翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Euomphaloidea ： ウィキペディア英語版 Euomphaloidea Euomphaloidea, originally Euomphalacea, is an extinct superfamily of marine molluscs that lived from the Early Ordovician to the Late Cretaceous, included in the Gastropoda〔〔Moore R. C., Lalicker & Fischer (1952). ''Invertebrate Fossils''. McGraw-Hill publisher.〕 but speculated as instead perhaps Monoplacophora. ==Description== Euomphaloid shells are mostly discoidal and may be either orthostrophic (coils wrapped around an erect cone) or hyperstrophic (coils wrapped around an inverted cone); are widely umbilicate and commonly have a channel, presumed exhalent, within the angulation in the outer part of the upper whorl surface. The shell wall is relatively thick, with an external prismatic layer of calcite, which may be pigmented, and an internal layer of lamellar, but not nacreous, aragonite.〔(1960).
