Fossil Asterozoa (Echinodermata) of Argentina / Fósiles de Asterozoa (Echinodermata) de Argentina

Abstract Thefossil Asterozoa of Argentina have received scant attention. Marine rocks of Early Devonian-Late Miocene age yield ten species of Asterozoa (four Asteroidea and six Ophiuroidea), including the new Neogene record of Astropecten sp. presently introduced. Due to homonymy, Marginix nomen novum is proposed as a substitution of Marginura (Ophiuroidea, Encrinasteridae). Rev. Biol. Trop. 63 (Suppl. 2): 1-6. Epub 2015 June 01.

Resumen Se registran 10 especies de Asterozoa fósiles de Argentina (cuatro Asteroidea y seis Ophiuroidea), desde el Devónico Temprano hasta el Mioceno Tardío, incluyendo un nuevo registro de Astropecten sp. Por homonimia, Marginix nomen novum es propuesto para sustituir a Marginura (Ophiuroidea, Encrinasteridae).
