Permian lyttoniid brachiopod <i>Petasmaia</i> from Akasaka, Mino Belt, central Japan

Permian Panthalassan brachiopods <i>Eolyttonia</i> and <i>Permophricodothyris</i> from Akasaka, central Japan

“…Therefore, the occurrence of Eolyttonia diabloensis and Permophricodothyris horii in the Akasaka Limestone very likely suggests that in the Permian, the Akasaka area was located in the mid-Panthalassan equatorial region between the Palaeotethys Ocean and the North American continent. This conclusion is consistent with the recent studies on Permian brachiopods of the Kuzu (Tazawa et al, 2010(Tazawa et al, , 2012b, Kiryu (Tazawa and Takakuwa, 2009;Tazawa et al, 2012a), Hatahoko (Shen et al, 2011), Hiyomo (Tazawa and Shen, 1997) and Akasaka (Tazawa et al, 1998;Tazawa and Ono, 2013) areas of the Mino Belt.…”

A Kungurian (Early Permian) Panthalassan brachiopod fauna from Hatahoko in the Mino Belt, central Japan

“…residua Cooper andGrant, 1975, Anomaloria hiyomoensis Shen, 1997, Calliprotonia sp., Cartorhium coristum Cooper andGrant, 1976, Cenorhynchial sp., Chonetinella cf. costellata Cooper andGrant, 1975, Glyptostegesl sp., Lepidospirifer miyakei Tazawa andShen, 1997 and Martinia semiplana Waagen, 1884, Peltichia akasakaensis (Ozawa, 1927) from Akasaka and Hiyomo in the Mino Belt, were previously described (Tazawa, 1997;Tazawa and Shen, 1997;Tazawa et al, 1998;Shen et al, 1999 U.S.A. Thus, all the brachiopod faunas in the Mino Terrane from Kungurian to Guadalupian exhibit a strong paleobiogeographical affinity with the brachiopod faunas of West Texas in the western margin of the North American Platform.…”
