The Coelurosaurs were large for their kind, since some of them could reach 3 meters long. They lived between the Middle Triassic and the Early Jurassic.
Coelurosaur never appeared in the original Walking with Dinosaurs series.
In Sea Monsters: A Walking with Dinosaurs Trilogy, two Coelurosaurs prowled the beaches of the Sixth Deadliest Sea, although they looked almost exactly like Coelophysis in the show. In fact, they reused the Coelophysis model, and just changed the skin of the animal.
