T. H. Huxley 18701. The dorsal vertebræ have amphicœlous or opisthocœlous centra. They are provided with capitular and tubercular transverse processes, the latter being much the longer.
2. The number of the vertebræ which enter into the sacrum does not fall below two, and may be as many as six.
3. The chevron bones are attached intervertebrally, and their rami are united at their vertebral ends by a bar of bone.
4. The anterior vertebral ribs have distinct capitula and tubercula.
5. The skull is modelled upon the Lacertilian, not on the Crocodilian type. There is a bony sclerotic ring.
6. The teeth are not ankylosed to the jaws, and may be lodged in distinct sockets. They appear to be present only in the præmaxillæ, maxillæ, and dentary portions of the mandible.
7. The scapula is vertically elongated; the coracoid is short, and has a rounded and undivided margin. There is no clavicle.
8. The crest of the ilium is prolonged both in front of and behind the acetabulum; and the part which roofs over the latter cavity forms a wide arch, the inner wall of the acetabulum having been formed by membrane, as in birds.
9. The ischium and pubis are much elongated.
10. The femur has a strong inner trochanter; and there is a crest on the ventral face of the outer condyle, which passes between the tibia and the fibula, as in birds.
11. The tibia is shorter than the femur. Its proximal end is produced anteriorly into a strong crest, which is bent outwardly, or towards the fibular side.
12. The astragalus is like that of a bird; and the digits of the pes are terminated by strong and curved ungual phalanges.
E. D. Cope 1870Limbs ambulatory or prehensile. Ilium horizontal,supporting a long sacrum of five or six vertebrae the anterior derived from the lumbar series. The acetabulum thrown forwards, and not complete,but perforate. Ischium long longitudinal, posterior, supporting the pubis in front on a process. Ribs free, double headed. Neural arches united by suture; chevron bones present.
K. A. v. Zittel 1890Körper eidechsenartig oder vogelähnlich, lang geschwänzt, meist von ansehnlicher, zuweilen sogar von gigantischer Grösse. Wirbel cavernös, hohl oder massiv; opisthocöl, platycöl oder amphicöl. Sacrum in der Regel aus drei bis sechs (ausnahmsweise aus zwei oder mehr als sechs) Wirbeln bestehend. Rumpfrippen zweiköpfig. Bauchrippen zuweilen vorhanden. Zwischenkiefer getrennt. Quadratbein unbeweglich , stark vorragend. Obere und seitliche Schläfengruben knöchern umgrenzt. Zähne mit zusammengedrückter, vorn und hinten mehr oder weniger zugeschärfter Krone, in Alveolen oder Alveolarrinnen eingefügt. Brustbein unvollständig verknöchert. Scapula sehr gross, Coracoid klein, scheibenförmig, ohne Procoracoid. Ileum nach vorn und hinten verlängert. Sitzbeine lang, schlank, in der Symphyse verbunden. Pubis nach vorn gerichtet, zuweilen mit einem dünnen, nach hinten gewendetem, dem Ischium parallelen Postpubis. Vorderbeine kürzer als Hinterbeine. Zehen mit Krallen oder Hufen. Die langen Knochen solid oder hohl. Haut nackt oder mit einem aus knöchernen Platten oder Stacheln bestehenden Panzer.
H. Gadow 1898Stereospondylous. Quadrate fixed. Ribs with capitulum and tuberculum. Limbs terrestrial. With distal ischiadic syndesmosis. Ilium horizontally elongated. With sternum.
H. Gadow 1901Mesozoic, long-tailed, toothed reptiles, with distal ischiadic symphysis, terrestrial limbs, large fixed quadrate bones and bifurcated ribs.
B. F. Nopcsa 1901Hosszufarku test; az üres cavernös vagy tömör csigolyák alakja biconcav platycöl vagy opisthocöl. A sacrum 2–6 csigolyából áll, a valódi bordák kétfejnek, mind a két foraiuen temporale csonttal van körülvéve, foguk alveolákban. A sternum tökéletlenül csontosodott, a scapula nagy, a coracoid kicsiny, korongalaku. Praecoracoid és clavicula hiányzanak. A nagy ilium úgy elore, mint hátra meg van nyújtva; a hosszú karcsú ischium a symphysisben össze van kötve. Pubis elre vagy hátra irányított, a mells lábak általában ríividebbek, mint a hátsók; az ujjak karmokkal vagy patákkal vannak cllátva. Börük lágy vagy pánczélozott.

[Long-tailed body; the shape of empty cavernous or solid vertebrae is biconcave, platycoelous or opisthocoelous. The sacrum consists of 2 to 6 vertebrae, the real ribs are surrounded by two heads, both foraiuen temporale bones, their teeth in alveoli. The sternum is imperfectly ossified, the scapula is large, the coracoid is small, disc-shaped. Praecoracoid and clavicula are missing. The great ilium is stretched forward as well as backward; the long slender ischium is connected in the symphysis. Pubis directed forward or backward, the forelegs usually shorter than the hindquarters; the fingers are clapped with claws or hooves. Their skin is soft or armored.]
B. F. Nopcsa 1928Long necked, originally bipedal Archosauria with numerous cervicals, with thecodont teeth, with prelacrymal fossa, reduced scapular arch and without humeral foramina; upper part of ilium expanded at both ends, ventral pelvic elements more or less elongated; acetabulum perforated; pineal foramen never present.
