F. v. Huene 1948	Beginning with semiquadrupedal forms; organized like contemporary Carnosauria, but not predaceous teeth, skull smaller, neck longer; gap between supraoccipital and parietal; 10 elongated cervicals, 15 dorsals, 3 sacrals; scapula broader than in Carnosauria; rudiments of secondary shoulder girdle; ilium with small anterior spine; broad pubic plate; ischium with peduncle; femur longer than tibia. Only Triassic.
J. F. Bonaparte 1978	Restringidos al Triásico superior, de hábitos cuadrupedales algunos, y con tendencia al bipedalismo otros. Principalmente herbívoros.
