       In‭ ‬1941‭ ‬an alligator specimen from the Green River Formation was interpreted as being a new species of Hassiacosuchus by C.‭ ‬C.‭ ‬Mook.‭ ‬However a later‭ ‬1967‭ ‬study by Wassersug and Hecht found the remains of the second species actually belonged within the Procaimanoidea genus,‭ ‬and as such‭ ‬the second species of Hassiacosuchus became the second species of Procaimanoidea.‭ ‬This also makes Hassiacosuchus a distinctly European genus,‭ ‬however its future as a distinct genus is in doubt.‭ ‬Later studies have suggested that Hassiacosuchus may in fact belong within another North American genus called Allognathosuchus,‭ ‬although in‭ ‬2004‭ ‬another study by Christopher Brochu has led to the recommendation that Hassiacosuchus remain a distinct genus.
