Occasionally interpreted as a very primitive mammal, Oligokyphus is today usually seen as a very late surviving cynodont, as well as one of the last of the non-mammalian therapsids. Still, Oligokyphus has been stated as being akin to a modern day weasel in terms of ecological niche, hunting for small animals on the ground, though it is also plausible that Oligokyphus may have also been a climber.
