[Dr. Alice Roberts]
How can we start to come close to animals that lived hundreds of millions of years ago?


Dinosaurs
[Jack Horner]
Dinosaurs

[Bill Nye]
Dinosaurs
Di-Di-Dinosaurs


[Dallas Campbell]
Dinosaurs weren't just giant lizards

But a truly unique kind of reptile

[Narrator 1]

Dinosaurs roamed
For more than 150 million years
Dinosaurs roamed

In amazing shapes and sizes

Very few left evidence of their existence

And those bones never cease to fascinate us

[Roberts]

The more we find
The more complete our understanding
Utterly awe-inspiring

The world of the dinosaurs

[Campbell]

There are always new discoveries out there
Waiting to be found


[Narrator 2]
Tyrannosaurus, the largest flesh eater
The world has ever seen

Dinosaurs - all the dinosaurs-
Followed a well trod trail to oblivion


[Narrator 1]
Rock layers span the age of dinosaurs
The deeper the layer, the older the rock


At the top - rock from the Cretaceous
Below that, the Jurassic

And near the bottom, red Triassic badlands
When dinosaurs first appeared


(refrain)

(dino breakdown)


[Nye]
65 million years ago

[Nigel Marvin]
A meteorite smashed into the Earth
[Nye]

Hurtling toward our planet
At a hundred thousand kilometers a second
**correction: per hour, not second!


[Roberts]
If we'd never found their bones,

We wouldn't ever have known
These ancient animals ever existed


(refrain)
