Comahuesuchus is a notosuchian crocodile that lived in South America during the late Cretaceous period. The description of Anatosuchus in 2003 led to the idea that Anatosuchus and Comahuesuchus were close relatives, however a 2006 paper by Andrade, Bertini and Pinheiro came to the conclusion that they were not closely related. Instead a possible close relative of Comahuesuchus is the genus Mariliasuchus.
