Both lived in the Late Triassic, among the earliest dinosaurs, but in different regions: Coelophysis in North America, Plateosaurus in Europe.
Plateosaurus (8 m, ~700 kg) was much larger than Coelophysis (3 m, ~20 kg).
Plateosaurus was an early herbivore (prosauropod); Coelophysis was a slender carnivore.
Mass death assemblages have been found for both โ Coelophysis at Ghost Ranch, Plateosaurus in Germany โ suggesting gregarious behavior.
Both represent the initial radiation of dinosaurs before they dominated the Mesozoic world.
