E1-02-Extreme Survivors 极限生存

In the Cretaceous Period, plant eaters faced vicious killers.

And none has a worse reputation than Tyrannosaurus Rex, possibly the largest land predator that has ever lived.

T. Rex is sort of the quintessential monster. A dinosaur with an attitude.

A Tyrannosaurus Rex can grow to five 5.5 meters tall and 12 meters long, with jaws designed to tear meat to shreds.

It's reputation for violence and terror is unmatched.

But a infant T. Rex comes into the world better protected than most.

If you say "Tyrannosaurus Rex", I think of gentleness.

I think of superb motherhood and a struggle to raise one's chicks.

The dreaded Tyrannosaurus Rex, it turns out, is one of the most nurturing of all dinosaur parents.

It means taking care of the eggs, sticking around the nest, defending the nest, and keeping track of its progress.
