About Hesperornis

One of the largest birds to have lived during the age of the dinosaurs, the Hesperornis lived about 70 Million years ago. Hesperornis evolved from flying birds, but like modern day penguins, Hesperornis had lost the ability to fly. Instead, it lived the life of a sea animal. A talented swimmer, Hesperornis spent its day cooling in the sea breeze and hunting fish and other sea animals. Hesperornis was about the size of a full grown human.
