Coelophysis is one of the best known Triassic dinosaurs, due in large part to the hundreds of complete skeletons discovered in New Mexico in 1947.

It is a slimly built running hunter with a long skull and neck, a lightweight body and a long tail. Because of its small size, Coelophysis probably traveled and hunted in herds.
