Registros fósiles de “viejas del agua” (Teleostei: Siluriformes) del Pleistoceno superior de la localidad de Salto, Buenos Aires, Argentina

Abstract

In this work we give notice of new materials assigned to Siluriformes of the Loricariidae family, recovered in lacustrine sedimentary sequences corresponding to the Lujanian Stage-Age (Upper Pleistocene) at the Salto- Arrecifes River, Salto District, Province of Buenos Aires, Argentina. A part of these materials is morphologically alike to structures of the Hypostomus genus. The findings here informed allow confirming the presence of large Loricariidae in Pampean sedimentary sequences of Lujanian Age, in the north of Buenos Aires Province.
