Lyrics:

[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

(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

[Roberts]
If we'd never found their bones,
We wouldn't ever have known
These ancient animals ever existed

(refrain)
