Early Carboniferous (Visean) brachiopods from the Hina Limestone, Okayama Prefecture, SW Japan, and their palaeobiogeographical implications Early Carboniferous (Visean) brachiopods from the Hina Limestone, Okayama Prefecture, SW Japan, and their palaeobiogeographical implications Tazawa, Jun-ichi Ibaraki, Yousuke Nishikawa, Isao Brachiopoda Hina Limestone palaeobiogeography southwestern Japan Visean A brachiopod fauna consisting of 9 species in 8 genera is described from the lower part (Endothyra Zone) of the Hina Limestone, Okayama Prefecture, southwestern Japan. The Hina fauna includes the following species: Leptagonia analoga, Dictyoclostus pinguis, Marginatia burlingtonensis, Marginatia cf. magna, Schizophoria resupinata, Cleiothyridina sp., Spirifer cf. liangchowensis, Grandispirifer sp. and Syringothyris cf. cuspidatus. The Hina fauna has some affinities with the Early Carboniferous (Visean) brachiopod faunas of South Kitakami, Xinjiang, Kirgiz, Kazakhstan, Kuznetsk Basin, Urals and England. The palaeobiogeographical data suggest that the Akiyoshi-type reef‒seamount complexes, including the Hina Limestone, were probably located at mid-atitudes of the Northern 新潟大学理学部 2016-03 eng departmental bulletin paper http://hdl.handle.net/10191/42100 https://niigata-u.repo.nii.ac.jp/records/6733 AA11436808 13491237 Science reports of Niigata University.
