This illustration provided by the Carnegie Museum of Natural History Tuesday shows the dinosaur Anzu wyliei. The birdlike animal, about 7 feet tall, weighed an estimated 500 pounds when it roamed western North America around 66-68 million years ago. Nicknamed the "chicken from hell," the creature was formally introduced with an official name to the scientific community today as scientists published a description and analysis of its anatomy.
