Diversity of Cretaceous continental actinopterygians from Argentina, South America

Abstract

South America holds a signiicant number of continental ish-bearing deposits of Cretaceous age. The principal purpose of the current article is to illustrate the diversity of continental actinopterygian assemblages of the main Cretaceous localities from Argentina, southern South America, providing an updated review and a discussion about their particular history. Various aspects of the knowledge concerning Cretaceous continental actinopterygian faunas from Argentina have been improved in last years, especially those related to morphology and alpha taxonomy. However, other issues such as phylogeny and biogeography, are unknown or on its beginning.
