Ostracoda (Arthropoda, Crustacea) of limnic habitat of the Collon Cura Formation, Chubut Province, Argentina

The ostracods found in the lower beds of the Collon Cura Formation, which is exposed in northwestern Chubut province, are described. Three species are mentioned for the first time for the strata and two taxa are proposed as new: Cyprinotus australis sp. nov. and Limnocythere colloncurense sp. nov. B...

Based on the presence of the genus Cyprinotus, which up to now was only mentioned from low latitudes, the inferred paleoenvironment had temperatures near 20°C; the limnic waters were mineralized and responded to the neutral saline path with carbonates (presence of Limnocythere), sulfates and chlorates.
