Anzu is a fairly large caenagnathid oviraptorosaurian dinosaur that grew to nearly 4 m in length, and weighed 200-300 kg. It was a bipedal dinosaur and was covered in feathers, with a large sloping crest atop its head. Typical of oviraptorosaurs, Anzu had a short toothless beak, an adaptation that suggests it was most likely herbivorous or possibly omnivorous.
