Diagnosis
ReferenceDiagnosis
J. L. Benedetto 1973Saurischians of carnivorous habits, moderate size and bipedal posture. Presacral
vertebrae tall, with anteroposteriorly short neural spines; ilium shorter than in Prosauropoda, tall, with anterior spine short and posterior spine truncated or rounded. Acetabular cavity strongly excavated and supraacetabular crest prominent; acetabulum with incipient aperture. Pubis proportionally long, with development of a distal “foot”, expanded sagittally and laterally compressed. Ischium much shorter than the pubis, with slender distal elongation, without expansion. Sacrum with three vertebrae. Femur sigmoid, slender, with the fourth trochanter situated above the midshaft. Slender tibia, with little torsion between its ends, little expanded distally and with descending posterior process. Astragalus and calcaneum of prosauropod type, the former strongly connected to the tibia. Pes with elongate metatarsals, symmetrical around digit III; metatarsals I and V narrower than the others, but longer and of approximately the same length; elongate phalanges. Forelimb with tendency toward reduction.
