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 and Rio Grande do Sul (geoparque Paleorrota), Brazil. The type species and only currently known species is Chanaresuchus bonapartei was named from the Ladinian-age Chañares Formation in 1971. A second species C. ischigualastensis named in 2012 from the late Carnian-age Ischigualasto Formation, was briefly assigned to Chanaresuchus before being moved to its own genus Pseudochampsa in 2014. C. bonapartei has recently been found in the Carnian Santa Maria Formation in Brazil. Chanaresuchus appears to be one of the most common archosauriforms from the
