EPISODE 1
The Dodo
Possibly the most famous extinct animal, the dodo looked very different to modern interpretations.
EPISODE 2
Sabre-Toothed Tiger
One of the most savage and merciless predators to walk the earth, the cause of death of the sabre-toothed tiger is still a mystery.
EPISODE 3
Woolly Mammoth
New research suggests that this ancient giant may not have died with the Ice Age, but rather a human virus may have wiped out the mammoth.
EPISODE 4
Great Auk
Great auks, smaller and lighter than sperm whales, have a hydrodynamic design allowing them to move like torpedoes under water.
EPISODE 5
Irish Elk
The Irish elk, with its 12-foot antlers, suffered at the end of the Ice Age.
EPISODE 6
Tasmanian Tiger
The Tasmanian tiger was an incredible creature that had the head of a wolf, the stripes of a tiger and the body of a dog, and survived for nearly 25 million years.
