Resumen
First fossil records of silversides (Teleostei: Atheriniformes) from the Middle Pleistoceneof Buenos Aires province, Argentina. This paper presents the fossil remains of silversides recovered insedimentary sequences corresponding to Centinela del Mar district Bonaerian Stage-Age (Middle Pleistocene),Buenos Aires province, Argentina. The few only previously described fossil silversides are restricted to threeChilean and Argentinean Miocene localities. The silversides studied here present several diagnostic osteologicalcharacters that allow us to refer the remains to the genus Odontesthes. These records give us new data on thecomposition of the pleistocenic ictiofaunas of Argentina, besides representing the first fossil records of silversidesfrom the Pampean region.
