MYSTERIES OF THE GIANTS
They came after the dinosaurs
After the extinction of the dinosaurs, the Earth was still populated by other gigantic animals: a 13m long snake weighing as much as a truck, a shark as big as a school bus, a 20-ton rhinoceros and a sloth 200 times the size of current ones.
Although they dominate their ecosystems, giant animals are often more vulnerable than others. They are susceptible to climate change, loss of habitat, shortages of food and competitors invading their territory. In fact, today’s last giants – the descendants of those behemoths – are all in decline. Some of them are even threatened with imminent extinction.
The series looks back on the evolutionary history of 8 giant prehistoric animals.
