Early silurian rhodocrinitacean crinoids brassfield formation ohio usa



Early silurian rhodocrinitacean crinoids brassfield formation ohio usa



Journal of Paleontology 60(1): 84-106



Six Early Silurian Rhodcrinitacea (Crinoidea, Camerata) are recognized from the Brassfield Formation of Ohio. Previously, only a single Early Silurian rhodocrinitacean was known. The new forms include KYREOCRINUS constellatus n. gen., n. sp.; RHACHICRINUS wrighti n. gen., n. sp.; SILFONOCRINUS siluricus n. gen., n. sp.; Stereoaster squamosus Foerste; XYSMACRINUS greenensis n. gen., n. sp.; and TURBOCRINUS punctum n. gen., n. sp. Rhachicrinus and Silfonocrinus are assigned to the Opsiocrinidae, which previously included two Devonian genera; Turbocrinus is assigned to the Anthemocrinidae; and Kyreocrinus, Stereoaster and Xysmacrinus are assigned to the Rhodocrinitidae. The Opsiocrinidae are thought to be derived from the Reteocrinidae; and a possible basis for subdividing the Rhodocrinidae is proposed, based on the arms, plating in regular interrays, presence of median ray ridges and calyx shape.
