It looked like a giant armadillo, with a tough shell covering its body. This shell helped protect Glyptodon from predators as it roamed South American grasslands and ate plants.

Despite its size—up to 11.5 feet long and weighing over 4,400 pounds—Glyptodon was slow and gentle, using its strong claws to dig for food.

It disappeared around 10,000 years ago, likely due to changes in climate and hunting by early humans.
