Common name: Hesperornis
Species: Hesperornis avenatantes
Time: Late Cretaceous
Possessing the appearance of a half-duck/half-dinosaur, Hesperornis is a medium-sized, fish-eating bird, common in the rivers and lakes of the island. It would be about two-thirds the height of a human if it stood tall, but it rarely does. Hesperornis spends most of its time gliding along the surface of the water, where it is much more maneuverable. Hesperornis is barely a threat to any land-dwelling creature, as its legs are too short for it to move around effectively, but it is surprisingly fast in the water. It can easily hunt down fish and other small water-dwelling creatures.
Not particularly useful for hunting, and not being affectionate, Hesperornis is primarily kept for the eggs it produces after consuming much fish. When rendered correctly, the eggs separate into two useful substances. One is a protein substance that is high in calories, and the other is an oily liquid that is effectively the same as the Oil found in the ocean!
