Cunampaia is a dubious genus of extinct mesoeucrocodylian. Fossils have been found from the Divisadero Largo Formation of Mendoza Province, Argentina , and date back to the Divisaderan to Tinguirirican regional South American Land Mammal Age of the Late Eocene epoch.[1]

Description

Originally it was regarded as a gruiform bird, being only recently reassigned as a crocodylomorph.[2] In 1968 it was placed in its own family, Cunampaiidae, which falls within the suborder Cariamae.[3] Despite this classification, it has frequently been referred to as a phorusrhacid.[4]

Due to the lack of autapomorphies associated with the genus, Cunampaia is now considered to be a nomen dubium. As a result of this, its position is indeterminate within Mesoeucrocodylia.
