Observation of their skeletons by scanning electron microscopy (SEM) reveals that they possess a pore larger than openings of the spongiose meshwork in the skeleton surface. The pore is the site through which the axoflagellum projects outward and is named axoflagellum pore. This paper describes some features of the axoflagellum pore of Dictyocoryne truncatum (Ehrenberg), Spongaster tetras tetras Ehrenberg, Spongodiscus biconcavus Haeckel, and Euchitonia elegans (Ehrenberg), showing SEM photos which were taken from different view points on a single specimen. These discoidal spumellarian species float in seawater generally keeping their skeletons horizontal. The position of axoflagellum pore gives useful information on the orientation in floating. This paper draws the orientation of floating D. truncatum and E. elegans. The position and shape of axoflagellum pore differs among species, suggesting that the features of axoflagellum pore can be useful in distinguishing species and in discussing their phylogenetic relationship.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"39399","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Matsuoka, Atsushi"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本古生物学会"}]},"item_5_relation_31":{"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/110002703583","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本古生物学会"},{"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_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00041606","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00229202","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松岡, 篤"}],"nameIdentifiers":[{"nameIdentifier":"39398","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":"2019-07-30"}],"displaytype":"detail","filename":"110002703583.pdf","filesize":[{"value":"4.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"110002703583.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2845/files/110002703583.pdf"},"version_id":"c76ae4a8-7932-4fce-be1c-d7afcba1c339"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"平板状スプメラリア（放散虫）のアクソフラジェルムと殻にみられるその通過孔","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"平板状スプメラリア（放散虫）のアクソフラジェルムと殻にみられるその通過孔"},{"subitem_title":"平板状スプメラリア（放散虫）のアクソフラジェルムと殻にみられるその通過孔","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","489"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-04-05"},"publish_date":"2012-04-05","publish_status":"0","recid":"2845","relation_version_is_last":true,"title":["平板状スプメラリア（放散虫）のアクソフラジェルムと殻にみられるその通過孔"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:04.619826+00:00"}
