Abstract: A new, small pelycosaur, Ianthasaurus hardestii, has been discovered in the well-known, richly fossiliferous locality in the Upper Pennsylvanian (Missourian) Stanton Formation, near Garnett, Kansas. It is represented by a partial, semi-articulated skeleton and scattered elements of at least three other individuals. The small, insectivorous Ianthasaurus possesses a number of primitive pelycosaurian features but also shares several derived characters with the large Early Permian herbivore Edaphosaurus, justifying its inclusion in the family Edaphosauridae and its recognition as the oldest and most primitive member of that group.
