Washington, USA: If you're a dinosaur with a nickname as funky as "the chicken from hell," you had better be able to back it up.
A dinosaur called Anzu wyliei that scientists identified on Wednesday from fossils found in North Dakota and South Dakota does just that. It had a head shaped like a bird's, a toothless beak, an odd crest on its cranium, hands with big sharp claws, long legs for fast running and was probably covered in feathers.
