Eobucania (Mollusca) from the Furongian (late Cambrian) of Sweden

The isometrically coiled mollusc Eobucania Kobayashi, 1955 is described from the Peltura scarabaeoides Zone (Furongian; late Cambrian) of Kinnekulle, southern Sweden, representing the oldest record of the genus and the first from the Cambrian of Sweden. While originally described from the Lower Ordovician strata within the McKay Group of British Columbia, Canada, additional species of Eobucania have been reported from the Lower Ordovician of Mexico, France and the Czech Republic, and ostensibly from the Lower Devonian of China. Eobucania has been widely interpreted as a bellerophontoidean gastropod, but placement within the monoplacophoran Class Tergomya is possible.
