Diagnosis
Reference  Diagnosis  

E. D. Cope 1869 (Goniopoda)  Proximal tarsal bones distinct from tibia ; the latter closely embraced by the much enlarged astragalus, on its inferior and anterior faces, forming an immoveable articulation. Astragalus, with an extensive anterior articular condyle below, above in contact with the fibula, which is much reduced, especially distally. Anterior part of the ilium dilated, and platelike.  
K. A. v. Zittel 1890  Zwischenkiefer bezahnt. Zähne zugespitzt, dolchförmig, seitlich zusammengedrückt, zurück gekrümmt, am vorderen oder hinteren oder an beiden Rändern gekerbt. Nasenlöcher gross, seitlich, mehr oder weniger weit nach vorn gerückt. Grosse präorbitale Durchbruchsöffnungen vor den Augenhöhlen. Wir bel massiv oder hohl, die vorderen opisthocöl oder amphicöl. Extremitätenknochen hohl. Vorderbeine beträchtlich kürzer als die hinteren. Füsse digitigrad; Zehen (fünf bis drei) meist ungleich lang, mit spitzen, gekrümmten Klauen. Schambeine schlank, nach vorn gerichtet, distal verschmolzen, verbreitert und meist etwas nach hinten verlängert. Postpubis fehlt. Femur mit innerem Trochanter. Astragalus in der Regel mit aufsteigendem Fortsatz.  
H. Gadow 1898  Pubes simple, with symphysis. Premaxilla with teeth. Carnivorous. Forelimbs shorter than hindlimbs. Metatarsals elongated. Digitigrade.  
H. Gadow 1901  Pubes simple, with symphysis. Premaxillae with teeth. Digitigrade. Carnivorous.  
R. S. Lull 1924  Bipedal dinosaurs, with birdlike raptorial feet, the clawed fore limbs becoming proportionately smaller as their evolution progressed; teeth laterally compressed, often serrate; pubis having footlike expansion at symphysis in forms above the Trias, those without it being included in Huene's Pachypodosauria.  
S. J. Nesbitt 2011  The most inclusive clade containing Passer domesticus Linnaeus, 1758, but not Saltasaurus loricatus Bonaparte and Powell, 1980
