Description

Tylosaurus proriger
Named by Othniel Charles Marsh, 1872 (proriger by Edward Drinker Cope, 1869)
Diet: Piscivore and Carnivore (as fossil evidence such as its stomach content and so forth show, prey included large fish such as Xiphactinus, ammonites, the seabird Hesperornis, plesiosaurs such as Dolichorhynchops, sharks such as Cretoxyrhina and Squalicorax, turtles such as Archelon and Protostega, the giant squid Tusoteuthis, and smaller mosasaurs such as Clidastes. It may have also fed on pterosaurs such as Pteranodon, Nyctosaurus, and Geosternbergia while hunting prey by foraging underwater, much like most of today's aquatic birds. It may have also fed on dinosaurs that were swept offshore and most likely died and scavenged on the carcasses as the remains of an unnamed hadrosaur found in the Talkeetna Mountains of the Matunuska Formation, Alaska that date back less than 70 million years in the Maastrichtian age containing bitemarks made by an unnamed Tylosaurus species)
Type: Squamate (mosasauroid mosasaurid Tylosaurinae) reptile
Size: 46 feet (14 meters) long and 6.1 tons
Region: North America (Kansas, Alabama, South Dakota, Montana, Texas, and Colorado USA)
Age: Late Cretaceous (86.5 to 75 million BC; Santonian to Mid Campanian)
Rival: The Ginsu shark, Cretoxyrhina mantelli (The remains of a Tylosaurus bore bite marks made sharks, possibly by Cretoxyrhina, unknown if it either killed it or scavenged on an already dead animal)
Episode: Sea Monsters-The Most Dangerous Sea Ever (as 'Giant mosasaur')
Info: One of the largest of the mosasaurs and the apex predator of the Western Interior Seaway of North America, Tylosaurus was the length of a male humpback whale and as evidence in its stomach content shows, it preyed on anything it wanted such as fish, turtles, seabirds, ammonites, giant squid, sharks, plesiosaurs, and even smaller mosasaur species. However, they can sometimes be fiercely territorial with each other as the skull of a Tylosaurus was found bearing bite marks made by another Tylosaurus.

Note: Based on Coloration based on sorta of a Killer Whale's/Orca's as a specimen of Tylosaurus was found revealing its black and white coloration.

The Monstro the Whale of the Western Interior Seaway! Now Let's get out of the sea and fly with a pterosaur before we head back to dry land!
