Coelophysis was one of the first agile meat-eating dinosaurs. This relatively small theropod scurried around what is now New Mexico during the Triassic Period, at the dawn of the age of the dinosaurs, 200 million years ago. History: Coelophysis was first discovered and described in the 1880s based on some partial fossils. It remained poorly known until 1947, when hundreds of complete and near-complete skeletons were discovered at Ghost Ranch, New Mexico, USA. Excavated and studied by the American Museum of Natural History, this ‘graveyard’ of specimens contained both young and old individuals. Scientific Name: Coelophysis bauri Characteristics: As this Coelophysis toy shows, this dinosaur is a delicately built, two-legged carnivore with slender legs and three-toed feet. It had sharp, serrated teeth and was roughly 10 ft long, from head to tail. Size: This slender Coelophysis toy model is 7.25 inches long and 2.5 inches high. The Coelophysis is part of the Wild Safari.
