[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

At the top - rock from the Cretaceous Below that, the Jurassic And near the bottom, red Triassic badlands When dinosaurs first appeared
