Chanaresuchus
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.
Chanaresuchus
however would have still been a threat to smaller animals, and
perhaps even primitive dinosaurs and there immediate ancestors.
Chanaresuchus
was named after the Cha�ares 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.
