A Nine-Banded Armadillo is one of the mammal species that lived on Earth. They are usally seen in the Northern parts, Western and Southern parts of the planet.
It is not mentioned, but it is presumed that many Nine-Banded Armadillos were brought on board the Arks, in the Zoology chamber, so they can survive from going extinct during the 2012 apocalypse. Other Nine-Banded Armadillos were presumed to be perished in the disastrous results of the apocalypse.
When the apocalypse ended and time was reset to year one, the surviving species of Nine-Banded Armadillos were released into the wild when the continent of Africa had risen above the sea level.
