Diagnosis

E. D. Cope 1869II. Teeth in a single row, cutting ; three digit bearing metatarsals.
T. H. Huxley 18701. The maxillary and mandibular teeth have obtuse subtriangular crowns; the surface of the enamel being ridged on one or both sides. The crowns of the teeth are worn down flat by mastication.
2. The anterior prolongation of the ilium is more slender than the posterior.
3. The rami of the mandible unite in an excavated edentulous symphysis, which receives an edentulous prolongation of the præmaxillæ.
4. The proximal end of the femur is as in the Scelidosauridæ.
5. There is no dermal armour.
L. Dollo 1882A single row of teeth. Three functional digits in the pes. Two symmetrical sternal plates.
K. A. v. Zittel 1890Zwischenkiefer zahnlos. Rückenwirbel platycöl. Postpubis unvollständig verknöchert, nicht bis zum Ende des Ischium reichend. Erste Zehe des Vorder/usses zu einem kräftigen Dorn umgestaltet, kürzer als fünfte Zehe. Hinterfuss dreizehig. Femur mit kammartig vorspringendem vierten Trochanter. Nur eine
funktionierev/le Reihe von Zähnen im Oberkiefer.
R. S. Lull 1924Toothless prcmaxilla ; anterior vertebrae opisthoccelous; sacrals coössified; postpubis very slender and shorter than ischium; sternum bony; femur longer than tibia; hand five-fingered, with spike-like pollex; foot four-toed, only ii, iii, and iv functional, as shown by associated footprints; Comanchian.
