Dinosaurs: Coelophysis (Hollow Form)
Last updated: 5th Jan 2024 Coelophysis was a small, meat-eating dinosaur that lived during the late Triassic period, around 228 to 200 million years ago. Known for its lightweight and agile build, Coelophysis roamed the regions that are now known as North America, particularly in areas like South Africa, USA, and Zimbabwe. Length: Coelophysis could grow up to 5-10 feet (1.5-3 meters) long, with adults coming in different sizes, often categorized into robust and graceful forms, likely indicating males and females. Coelophysis had a sleek and light body structure with long legs and a hollow bone structure, which made it a swift hunter. It had four fingers on each hand and a distinctive kinked upper jaw with a gap between its front and back teeth, similar to other members of the Ceratosaur family.

Coelophysis was a carnivore, meaning it only ate meat. Its diet included small vertebrates, reptiles, fish, and sometimes even other Coelophysis, indicating that it was a cannibal. Its small, sharp teeth were perfect for grabbing and eating its prey. Coelophysis moved on two legs and was known for its agility and speed. Its long legs and hollow bones suggest it was a fast and efficient hunter. Fossil remains of Coelophysis have been found in various parts of the world, including North America (particularly in New Mexico at Ghost Ranch), South Africa, and Zimbabwe. The large number of specimens found together suggests that Coelophysis might have hunted in packs. What is a Coelophysis?
