在堪萨斯州加内特附近上宾夕法尼亚（密苏里州）斯坦顿组著名的、化石丰富的地区，发现了一种新的、小型的盘龙——Ianthasaurus hardestii。它由一个部分的、半铰接的骨架和至少三个其他个体的分散的元素来代表。小型食虫龙拥有许多原始盘龙的特征，但也与大型的早二叠纪食草动物埃达龙有一些共同的衍生特征，这证明了它被纳入埃达龙科，并被认为是该群体中最古老、最原始的成员。
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.
