River canyon, in the province of
Mendoza (central-western Argentina). It comes stratigraphically from the Aisol Formation, which is ascribed to the middle to late Miocene. Due to its characteristics, it was assigned to: Pterocnemia cf. P. mesopotamica (= Rhea cf. R. mesopotamica). In case of belonging to this species, its biochron begins to extend into the past, being then understood from the late Miocene (Huayquerian Age) to the Middle Miocene (Friasense Age).
