Chanaresuchus is an extinct genus of proterochampsian archosauriform. It was of modest size for a proterochampsian, being on average just over a meter in length. Fossils are known from the Middle and Late Triassic of La Rioja Provence, Argentina. Two species are currently known: the type species Chanaresuchus bonapartei was named from the Ladinian-age Chañares Formation in 1971 and the species Chanaresuchus ischigualastensis was named in 2012 from the late Carnian-age Ischigualasto Formation. Chanaresuchus appears to be one of the most common archosauriforms from the Chanares 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 was originally classified in the family Proterochampsidae, although it has been placed in the family Rhadinosuchidae in more recent studies (both families belong to the larger group Proterochampsia).
