is a genus of proterochampsian archosauromorph that lived in South
America during the Triassic. With known skull sizes ranging up to
twenty-six centimetres in length, Chanaresuchus
would had the
potential to have been a moderately sized predator, but nothing near
the scale of large rauisuchians
such as Saurosuchus.
however would have still been a threat to smaller animals, and
perhaps even primitive dinosaurs and there immediate ancestors.
Chanaresuchus was named after the Chañares Formation where the first ever fossils of the genus were found, but since this time further fossils are now also known from Brazil. A former species of Chanaresuchus, C. ischigualastensis, has now been re-described as a new genus called Pseudochampsa.
