I found this on the web, which may be of interest. Note that the subject is
a *saurischian*, not *ornithischian* dinosaur. I quote all the substance of
the web page:
Coelophysis was a small, lightly-built dinosaur that walked on two long legs.
It was about 9 feet long
(2.8 m). It had light, hollow bones (hence its name), a long head with dozens
of small, serrated teeth,
three clawed fingers on its hands, and a long neck.
Coelophysis was a saurischian ("lizard-hipped") dinosaur, and atheropod. Its
further classification is
disputed, but it may be aceratosaurian. It is closely related to
Rioarribasaurus (or may be the
WHEN COELOPHYSIS LIVED
Coelophysis lived in the late Triassic period.
Coelophysis was a carnivore, a meat eater. It may also have been a scavenger.
stomach remains have been found containing small reptiles, fish, and other
Coelophysis bones of different
sizes, indicating that it was a cannibal.
Coelophysis probably lived and hunted in packs; this is suggested by the
existence of fossil bonebeds of
Coelophysis (collections of many fossils of one location).
Slightly built, long legged, and very light because of its hollow
bones,Coelophysis was a very fast
bipedal runner. Dinosaur speeds are estimated using their morphology
(characteristics like leg length
and estimated body mass) and fossilized trackways.
