Resumen:
Nautiloids are represented in the Tertiary of Argentina by four genera and six species: Eutrephoceras sp., Hercoglossa rione-grensis, Hercoglossa romeroi (Ihering), Hercoglossa aff. H. walteri Miller, and Cimomia camachoi Masiuk, from the Paleocene Roca, El Fuerte and Salamanca formations, and Aturia caroliameg¬hinoi (Ihering), from the Eocene-Oligocene San Julián Formation. A shallow habitat is proposed for Hercoglossa aff. H. walteri. Paleoenvironmental conditions for the Argentinian Tertiary nautiloids were most favorable during the Danian; five species are known. The subclass Nautiloidea is not recorded in Argentina in post Oligocene rocks.
