Abstract

A mollusk assemblage with Anodontites aff. elongatus (Swainson), Anodontites trapesialis (Lamarck), Anodontites sp., Diplodon aff. delodontus Lamarck and the gastropod Pomacea aff. canaliculata Lamarck is described. This fauna, together with at least three species of the bivalve genus Neocorbicula Fisher, ostracods of the genus Cyprideis Jones and Charophyta indet. are from the Middle Miocene San José Formation, from the locality of Quebrada de Mal Paso, near Tolombón in the northern Santa Maria valley (Salta Province). The association would indicate tropical and/or subtropical fresh water bodies, zoogeographically belonging to the Neotropic Region. © 2012 by Unisinos.
