What are Glyptodons?
Glyptodons are ancient ancestors of modern-day armadillos that lived mainly in North and South America over 20,000 years ago. Not much is known about this species, except for it went extinct during the last ice age over 10,000 years ago. From different fossil discoveries and studies, scientists know that these ancient mammals were covered in a protective armor that is very similar to a modern-day turtle.

The protective shell is around two inches thick and five feet long. The glyptodon also had a tail with spikes, which scientists believe was used for protection against predators. While glyptodons were huge (roughly the size of a Volkswagen Beetle), they were gentle giants and only ate plants.
