It was terrestrial, living approximately 85 million years ago in the Santonian stage of the Late Cretaceous.

[5] In it, the authors suggested that the skull would have supported a short trunk, or "hog's snout" as well as fleshy upper and lower lips.

The anteriorly directed nares and the absence of a bony nasal septum (which presumably indicates cartilaginous tissue serving its place) provide evidence for a trunk-like snout, while striations on the surface of the nasal bones and the lower jaw most likely acted as attachment points for the nasolabial muscles and the depressor muscle, respectively.

[6] Additionally, the authors suggested that a lateral rim on the dentary as well as numerous aligned neurovascular foramina are evidence of soft cheek-like muscular tissue.

[5] A re-description of the skull material has since lent evidence toward minimal soft-tissue enhancement to the snout of Notosuchus.
