Hesperornis

Hesperornis was the Late Cretaceous (85‒78 Ma) genus of flightless birds. It possessed a prolonged skull and markedly toothed beak. Legs were shifted to the back representing an adaptation for swimming and diving. Wings were stunted. Feet did not possess webs but they had rather developed flat lobes. Hesperornis preyed on fish and marine molluscs. Hesperornis' findings were recorded in North America and Ural Mts. area.
