Sea Rex 3D: Journey to a Prehistoric World Page #4

The first dinosaur to be named

is Megalosaurus,

which means "great lizard" in Latin.

A well-deserved name

for a 30-foot-long carnivore

with a huge appetite.

Molluscs like ammonites and belemnites

experience an unprecedented growth

and are on the menu

of most marine predators.

By the Late Jurassic,

some animals reach record sizes,

like the Brachiosaurus,

over 1 00 feet long

and can weigh

more than six elephants.

Godzilla. That is the nickname given

to this large marine crocodile

discovered in the Andes.

With large, bony plates on its back,

the Stegosaurus,

a three-ton plant-eater,

is a contemporary

of the very first birds.

At the end of the Jurassic period,

as the continents continue to drift,

new oceans appear and new

Plesiosaur species rule the deep.

The Liopleurodon is most likely

one of the largest ocean predators

of the Mesozoic,

measuring 49 feet or more.

That big?

Here. This is one of its teeth.

It's for you.

Thank you!

You see, the Liopleurodon had

no reason to fear any creature,

save perhaps another Liopleurodon.

Here is a pair of Liopleurodon.

The male is attempting

to court the female.

Look at her - 50 feet of sheer muscle,

four deadly paddle-like limbs,

and jaws about ten feet long

that hold teeth

even bigger than the one l gave you.

During this process,

the male makes himself

extremely vulnerable to the female.

(JULIE) lt seems to have worked.

Now that she's chosen him

as her partner,

the pair needs to head to the safer

coastal waters to reproduce.

Like sharks, the male Liopleurodon

holds on to the female while mating.

Their young will be born

in a few months.

(JULIE) What happened?

It seems that upon separating

she has accidentally injured his eye.

The pain has made him

lose consciousness for a while.

In the end, though,

the Liopleurodon remains

a superpredator that lives alone.

At the end of the Jurassic Era,

its territory spanned

from Europe to South America.

Here we are with Zulma Gasparini,

who discovered the marine crocodile

nicknamed "Godzilla" in the Andes.

People believed for a long time

that the world had always

been the same as it is now.

And it was only in 1 91 5 that Alfred

Wegener, a young German scientist,

put forward a revolutionary theory

he called the "continental drift".

Among the solid arguments that

Wegener used to support his theory,

a tiny marine reptile

that lived 250 million years ago,

the Mesosaurus, was to become

unexpectedly important.

Indeed we have found on both sides

of the Atlantic Ocean

identical fossils of this animal.

But considering the small size

of the Mesosaurus,

like the one we have here
