 Many of these features appear more derived in "L. paludis", leading some to consider it to be the more derived of the two species.In its earliest descriptions, "Limnoscelis" was identified as an early reptile, thought to be closely related to the Captorhinidae or Pareiasauridae based on its flat occiput, as well as its large upper incisors and broad parareptile-like neural arches.However, Williston noted enough differences from these groups to place "Limnoscelis" within its own subfamily, the Limnoscelidae, which would later be erected as its own family.
