandetron AMS System at Nagoya University in 2003 日時:平成16(2004)年1月22日(木)､23日(金) 会場:名古屋大学シンポジオン Date:January 22nd and 23rd,2004 Place:Nagoya University Symposion Hall","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/sumrua.15.41","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学年代測定資料研究センター","subitem_publisher_language":"ja"}]},"item_9_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110007150897/","subitem_relation_type_select":"URI"}}]},"item_9_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"名古屋大学年代測定資料研究センター","subitem_rights_language":"ja"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである","subitem_rights_language":"ja"}]},"item_9_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_9_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大塚, 裕之","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"81610","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Otsuka, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"81611","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中村, 俊夫","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"81612","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakamura, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"81613","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"太田, 友子","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"81614","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ota, Tomoko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"81615","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-20"}],"displaytype":"detail","filename":"KJ00005461756.pdf","filesize":[{"value":"685.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00005461756.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/11722/files/KJ00005461756.pdf"},"version_id":"a74628c0-14ae-445f-ada6-209031568977"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"沖縄島における第四紀脊椎動物化石包含層の ^<14>C年代(第16回名古屋大学タンデトロン加速器質量分析計シンポジウム平成15(2003)年度報告)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"沖縄島における第四紀脊椎動物化石包含層の ^<14>C年代(第16回名古屋大学タンデトロン加速器質量分析計シンポジウム平成15(2003)年度報告)","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"17","path":["1244"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-06-03"},"publish_date":"2010-06-03","publish_status":"0","recid":"11722","relation_version_is_last":true,"title":["沖縄島における第四紀脊椎動物化石包含層の ^<14>C年代(第16回名古屋大学タンデトロン加速器質量分析計シンポジウム平成15(2003)年度報告)"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-11-13T05:24:50.139912+00:00"}
