Genus information

Coelophysis is a small carnivore from the Late Triassic and Early Jurassic epoch of North America and Africa. They were very slender and lightly built dinosaurs with long, S-shaped necks and short arms. Due to its body was very light, it was probably a fast dinosaur, being able to cover a lot of ground to scavenge for food. Coelophysis are believed to have lived in large packs; especially in drier seasons. Huge numbers of Coelophysis have been found together in several places in North America and Africa. There is a clear difference in sexual dimorphism; males were slight robust form while females were more gracile. Coelophysis lived in floodplains with clear variations in seasons.
