The Hesperornis was a bird that lived during the Upper Cretaceous period. It was about 6 feet tall, had a long body and neck, and a long bill with teeth. The feet were webbed. The bird could not fly. It was an excellent diver and swimmer and caught fish to eat. Skeletons of these birds have been found in England and in the United States, especially in Kansas.
