Coelophysis was a small, bipedal dinosaur with a long, slender neck and tail. It had a narrow skull with a pointed snout and sharp teeth. Its arms were short, but its legs were long and powerful. Coelophysis was covered in feathers, which were probably used for insulation and display.
Coelophysis was a fast runner and could reach speeds of up to 20 miles per hour (32 kilometers per hour). It was also a good climber and could use its claws to grip branches and climb trees. Coelophysis was a carnivore and fed on insects, small reptiles, and mammals.
Coelophysis was one of the first dinosaurs to evolve. It appeared in the Late Triassic period and survived for about 10 million years. Coelophysis is known from fossils that have been found in North America, Europe, and Asia.
