I see a lot of armadillos on the road around here in Georgia.  I didn't know that the name means "little armored one" in Spanish.
What type of animal is an armadillo?
An armadillo is a placental mammal, which means it has a womb, I think.
Where is their habitat range?
Armadillo
Armadillos (from Spanish "little armoured one") are New World placental mammals in the order Cingulata. The Chlamyphoridae and Dasypodidae are the only surviving families in the order, which is part of the superorder Xenarthra, along with the anteaters and sloths. Nine extinct genera and 21 extant species of armadillo have been described, some of which are distinguished by the number of bands on their armour. All species are native to the Americas, where they inhabit a variety of different environments. 
Armadillos are characterized by a
Fruitafossor
Fruitafossor was a termite-eating mammal endemic to North America during the Late Jurassic epoch (around 150 mya).
The description is based on a surprisingly complete skeleton of a chipmunk-sized animal. It was discovered on March 31, 2005, in Fruita, Colorado. It resembled an armadillo (or anteater) and probably ate colonial insects in much the same manner as these animals do today. Other skeletal features clearly show that "Fruitafossor" was not related to armadillos, anteaters, or any modern group
