Armadillos have dorsal armor that is formed byosteoderm

A scute or scutum (Latin: ''scutum''; plural: ''scuta'' "shield") is a bony external plate or scale overlaid with horn, as on the shell of a turtle, the skin of crocodilians, and the feet of birds. The term is also used to describe the anterior po ...
s". Most species have rigid shields over the shoulders and hips, with three to nine bands separated by flexible skin covering the back and flanks.
Pampatheres also had shells that were flexible due to three movable lateral bands of osteoderms. The osteoderms of pampatheres were each covered by a single scute, unlike those of armadillos, which have more than one. Glyptodonts, on the other hand, had rigid, turtle-like shells of fused osteoderms.
Both groups have or had a cap of armor atop their heads. Glyptodonts also had heavily armored tails; some, such as '' Doedicurus'', had mace-like clubs at the ends of their tails, similar to those of ankylosaur
