Resumen:
Abstract. This study analyzes a collection of fossil mammals from the Salicas Formation in the El Degolladito area, La Rioja Province, Argentina.
The materials reported herein were recovered from two sites (site 1 and site 2) and are: Macrochorobates Scillato-Yané, Chasicotatus

(Lagostomopsis) Kraglievich, and Octodontidae indet. (Rodentia, Caviomorpha). This new mammalian assemblage, together with one previously
recorded, has several taxa in common with mammalian associations from Central Argentina (i.e., La Pampa Province). Among those
coming from Northwestern Argentina, the major affinity is with the El Jarillal Member (Chiquimil Formation) and then the Andalhuala
Formation (both in Catamarca Province). The Salicas Formation fauna is considered as latest Miocene in age until new fossil discoveries
and radioisotopic dates allow a better calibration. The fossil biota and geological data suggests that the Salicas Formation was deposited in
flatlands, under warm and dry conditions. This environment was dominated by open grasslands, with forested areas near rivers and lagoons
