The result revealed that S. biwaensis was more widely distributed in the past time than at present, and agreed with the hypothesis of Kobayakawa and Okuyama（1994） that S. biwaensis is a relict species. Furthermore, it was suggested that a more detailed comparative morphological study of the skull elements（e.g. morphology of the sagittal crest and adjacency relation between the bones composing the neurocranium）is needed to clarify the phylogenetic relationships in the genus Silurus.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20643/00001609","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"大阪市立自然史博物館"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0078-6675","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"樽野, 博幸"},{"creatorName":"タルノ, ヒロユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"296","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Taruno, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"298","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":"2022-03-31"}],"displaytype":"detail","filename":"04_樽野博幸_31-55.pdf","filesize":[{"value":"34.3 MB"}],"format":"application/pdf","licensetype":"license_9","mimetype":"application/pdf","url":{"label":"Taruno_31_55","url":"https://omnh.repo.nii.ac.jp/record/1650/files/04_樽野博幸_31-55.pdf"},"version_id":"b1692b8a-2496-4e4b-8d6d-d76f0a445b0d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Central Japan","subitem_subject_scheme":"Other"},{"subitem_subject":"Osaka Group","subitem_subject_scheme":"Other"},{"subitem_subject":"Pleistocene","subitem_subject_scheme":"Other"},{"subitem_subject":"Pliocene","subitem_subject_scheme":"Other"},{"subitem_subject":"relict","subitem_subject_scheme":"Other"},{"subitem_subject":"Silurus biwaensis","subitem_subject_scheme":"Other"},{"subitem_subject":"skull morphology","subitem_subject_scheme":"Other"}]},"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":"大阪湾の海底から発見されたビワコオオナマズの頭骨の化石","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"大阪湾の海底から発見されたビワコオオナマズの頭骨の化石"},{"subitem_title":"Fossil skulls of Silurus biwaensis from the sea bottom of Osaka Bay","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"11","path":["283"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-03-31"},"publish_date":"2022-03-31","publish_status":"0","recid":"1650","relation_version_is_last":true,"title":["大阪湾の海底から発見されたビワコオオナマズの頭骨の化石"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-05-15T13:01:59.400672+00:00"}
