Hesperornis



Scientific Classification
  Kingdom Animalia
  Phylum Chordata
  Class Aves
  Subclass Hesperornithes
  Order Hesperornithiformes
  Family Hesperornithidae
  Genus Hesperornis
Hesperornis is an extinct genus of birds that lived during the late Cretaceous period between about 89 million and 65 million years ago.

Hesperornis were flightless and aquatic. They were large, growing to about 6½ feet (2 meters) in length. Their wings were greatly reduced, and instead they swam using their powerful hind legs (its legs were in fact so widely splayed out that, Hersperornis may not have been able to stand or walk on land). Their beaks were equipped with teeth, which would have helped them with holding on to fish, as well as dealing with hard-shelled prey such as molluscs and crustaceans.

Hesperornis fossils were first found by Othniel C. Marsh, who also named the genus in 1872. Fossils of these birds are particularly found in Kansas in the United States, and also in Canada, however it is thought likely that they were quite widespread throughout the Northern hemisphere.
