Prehistoric Predators

The dire wolf, a fierce alpha-predator of the Ice Age perishes, while the smaller and weaker grey wolf survives.

The saber-toothed tiger dominates the prehistoric Americas for nearly 2 million years, then becomes extinct.

Standing at 13 feet and weighing over a tonne, this North American native was a predator like no other. Its speed and power made it the most feared carnivore of its time.

Scientists attempt to recreate the Megalodon, a ferocious 50-ton shark that terrorised sea creatures around the world millions of years ago.

Scientists examine the skulls of the terror birds of South America to learn more about their eating and living habits.
