Coelophysis - Coelophysis among Araucaria - Artist's view of three coelophysis, one male and two females, in a pine forest of the genus araucaria. Coelophysis was one of the first hunters dinosaurs. He lived at the end of the Upper Triassic between 230 and 205 million years BC. It could measure up to 3 metres in length and 1.70 metres in height. Coelophysis most likely hunted in packs. Three carnivorous Coelophysis, one male and two females, walk among a forest of prehistoric Araucaria evergreens. Coelophysis is one of the earliest known dinosaurs, emerging about 215 million years ago during the late Triassic period. It stood only as tall as a man's hip and probably was a fast runner
