Though it is believed to be more often on two feet as the long slender hands looked as if it was adapted for grasping, which may have been useful for food gathering, digging or defense.

In the fronto-parietal regions of the skull, along with a flat cranial roof, marked depressions were found in the frontal and post orbital bones, in front of and lateral to the supratemporal fenestrae.

The basioccipital region is defined as typically archosaurian,[2] with a rounded condyle, a rather elongated surface above it for the medulla oblongata, and an extended ventral plate.

It can be said that both these groups were active and carnivorous as large skulls allow for wide gaping jaws to catch and attack prey.

[1] Ziphodont dentition and theropod-like pattern of linearly arranged jaw foramina of Hesperosuchus suggest a possible existence of lips that protected its teeth from the outside.

In addition, models and figures were also made by John LeGrand Lois Darling from the Museum Illustrators Corps.

[1] The exact location where the specimen was found is an area 6 miles (9.7 km) southeast of Cameron, Arizona, close to the old Tanner Crossing of the Little Colorado River.

There were many ganoid scales believed to have belonged to Triassic freshwater holostean fish, several phytosaur teeth, and many small stereospondyl vertebrae.

Northern Arizona's landscape during the Triassic period was surrounded by numerous bodies of water like lakes and streams.

The phytosaur teeth and small stereospondyl vertebrae found near Hesperosuchus support the presence of lakes or streams crossing a flood plain.

Also the many small teeth found, of which some belong to amphibians of the Triassic period, supports the occupying of near water habitats.
