Coelophysis bauri (Cope1889, Colbert 1989) Norian, Late Triassic ~210mya, 3 m in length, was derived from a sister to Tawa and phylogenetically preceded theropod dinosaurs, including Guanlong and Aurornis in the lineage of birds.
Distinct from Tawa, the skull of Coelophysis had a longer rostrum. The forelimb was more robust. The pelvis was elongated in every direction. The ilium has a larger anterior and posterior process with more sacrals between them. The pubis extended far anteroventrally and the ischium was likewise elongated. The hind limb was relatively shorter and the pes was smaller with more robust digits. Pedal digit 1 was a vestige. So was pedal digit 5.
