dc.descriptionSe describen restos fragmentarios de nautilidos del genero Cymatoceras Hyatt, provenientes de estratos barremianos de la Cuenca de Atacama, norte de Chile. Los especimenes corresponden a dos taxones: Cymatoceras sp. del Barremiano tardio alto, cuya preservacion es deficiente, aunque su tipo de ornamentacion, con costillas gruesas y un seno ventral muy marcado, es solo conocida, hasta el momento, en este taxon y Cymatoceras cf. perstriatum (Steuer), del Barremiano tardio. El material chileno es comparado, principalmente, con taxones de Cymatoceras presentes en las cuencas Neuquina y Austral, en Argentina.es-ES
dc.descriptionFragmentary remains of nautilids assigned to the genus Cymatoceras Hyatt, found in Barremian strata at the Atacama Basin, northern Chile, are described. The specimens can be divided into two taxa: Cymatoceras sp., from the late Upper Barremian, that has a poor preservation, but at the moment its ornamentation type, with coarse ribs with a marked ventral sinus, is only known from this taxon, and Cymatoceras cf. perstriatum (Steuer), from the Upper Barremian. The Chilean material is mainly compared with Cymatoceras taxa present at the Neuquén and Austral basins, in Argentina.en-US
