Eleven ammonite species from five localities in the Ieru Formation, western Papua New Guinea, are described. Four are identified with the well known and widely distributed Cenomanian species of the Acanthoceratidae, Calycoceras (Newboldiceras) newboldi (Kossmat), C. (N.) cf orientale Matsumoto and others, C. (N.) annulatum Collignon and Acanthoceras rhotomagense (Brongniart). Other Cenomanian taxa are three indeterminable acanthoceratid species, C. (Calycoceras) sp. nov .(?), Calycoceras subgenus et sp. indet., and Acanthoceras sp. indet., as well as Pachydesmoceras sp. nov. and Chimbuites aff. mirindowensis Wright. The Turonian species Romaniceras deverioides (de Grossouvre) was found with Placenticeras aff. tamulicum (Blanford); several fragments, probably from the Star Mountains, are also referred to P. aff. tamulicum.
