It belongs to one of the three families of superpredators who know and who have inhabited the Earth: Pliosauridos, Laminidae Carcharodones (the megalodon), and to which it belongs, the Mosasauridae.

The Tylosaurus Mosasaurus species is more bulky and long, with the Hainosaurus, which is closely related. Reached about 50 feet long, and of course, has the essential characteristics of other mosasaurs:
- Adapted to water and reptile related to lizards and snakes today.
- Swimming at high speed because their members had had transformed into flippers and hydrodynamic body shape.
- Huge skull, up to 1.5 meters long ... and very strong high pressure allowing bite.

Certainly, other mosasaurs had a body a bit more robust. But Tylosaurus body allowed him to move with more agility and faster and almost no prey could escape its attack, also to be of a larger size, was fully capable of being the most terrible mosasaur ever.

Might well have reached the 8-ton of muscle. It was definitely one of the few marine superpredators that existed in the Western Interior Seaway during the Late Cretaceous. In fact, the stomach contents of specimens found to indicate that this ferocious Tylosaurus Mosasaurus had a varied diet. A diet that included fish of various sizes, sharks, smaller mosasaurs, plesiosaurs, and diving birds as Hesperornis.


You have certainly heard of Mosasaurus, the great predator of the Cretaceous, a fearsome marine hunter was afraid of other creatures of the sea but ... and Hainosaurus? While not believe it, the Hainosaurus belonged to the same family as the Mosasaurus, Mosasauridae the family.

He was also a marine reptile, an apex predator that lived with her ​​relative Mosasaurus.

Hainosaurus dimensions have been debated: Some experts believe that reached 17 m (57 ft) and 13 m (42 ft) change others, but the vast majority agrees to an average size 15 meters (50ft).

This hunter's skull measuring 1.5 meters (5 ft) long. And in his jaws were more than 60 teeth are sharp and hard. Among their prey were fish, turtles, marine reptiles and even smaller sharks.

The hainosaurus had an elongated body that was perfectly adapted to the water to achieve greater agility and speed. They had fins on the sides and curved tail with fins to swim very fast, to reach out and catch their prey without that it can do almost anything.

This prehistoric animal was specially adapted to be in the water, and some of the questions that have their fossils are related to how and where breeding and giving birth to their young, uncertain whether it was viviparous, oviparous or ovoviviparous.

Although little is known of this marine reptile, I hope you discover more about the wonderful Hainosaurus.


Mosasaurus was among the last mosasaur genera, and among the largest. The skull was more robustly built than other mosasaurs, as the mandibles articulated very tightly with the skull. It had a deep, barrel-shaped body, and with its fairly large eyes, poor binocular vision, and poorly developed olfactory bulbs, experts believe that Mosasaurus lived near the ocean surface, where it preyed on fish, turtles, ammonites, and possibly smaller mosasaurs. The animal remained near the surface and although it was able to dive, it evidentially did not venture into deeper waters.

The skull of Mosasaurus tapered off into a short, conical process, and the jaws were armed with massive, sharp, conical teeth. Their paddle-like limbs had five digits in front and four in back. The trunk terminated in a strong tail which, together with serpentine undulation of the whole body, contributed far more to the animal's locomotion that did the limbs.

Because of its robust skull and tightly articulating jaws, Mosasaurus was unable to swallow prey-items whole in the manner of earlier mosasaurs, such as Tylosaurus[citation needed]. Instead, with the aid of its curved, knife-like teeth, Mosasaurus was able to tear its prey into more manageable pieces that could be more easily swallowed.

Mosasaurus ("lizard of the Meuse River") was a genus of mosasaur, a carnivorous, aquatic lizard, somewhat resembling a flippered crocodile, with elongated heavy jaws. The genus lived in the Maastrichtian age of the Cretaceous period (Mesozoic era), around 70-65 millions years ago in the area of modern Western Europe.

As with most mosasaurs, their legs and feet are modified into hydrofoil-like flippers, with the forelimbs larger than the hindlimbs. Like its American relatives Tylosaurus and Hainosaurus, Mosasaurus reached lengths of about 17 meters.
