Argonautidae is a family of cephalopods encompassing the modern paper nautiluses of the genus Argonauta along with several extinct genera of shelled octopods.
All eggcases possessing nodes, ribs, and a double keel, with the exception of those of Kapal batavus, have been assigned to Argonauta. Eggcases lacking these morphological features have been placed in the other Argonautidae genera.[1]
Fossil Argonautidae eggcases have been described from Japan, New Zealand, Sumatra, Europe, and California.[1]
