The Great Toothed Diver, Hesperornis regalis, an extinct
five foot long diving bird lived during the Cretaceous period - with teeth!
Hesperornis regalis did not have wings, but propelled itself with powrful
hind legs and lobed toes similar to the grebes of today. Hesperornis regalis
lived in the prehistoric North Sea, the West Siberian Sea, and the Great
American Inland Sea, preyed upon fish, crustaceans, cephalopods and mollusks
and were preyed upon by Mosasaurs.
This 9 ft Tall, 280 lb flightless, terror bird of prey was a
real predator, racing over the grassy plateaus and hills of Patagonia 30
million years ago, catching small reptiles and mammals and biting them in
half with its huge beak or just shaking them into senselessness before
ripping them to pieces!
