The Big Freeze

In a world covered in ice, woolly mammoths and saber-toothed cats fight to survive the coldest temperatures in millions of years.

As sea levels drop and continents shift, animals begin migrating to unknown territories full of new possibilities—and new threats.

With much of the planet's water supply frozen, rock-climbing sloths and marsupial lions must find a way to withstand barren landscapes.

Giant herd animals thrive with the expansion of the grasslands, dominating the plains—but fearsome hunters shadow their every move.

Rising temperatures mean every habitat on the planet is transforming, and for the Goliaths of the Ice Age, the world as they know it is ending.
