The Western Interior Seaway divided North America during the Cretaceous and was host to a dizzying array of creatures including marine reptiles like Tylosaurus, Elasmosaurus and Dolichorhynchops. The largest turtle ever, Archelon, the huge fish Xiphactinus, the flightless bird Hesperornis and many ammonites also lived there.
