Glyptodon was one of the biggest ancient armadillos. Fossils of this mammal have been found in Argentina, South America. It was about the size and weight of a small car.

Glyptodon lived in the Ice ages, during the Pleistocene (between 2 million and 10,000 years ago).

Evolutionary history[change | change source]

Humans hunting a glyptodon

Glyptodon is part of the placental group of mammals known as Xenarthra. This order of mammals includes anteaters, tree sloths, extinct ground sloths, extinct pampatheres, and armadillos.

Glyptodon came from South America. A related genus, Glyptotherium, first appeared in the south-west of the modern USA about 2.5 million years ago as a result of the Great American Interchange.

These herbivores (plant-eaters) would not have been vulnerable to the Sparassodont carnivores of the day. The native human population in their range is believed to have hunted them and used the shells for shelter in bad weather.[1][2]
