K. A. v. Zittel 1890  Zwischenkiefer bezahnt. Zähne spateiförmig, am Vorder und Hinterrand zugeschärft, aber nicht gekerbt. Nasenlöcher
verlängert. Vor den Augenhöhlen eine grosse präorbitale Oeffnung. Hals und vordere Rückenwirbel opisthocöl, die übrigen amphicöl oder platycöl. Centra der Rücken, zuweilen auch der Sacralwirbel mit seitlichen Hohlräumen. Extremitätenknochen massiv. Femur ohne vorspringenden inneren Trochanter. Vorderbeine wenig kürzer als Hinterbeine. Alle vier Füsse plantigrad, fünfzehig. Schambein massig lang, breit, distal knorpelig verbunden. Postpubis fehlt.  
H. Gadow 1898  Pubes simple, with symphysis. Premaxilla with teeth. Fore and hindlimbs pentadactyle, plantigrade.  
H. Gadow 1901  Pubes simple, with symphysis. Premaxillae with teeth. Plantigrade.  
R. S. Lull 1924  Amphibious, plantfeeding dinosaurs, with relatively very small head, bearing one, rarely two, preorbital fenestrae; jaws partially or wholly beset with spatulate or styliform teeth; most of presacral vertebrae opisthocoelous, posterior dorsals and caudals being as a rule amphicoelous or amphiplatyan, rarely procoelous; vertebrae generally cavernous or with lateral cavities, pleurocoeles, in central; neural canal greatly enlarged in sacrum, somewhat as in Stegosaurus (see below); limb bones massive, probably without medullary cavity; fore limbs generally shorter, but sometimes fully equaling or even exceeding hind in length; feet semiplantigrade, fivetoed, but with reduced phalanges on external side; unguals strongly compressed, but massive.  
B. F. Nopcsa 1928  omnivorous; quadrupedal; cervical and dorsal vertebrae opisthocoelous and with platelike buttresses; os penis present.  
F. v. Huene 1948  Secondarily quadrupedal animals; solid structure of leg bones; cavernous vertebrae; small skull; elongated neck, shortened body; manus digitigrade, pes semiplantigrade; lower leg shortened; strong and long tail, often with whiplike end. Short temporal region in skull; orbit in high position; enlarged nasal openings in backward position, preorbit large; teeh spatulate or boltlike; complicated laminar structure of vertebrae; cervicals much elongated; shoulder girdle shifted backward; two large sternal plates; ilium with large anterior and without posterior process. Large animals. Lower Jurassic to Upper Cretaceous.  
J. F. Bonaparte 1978  Jurásico y Cretácico; hábitos cuadrupedales, formas gigantescas, herbívoros.
