Mosasaurs are my favorite extinct creatures. It is one of the greatest aquatic prehistoric creatures ever to rule the seas. The reason I like them is because they look cool and are not dinosaurs. They are distinct from many creatures. Also I watched the mosasaur in "Jurassic World" so its cool and all. Today I will tell you about them. First here are some fast facts about them
Fast Facts
The mosasaur is Not a Dinosaur! It is actually a large aquatic creature if you don't know. There were in the Cretaceous period. They became extinct due to the Mass Extinction Event of the Cretaceous period. The body size of these creatures were 3 to 50 feet. Thats how large they were. Also in the movie the mosasaur is double the size so it isn't real life. The Tylosaur is the largest species of the Mosasaur to exist. Mosasaurs were also very fast. They could twirl around once grabbing their prey to kill. They are related to snakes because of there similar appearances in the jaw. They can move their jaw around to swallow whole prey. They can be found all around the world. In addition they can pretty much eat anything they wanted in the sea.
More Facts
Mosasaurs were reptiles so they always had to go breath up for air once in a while. Mosasaurs were often referred to as the T-Rex of the seas. Mosasaurs and all other marine reptiles died a long time ago luckily for humans, but they rapidly diversity and their was a discovery of a freshwater Mosasaur in Hungary! Their skin is similar to a snake and their jawline. Inside their mouth if you go deeper and then up you can see something that looks like another set of teeth. Both snakes and Mosasaurs have two separate rows of teeth one in the upper.
Tylosaurus
Tylosaurus is probably one of the most well known mosasaurs, due to the fact it's a common centerpiece in many museums, and it's been featured in the Jurassic Park games, comics, and the new movie "Jurassic World". Reaching lengths of over 14 meters (45 feet), it was also one of the larger mosasaurs. Tylosaurus was an apex predator in the Western Interior Seaway of North America during the Cretaceous. This beast could eat just about anything. Smaller mosasaurs and Plesiosaus have been found in the stomach contents of these great marine predators.
This the end of my Mosasaur documentary hope you like it and goodbye.

New research shows they were most likely a dark color, similar to a Sperm Whale coloration.
In the past, the color of prehistoric animals were confined to the realm of artists. Now, paleontologists have found fossilized melanosomes in skin impressions from an ichthyosaurs , ancient turtle, and a mosasaur. The research done by Johan Lindgren (2014), shows these aquatic reptiles were "at least partially dark colored in life." "The mosasaur contained so much of this pigment, it would have been very dark in color, protect against UV radiation when at the surface, and provide camouflage when deep diving."
How did a Mosasaur Swim?
Until recently, the swimming style of a mosasaur could only be determined by the skeleton. Fortunately, in 2011, Johan Lindgren, studied a well preserved fossil mosasaur. This specimen has three preserved muscle fiber bundles. By studying this well preserved specimen, Lindgren suggests the mosasaur held the front of its body rigid and used the rear of its body and tail for propulsion. This makes for a very efficient swimming machine. This is also similar to how crocodiles swim.
