At the moment, the oldest fossil of the eye is the compound eye of the trilobite about 525 million years ago. We investigated the fossil localities of the older age, but we could not find organisms with eyes. We were able to identify to some extent potential sites for the fossils with eyes on the Early Cambrian strata.\nRegarding Ordovician and Devonian trilobites, CT scan was performed using well-preserved fossils, three-dimensional coordinates were acquired, the optical axis of each individual eye was determined, and then the field of view was estimated. The Ordovician trilobite, which is considered to be pelagic, can be estimated to have a wide field of view and live near the surface. On the other hand, the shallow-sea Devonian trilobite had a high resolution eye, though the vertical field of view was extremely narrow.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:16K05592, 研究期間(年度):2016-04-01 - 2019-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「眼の起源と古生物の視覚の復元に挑む」課題番号16K05592\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-16K05592/16K05592seika/）を加工して作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00055167","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学国際基幹教育院GS教育系"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=50437191"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=50437191","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-16K05592/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-16K05592/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-16K05592/16K05592seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-16K05592/16K05592seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-04-27"}],"displaytype":"detail","filename":"GS-PR-TANAKA-G-kaken 2019-6p.pdf","filesize":[{"value":"421.1 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"GS-PR-TANAKA-G-kaken 2019-6p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/48848/files/GS-PR-TANAKA-G-kaken 2019-6p.pdf"},"version_id":"364b162e-75e9-4134-99a9-1c3c56f2dea9"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"眼の起源と古生物の視覚の復元に挑む","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"眼の起源と古生物の視覚の復元に挑む"},{"subitem_title":"Challenging for an origin of eye and vision of ancient animals","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2815"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-04-27"},"publish_date":"2020-04-27","publish_status":"0","recid":"48848","relation_version_is_last":true,"title":["眼の起源と古生物の視覚の復元に挑む"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T13:32:59.091213+00:00"}
