 Alfred Sherwood Romer suggested that this might be a retention of an ancestral semiaquatic lifestyle found in amphibians, which might have also been retained in some early pelycosaurs.However, other studies have suggested a significantly more terrestrial lifestyle for "Limnoscelis", based on relatively well-ossified portions of its post-cranial skeleton.Despite its long conical teeth indicating a carnivorous diet, Williston doubted that "Limnoscelis" could have been a predator, as he believed its short, robust limbs made it too slow to pursue prey.
