Sister groups to "Saltoposuchus" include "Gracilisuchus", "Hesperosuchus", "Dromicosuchus", "Dibothrosuchus", "Terrestrisuchus", "Litargosuchus", "Kayentasuchus". These genus are found in the late Triassic to the earlier Jurassic eras. All of these genus are part of the "Sphenosuchia" clade and they all have similar morphology and stature. "Sphenosuchia" are ancestors to crocodyliformes, which constitute modern crocodilians. Modern crocodylia reacquired semi-aquatic life style. Research has disputed the reasoning for how crocodyliformes reacquired semi-aquatic traits, and the forefront explanation the changes in osteoderm and rib morphology over crocodylomorph evolution affected the stiffness of the vertebral columns, which would allow for better movement in semi-aquatic environments.
