Just like Yutyrannus, Beipiaosaurus was a coelurosaur of giant proportions. Being the largest feathered dinosaur so far discovered is not really an honor, but certainly could be considered one. Beipiaosaurus does still have the honor of being the largest herbivorous feathered dinosaur. At 2.2 m in length, Yutyrannus measured 9 m, was a fairly good meal for its contemporary. Beipiaosaurus was kind of a big turkey dinner also. The caudal vertebrae were fused into a pygostyle. It was a big-headed turkey though, with the skull as long as the thigh.
