Collagens were extracted from fossil samples by pretreatment and HCl-demi-neralization following to gelatinization process, and two kinds of collagens, HCl-soluble and -insoluble gelatin collagen, can be obtained. The two kinds of collagens extracted from the same sample coincide well for respective values of C/N ratio, δ^\u003c13\u003eC and radiocarbon age. The both collagens, therefore, can be used for the radiocarbon age determination and the ^\u003c13\u003eC-environmental analysis. The radiocarbon age of well-preserved molar, tusk and horn samples containing more than 0.7% (C/N rations of these samples show 3.0 to 3.9 without exception) closely coincides with that of wood fossils from the same horizon. On the other hand for the poorly preserved collagens containing less than 0.7% having larger C/N ratios than 4.0,the ^\u003c14\u003eC dating indicates the younger age in 5 to 10 thouthands years compared with that of wood fossils which is well preserved, showing generally reliable ^\u003c14\u003eC age. So it can be said that (1) most molars of Naumann\u0027s elephant fossils and most horns of Yabe\u0027s deer fossils are reliable for the ^\u003c14\u003eC age determination, resulting in rasonable ^\u003c14\u003eC ages, (2) all the tusks of elephant samples and bones of deer samples are not reliable, showing too young ages, and (3) in the case of Sika deer (Cervus nippon) fossils from the Holcene, all and both horns and bones are well-preserved to determine the ^\u003c14\u003eC age. Using only well-preserved mammal molar, horn and bone samples their ^\u003c14\u003eC ages and δ^\u003c13\u003eC values have been analysed and the following results were obtained in the present study. For Nojiriko samples, (1) The ^\u003c14\u003eC ages of Naumann\u0027s elephant and deer fossils range from 50×10^3 to 35×10^3 Yr.BP. (2) Domestic stone impliments belonging to the paleolithic man occur in the Nojiriko formation where the Naumann\u0027s elephant and deer fossils can be found. Therefore, it can be concluded from the ^\u003c14\u003eC ages of mammal fossils that the paleolithic man so called \"Nojiriko man\" is not a Neanthropic man (Neoanthrope ; Homo sapiens sapiens) but a Paleo-man (Paleoanthrope ; Homo sapiens neanderthalensis). (3) A rising trend of the atmospheric temperature from 50 thousands to 35 thousands years B.P. could be proved by δ^\u003c13\u003eC measurements and ^\u003c14\u003eC ages of the collagens extracted from the Naumann\u0027s elephant and deer fossils. This temperature-rising trend corresponds to a temterature increase of \"GLACIAL STADIAL\" to \"INTERGLACIAL\" during the last Glacial Age, the WURM Glacial Age. For the Kantoh Plain samples. (1)The ^\u003c14\u003eC ages of Sika deer (Cervus nippon) fossils range from 5,090 Yr, B.P. to 2,820 Yr.B.P. (2) A dropping trend of the temperature could be found from 4,000 to 3,500 Yr.B.P. in the Kantoh Plains based on δ^\u003c13\u003eC measurements and ^\u003c14\u003eC ages of the collagens from Sika deer fossils.", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/sumrua.3.7", "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 天然放射性元素測定小委員会"}]}, "item_9_relation_43": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110000475783/", "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 天然放射性元素測定小委員会"}, {"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"}]}, "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_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "中井, 信之"}], "nameIdentifiers": [{"nameIdentifier": "79477", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakai, Nobuyuki"}], "nameIdentifiers": [{"nameIdentifier": "79478", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "中村, 俊夫"}], "nameIdentifiers": [{"nameIdentifier": "79479", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakamura, Toshio"}], "nameIdentifiers": [{"nameIdentifier": "79480", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "有田, 陽子"}], "nameIdentifiers": [{"nameIdentifier": "79481", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Arita, Yoko"}], "nameIdentifiers": [{"nameIdentifier": "79482", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "森, 育子"}], "nameIdentifiers": [{"nameIdentifier": "79483", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Mori, lkuko"}], "nameIdentifiers": [{"nameIdentifier": "79484", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "亀井, 節夫"}], "nameIdentifiers": [{"nameIdentifier": "79485", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kamei, Tadao"}], "nameIdentifiers": [{"nameIdentifier": "79486", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "秋山, 雅彦"}], "nameIdentifiers": [{"nameIdentifier": "79487", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Akiyama, masahiko"}], "nameIdentifiers": [{"nameIdentifier": "79488", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "沢田, 健"}], "nameIdentifiers": [{"nameIdentifier": "79489", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sawada, Ken"}], "nameIdentifiers": [{"nameIdentifier": "79490", "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", "download_preview_message": "", "file_order": 0, "filename": "KJ00000187518.pdf", "filesize": [{"value": "965.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 965600.0, "url": {"label": "KJ00000187518.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/11322/files/KJ00000187518.pdf"}, "version_id": "f7d396d8-5fc9-46a7-81f7-94b1923764df"}]}, "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": "哺乳動物化石の\u003c14\u003e^C年代測定と\u003c13\u003e^Cによる環境変動の解明 : 野尻湖ナウマンゾウ・オオツノシカ,関東地方ニホンシカを中心として", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "哺乳動物化石の\u003c14\u003e^C年代測定と\u003c13\u003e^Cによる環境変動の解明 : 野尻湖ナウマンゾウ・オオツノシカ,関東地方ニホンシカを中心として"}]}, "item_type_id": "9", "owner": "1", "path": ["1221"], "permalink_uri": "https://doi.org/10.18999/sumrua.3.7", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-04-26"}, "publish_date": "2010-04-26", "publish_status": "0", "recid": "11322", "relation": {}, "relation_version_is_last": true, "title": ["哺乳動物化石の\u003c14\u003e^C年代測定と\u003c13\u003e^Cによる環境変動の解明 : 野尻湖ナウマンゾウ・オオツノシカ,関東地方ニホンシカを中心として"], "weko_shared_id": null}
