The Misakubo Formation is narrowly distributed along the eastern side of the Sambagawa Belt and the Miocene Tokizawa Formation in the northern part of Misakubo, Hamamatsu, Shizuoka Prefecture. This formation consists mainly of black mudstone, fossils yielding bivalves, ammonoids, gastropods and crinoids. Late Albian mid-Cretaceous ammonoids such as Mortoniceras rostratum, Desmoceras latidorsatum, Desmoceras sp., Mariella sp., and Lechites sp. are found in the upper part of the formation. Shallow marine bivalve assemblage yielded in the formation is predominated by Pterotrigonia pustulosa. The fossil bivalve assemblage is compositionally similar to the inner shelf assemblages of the Enokuchi Formation of the Goshoura Group; the Miyanohara Formation, the Fukkoshi Formation and the Nagase Formation of the Sotoizumi Group and the Mikasa Formation of the Yezo Group. The range of these trigoniids might be incorrect, because Pterotrigonia mifunensis and Pterotrigonia monobeana yielded with M. rostratum. http://www.journalarchive.jst.go.jp/japanese/jnlabstract_ja.php?cdjournal=jgeography1889&cdvol=115&noissue=5&startpage=626 journal article 社団法人 東京地学協会 2006-12-25 VoR application/pdf 地學雜誌 5 115 626 637 AN00322536 https://kumadai.repo.nii.ac.jp/record/24675/files/115_626.pdf http://hdl.handle.net/2298/18695 https://kumadai.repo.nii.ac.jp/records/24675 jpn 0022135X (c) Tokyo Geographical Society
