Glyptodon

Glpytodon was a large, armored mammal related to the armadillo that lived from the southern US to South America during the Pleistocene epoch between 2.5 million years ago to about 10,000 years ago. It is protected by a round shield on its body that protects it from predators, although it also reduces its speed, making it a slow-moving animal. They mainly thrive within vast grasslands and can sometimes migrate in small herds.
