Hesperosuchus is an extinct genus of crocodylomorph reptile that contains a single species, Hesperosuchus agilis. Remains of this pseudosuchian have been found in Late Triassic (Carnian) strata from Arizona and New Mexico. Hesperosuchus was once believed to an ancestor of later carnosaurian dinosaurs due to similarities in skull and neck anatomy along with the presence of hollow bones. Now with further findings and research, Hesperosuchus is now known to be closer related to not dinosaurs but crocodilians instead. At only about 4 to 5 feet in length, Hesperosuchus is a relatively small and lightly built pseudosuchian.
