7 Giant Animals That Are Now Extinct Part 1

4. Giant Ground Sloth

The Elephant-Sized Sloth

Unlike today’s tree-dwelling sloths, ground sloths lived on land and were massive.

Key facts:

• Up to 20 feet tall
• Weighed around 4 tons
• Lived during the Ice Age
• Mostly herbivorous

They lived in grasslands and forests and used caves for shelter. Climate change and early human hunting played a big role in their extinction.
