The Mosasaurus was a carnivorous aquatic lizard that existed in the Mesozoic era of the Cretaceous period, around 70-66 million years ago in what is now known as western Europe and North America. The first skull fragments were found in 1764 in a chalk quarry in St Pietersberg, Netherlands and in 2012, a skeleton of a Mosasaurus was found in the same quarry. It is thought to be the oldest Mosasaurus skeleton palaeontologists have ever found. The creature appears in Jurassic World as a tourist attraction.

The Mosasaurus had a huge crocodile-style jaw with huge sharp teeth and had large eyes but very poor binocular vision. The creature had four flippers and a strong tail which allowed it to move effortlessly in the ocean. It could grow up to lengths of 59ft. It is believed it lived near the ocean surface feeding on fish, turtles, sharks and other small creatures and never went into deeper waters. Speaking of sharks, it’s also found that some prehistoric species of sharks were able to attack and kill a Mosasaurus.

Jurassic World

In Jurassic World, a Mosasaurus is a tourist attraction at the park – the “Mosasaurus Feeding Show” which is a parody of what SeaWorld does with killer whales. As the audience watches a Great White Shark being dangled above the lagoon, a Mosasaurus bursts out of the water and eats it. The audience can then see it swimming under water. Later in the film, when the Pterosaurs escape and cause havoc, it grabs Zara and inadvertently drops her into the lagoon. As the Pterosaur struggles to grab her from water, the Mosasaurus jumps up and swallows both Zara and the Pterosaur. The Mosasaurus then appears in the climax of Jurassic World. When the Tyrannosaurus and Velociraptor push the Indominus Rex to the lagoon, the Mosasaurus jumps out and grabs the Indominus Rex and drags it under water, killing it.

  1. “Speaking of sharks, it’s also found that some prehistoric species of sharks were able to attack and kill a Mosasaurus.”
    Megalodon comfirmed (not 🙁 )

    1. we technically it depended on the size of the Mosasaurus and probbably type. the type of shark your talking about was a gillit shark.But a tylosaur was probbably one of the the only Mosasaurus to stand up to them

    1. Spinosaurus could kill Indominus rex! Indominus would lunge, but Spinosaurus grabs it on the neck and kills it. DIE INDOMINUS REX

      1. Spinosauru’s bite wouldn’t be powerful enough to kill I-rex.Also,how would spinosaurus react quick enough to grab its neck ? [p.s spinosaurus cant snap necks]

      2. Fool, indominus rex is bigger stronger arms than spinosaurus stronger jaws than tyranniosaurus rex intelligent as a raptor (spino and trex are dumb as compared to i.rex)
        And yes it could survive missilles machine guns and rocket launcher and only being fallen on ground where as spino could not even roll over his back. Irex vs spino is same as a hybrid big cat (irex) vs kitty cat(spino)

        1. Excuse me,maybe he is more intelligent, but there is no way the I-Rex is BIGGER.Compare 18 METERS to 14 meters

      1. Turtle Master, he’s a a spino fanboy (like me) and he simply loves Spinosaurus. I think that is a good hybrid idea by the way. Here’s a name suggestion: Mosaspinus or Spinomosasaurus.

  2. Mr. man is my sneaky super secret identity I just told you about. Ha ha ha, oh wait, uh oh… wup’s

  3. Must now burn my corpse and act like it was an accident…

  4. Spinosaurs sucks it can not defeat the giant carnivor giganotosaurus t-rex albertosaurs and indominous rex spinosaurs is just a dinosaur its not famous like t-REX and INDOMINOUS REX

  5. I don’t have a clue what people post but Indominus is the same size as Spinosaurus. If megaladon were to be in the movie it would make mososaurus look like a chew toy. If anyone has posted so far on how loud Indominus Rex’s roar is. it’s 140-160db the same as a 747 taking off.

  6. Actually, mosasaurus was around 50 feet , and megaladon was around 60 feet, so they were close to the same size

  7. And in mosasaurus feeding show scenes, the mosasaurus actually eat a baby megalodon in whole! Is that crazy!!?

  8. It’s awesome I know the tree just breaks through the fossils in the ending it’s just too cool man (dude)

  9. Have fun with Jurassic World Dominion and i have no clue of what the main killer is going to be maybe Wu is going to re make the indoratper or is going to fuse it with another dino again or it is just going to be the Mosasaurus this time.

  10. The mosasuarus is not going to be the bad guy and the mosasuarus would kill the I rex en spinosuarus

  11. Indoraptor didn’t kill blue bro it was about to but it fell off the roof and landed on a triceratops horns, stabbing it.
