Ostracods from Río Salí Formation (Upper Miocene), near to Raco, Tucumán province, Argentina

Abstract

“Ostracods from Río Salí Formation (Upper Miocene), near to Raco, Tucumán province, Argentina”. Are described ostracod fauna from the Río Salí Formation (Upper Miocene) for the first time from Tucumán province. This fauna is represented by four species of non-marine ostracods: Darwinula stevensoni Brady y Robertson, Penthesilenula incae Delacheaux, Vestalenula sp. and Candona sp. This assemblage would indicate a developed in oligo to mesohaline, shallow lake, with clear waters, and low energy current, under a tropical to subtropical climate. These conclusions agree with the lithological data and provide some others details of paleoenvironmental conditions.
