bauri are also slight variations on the theropod body plan. It had only three functional digits, the fourth embedded in the flesh of the hand.Ĭoelophysis had narrow hips, forelimbs adapted for grasping, and narrow feet. Coelophysis also preserves the ancestral condition of possessing four digits on the hand (manus). bauri had a furcula (wishbone), the earliest known example in a dinosaur. The torso of Coelophysis conforms to the basic theropod body shape, but the pectoral girdle displays some interesting special characteristics: C. Despite being an early dinosaur, the evolution of the theropod body form had already advanced greatly from creatures like Herrerasaurus and Eoraptor. Coelophysis was a bipedal, carnivorous, theropod dinosaur that was a fast and agile runner. Paul (1988) estimated the weight of the gracile form at 15 kg (33 lb), and the weight of the robust form at 20 kg (44 lb).
bauri, which was a lightly built dinosaur which measured up to 3 metres (9.8 ft) in length and which was more than a meter tall at the hips. This primitive theropod is notable for being one of the most specimen-rich dinosaur genera.Ĭoelophysis is known from a number of complete fossil skeletons of the species C. Another dinosaur genus, Megapnosaurus, has also been considered to be a synonym. The names Longosaurus and Rioarribasaurus are synonymous with Coelophysis. bauri, originally given to the genus Coelurus by Edward Drinker Cope in 1887, was described by the latter in 1889.
Scattered material representing similar animals has been found worldwide in some Late Triassic and Early Jurassic formations. Coelophysis is one of the earliest known dinosaur genera. It was a small, slenderly-built, ground-dwelling, bipedal carnivore, that could grow up to 3 m (9.8 ft) long.
Coelophysis (/ˌsɛlɵˈfaɪsɨs/ or /ˌsiːlɵˈfaɪsɨs/ pron.:SEL-oh-FY-sis or SEE-low-FY-sis) is an extinct genus of coelophysid theropod dinosaur that lived approximately 203 to 196 million years ago during the latter part of the Triassic Period in what is now the southwestern United States.
