 The ganoid scales found in the general area where "Hesperosuchus" was found belong to freshwater fish of the Triassic period, belonging to the genus "Semionolus" or "Lepidolus", which lived in shallow lakes and streams.The phytosaur teeth and small sterospondyl vertebrae found near "Hesperosuchus" support the presence of lakes or streams crossing a flood plain.Also the many small teeth found, which some, belong to amphibians of the Triassic period supports the occupying of near water habitats.
