• Resumen

  • New species of Diplodon Spix (Bivalvia, Unionidea) from the Middle Jurassic (La Matilde Formation), of Santa Cruz province, Argentina. Two new species, Diplodon simplex Morton n. sp. and Diplodon matildensis Morton n. sp. are described from the Middle Jurassic La Matilde Formation of Santa Cruz province, Argentina. These findings reinforce some ideas of the southern origin and dispersal of this group of bivalves. Additionally, the gastropod Potamolithus sp., associated with Diplodon, is briefly described.
