Chanaresuchus is an extinct genus of proterochampsid archosauriform. It was of modest size for a proterochampsian, being on average just over a meter in length. The type species is Chanaresuchus bonapartei was named in 1971. Its fossils were found in from the early Carnian-age Chañares Formation in La Rioja Province, Argentina .[1]Chanaresuchus appears to be one of the most common archosauriforms from the Chañares Formation due to the abundance of specimens referred to the genus. Much of the material has been found by the La Plata-Harvard expedition of 1964-65. Chanaresuchus is the most well-described proterochampsid in the subfamily Rhadinosuchinae.
A second proposed species, C. ischigualastensis, was named in 2012 from the late Carnian-age Ischigualasto Formation,[2] was briefly assigned to Chanaresuchus before being moved to its own genus Pseudochampsa in 2014.[3]C. bonapartei has been reported from the Santa Maria Formation in Brazil,[4] but the Brazilian fossils were given their own genus Kuruxuchampsa in 2023.[5]
