Three odontaspidid fossil shark teeth previously reported from the “Lower Formation” of the Upper Cretaceous Mifune Group in Yamato Town and Mifune Town, Kumamoto, Japan as three separate taxa (“Carcharias” amonensis, “C.” cf. amonensis, and “Carcharias” sp.) are reexamined and described in detail. Restudy shows that all of these shark teeth should be assigned to the species “Carcharias” amonensis. These specimens establish that “C.” amonensis also inhabited the Pacific region and thus had a worldwide distribution in the temperate sea in the Cretaceous.
