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 hind-limbs pentadactyle, plantigrade.
H. Gadow 1901	Pubes simple, with symphysis. Premaxillae with teeth. Plantigrade.
B. F. Nopcsa 1901	Kis fogak, postorbitale hiányik, intermaxillare fogakkal, nagy praeorbitalis nyilás. A nyak és hátcsigolyák opistocölek, a többiek platycölek. A csigolyatcstek, néha a sacrum is, üresek vagy cavernösek; a hosszú csontok tömörek. Femur kiálló belsö trochanter nélkül. A mellsö lábak valamivel rövidebbek, mint a hátulsók. Plantigrad lábuk 5 ujju. Pubis hosszukás, széles, távolabbi végei porczosan összekötve. Postpubis nincs. (Zittel szerint.) [Small teeth, postorbital missing, intermaxillary teeth, large preorbital opening. The neck and back vertebrae are opistocoelous, the others are platycoelous. The vertebrae, sometimes the sacrum, are empty or cavernous; the long bones are solid. Femur without protruding internal trochanter. The forelegs are slightly shorter than the hind legs. Their feet plantigrade, 5 toes. Pubis elongated, broad, distal ends cartilaginously connected. There is no post-pubis. (According to Zittel.)]
R. S. Lull 1924	Amphibious, plant-feeding 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 semi-plantigrade, five-toed, 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 plate-like buttresses; os penis present.
E. Perrier 1928	Taille très grande; cou et tête très allongés; tête extrêmement petite ; prémaxillaires dentés; membres dressés; pieds petits, plantigrades; un pubis simple avec symphyse.

Herbivores.
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 whip-like end. Short temporal region in skull; orbit in high position; enlarged nasal openings in backward position, preorbit large; teeh spatulate or bolt-like; 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.
