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 |

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 |
