Here, we present a fossil bird assemblage coming from levels of the Las Flores Formation, in area Puchuzum Calingasta Valley. The mammals represent Huayquerian SALMA within late Miocene. We report for first time fauna central Argentina. avifauna is composed an indeterminate anatid, new tadornine duck, palaelodid flamingo, grebe, coot genus Fulica and heron recurvirostrid, which constitute typical waterbird assemblage. This was found beds interpreted as being fluvial system with floodplains that represented ephemeral lake ('Puchuzum lake'), exposed to seasonal droughts. It possible Pliocene arid pulse occurred Argentina may be regarded cause extinction some members avifauna, particularly those palaelodids.
