Hesperornis regalis

Hesperornis (meaning "western bird") is a genus of flightless aquatic birds that spanned the first half of the Campanian age of the Late Cretaceous period (83.5–78 mya). One of the lesser-known discoveries of the paleontologist O. C. Marsh in the late 19th century Bone Wars, it was an early find in the history of avian paleontology.

Hesperornis regalis. One of the strangest early finds of the Victorain Bone Wars was the discovery of toothed birds in the chalk of Western Kansas. O.C. Marsh and his crew discovered this large, flightless, diving bird which was evidently a strong swimmer based on how far from shore its fossils are found.Hesperornis ranged sea shores from Kansas to Russia and Sweden during the Late Cretaceous, spanning nearly 20 million years. The beaches of Kansas aren't what they used to be: when Hesperornis lived, western Kansas enjoyed a climate not unlike that of modern Florida. Alaska looked more like Oregon, and Arctic ice caps had not yet formed.Hesperornis regalis Marsh, 1872: Některá data mohou pocházet z datové položky.
