Narrator in “Death of a Dynasty”

It is the end of the Cretaceous period and the continents are taking on their modern forms. But this ceaseless movement of the Earth's crust has also produced a surge of volcanic activity across the globe.

This desolate world is still ruled by dinosaurs, as it has been for 160 million years, but they are nearing the end of their reign. Life on Earth is choking to death. Yet in the last two million years, the dinosaurs' most infamous predator has appeared: Tyrannosaurus, a five-tonne 13 metre long carnivore, specifically evolved to kill other giant dinosaurs.
