Izumonauta is an extinct genus of shelled octopods from the Mid to Late Miocene of Japan and New Zealand.[1]
The keels of Izumonauta eggcases lack tubercules and are intermediate in morphology between those of the earlier Obinautilus and later Argonauta.[2]
The New Zealand fossil material was described from the Kapitean Stage (uppermost Miocene).[3]
