Two corbiculoid species from the Lower Jurassic Iwamuro Formation are described in this paper. Characteristics of the fauna and the strategy of early Jurassic corbiculoid species during marine transgression are discussed. Based on biogeographical and biostratigraphical distribution of both Eomiodon vulgaris and Crenotrapezium kurumense, Eomiodon vulgaris appeared to be exterminated by marine transgression in the southern Kitakami area. In the Hokuriku area, both Eomiodon vulgaris and Crenotrapezium kurumense were interpreted to have retreated into a refuge during the first marine transgression, but they were exterminated by the second marine transgression
