Deadly X fish and Hesperornis | Xiphactinus #prehistoricplanet
Xiphactinus was one of the largest bony fish ever to have lived and was truly a monster. It ranged in size from 15-20 feet (4.5 - 6m) and would have looked like a toothy, oversized tarpon. It lived during the Cretaceous period from about 112 million years ago up to the Cretaceous-Palaeogene Extinction, 65 million years ago.
Hesperornis (meaning "western bird") is a genus of cormorant-like bird "and" dinosaur that spanned throughout the Campanian age, and possibly even up to the early Maastrichtian age, of the Late Cretaceous period.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. Locations for Hesperornis fossils include the Late Cretaceous marine limestones from Kansas and the marine shales from Canada. Nine species are recognised, eight of which have been recovered from rocks in North America and one from Russia.
