Late Triassic 203 to 196 million years ago old.

Coelophysis is a genus of small, carnivorous theropod dinosaur that lived during the Late Triassic period, around 203 to 196 million years ago. The name Coelophysis means “hollow form” and refers to the hollow bones found in this dinosaur’s skeleton. It was a bipedal dinosaur with a long, slender body, a long neck, and a narrow head with sharp teeth. Coelophysis is one of the earliest known dinosaurs and is considered an important species for understanding the evolution and diversity of dinosaurs during the Mesozoic Era.

Coelophysis fossils have been found in North America, specifically in the southwestern United States, including New Mexico and Arizona. One of the most famous fossil sites for Coelophysis is Ghost Ranch in New Mexico, where numerous skeletons have been discovered in a mass death assemblage. These fossils have provided valuable information about the anatomy, behavior, and ecology of Coelophysis.

Studies of Coelophysis fossils have revealed that it was a fast and agile predator that likely hunted small animals and insects. Its lightweight skeleton and long legs suggest that it was adapted for swift movement on land. The discovery of juvenile Coelophysis skeletons preserved with adult individuals at Ghost Ranch has also shed light on its social behavior and possible pack-hunting tendencies.
