The armadillo (Dasypus novemcinctus) is a rather interesting and unusual animal that has a protective armor of “horny” material on its head, body, and tail. This bony armor has nine movable rings between the shoulder and hip shield. The head is small with a long, narrow, pig-like snout. Canine and incisor teeth are absent. The peg-like cheek teeth range in number from seven to nine on each side of the upper and lower jaw. The long tapering tail is encased in 12 bony rings. The track usually appears to be three-toed and shows sharp claw marks. The armadillo is about the size of an opossum, weighing from 8 to 17 pounds (3.5 to 8 kg).
