Anzu is a monospecific genus of caenagnathid dinosaur from North Dakota and Montana that lived during the Late Cretaceous in what is now the Hell Creek Formation. The type species and only species, Anzu wyliei is known from numerous skeletons that preserve cranial and postcranial elements. Anzu had feathers and looked like a large bird, like other dinosaurs in the group oviraptor. It was an omnivore, eating small animals and plants which it would grab with sharp claws. It also used its claws to defend itself and its babies, which it took care of after they hatched. Anzu measured about 3.5 metres (11 ft) long, up to 1.8 metres (5.9 ft) tall at the hips and 200 kilograms (440 lb) to 300 kilograms (660 lb) in weight, and was the largest North American oviraptorosaur, though the Mongolian genus Gigantoraptor was larger than Anzu.
