Newly collected specimens of the large bivalve Vesicomya inflata Kanie & Nishida from the lower Cenomanian Tenkaritoge Formation reveal that it is not I vesicomyid but is instead all unusual lucinid. The new monotypic genus Ezolucina is herein proposed for this species, which is characterized by venerid or vesicomyid shell shape. large size, a smooth surface, a deeply impressed lunule. one cardinal and one anterior lateral tooth in the right valve. and two cardinal teeth in the left valve. Stable carbon isotope analyses and petrographic observations show that the carbonate concretions yielding this species do not represent ancient hydrocarbon-seep deposits as was suggested previously. Rather. Ezolucina inflata and the associated solemyid, lucinid, thyasirid, and manzanellid bivalves lived in organic- and sulfide-rich sediment.
