Koskinonodon is regarded as a metoposaurid temnospondyl amphibian,‭ ‬which means that it is closest to genera such as Metoposaurus and Apachesaurus.‭ ‬These temnopondyls are noted for having eyes that were situated in a more forward position on their skulls than the eyes of other similar temnospondyl groups.‭ ‬Also like its relative genera,‭ ‬Koskinonodon seems to have been more at‭ ‬home in the water where it probably hunted for fish and possibly other amphibians.‭ ‬The limbs are generally not that well supported for terrestrial locomotion,‭ ‬and the presence of a lateral line formed by sensory sulci would have detected changes in water pressure,‭ ‬allowing them to pick up upon the movements of nearby swimming animals.
