Walking with Monsters2005

[first lines]

Himself- Narrator:
After millions of years of evolution, our distant ancestors have filled the oceans and crawled out onto land. They have survived the giant insects of the swamps, and mushroomed into massive reptiles armoured to the teeth. But now they've waged so long is now much more than a battle between predator and prey. The whole planet is entering a different kind of crisis. One that will destroy most of these monster reptiles and wipe out 90% of life on Earth.
