Glyptotherium (from Greek for 'grooved or carved beast') is a genus of glyptodont (an extinct group of large, herbivorous armadillos) in the family Chlamyphoridae (a family of South American armadillos) that lived from the Early Pliocene, about 3.6 million years ago, to the Late Pleistocene, around 15,000 years ago.
Doedicurus (Ancient Greek δοῖδυξ "pestle" and oυρά "tail") is an extinct genus of glyptodont from South America containing one species, D. clavicaudatus.Glyptodonts are a member of the family Chlamyphoridae, which also includes some modern armadillo species, and they are classified in the superorder Xenarthra alongside sloths and anteaters.
Glyptodon (lit. ' grooved or carved tooth '; from Ancient Greek γλυπτός (gluptós) 'sculptured' and ὀδοντ-, ὀδούς (odont-, odoús) 'tooth') [1] is a genus of glyptodont, an extinct group of large, herbivorous armadillos, that lived from the Pliocene, around 3.2 million years ago, [2] to the early Holocene, around 11,000 years ago, in South America.
The first is the traditional Glyptodontinae, which is includes the well known genera of Glyptodon and Glyptotherium, which probably originated in Northern South America, while the second is the unnamed "Austral clade", containing the majority of glyptodont diversity, which as the name suggests probably originated in Southern South America.

Parapropalaehoplophorus septentrionalis was a comparatively small (compared to Glyptodon) species of glyptodont, extinct relatives of the modern armadillo.The mammal, identified in 2007 from the fossilized remains of a specimen found in 2004, weighed approximately 200 pounds and had a shell covered by tiny circular bumps.

Holmesina is an extinct genus of pampathere, an extinct group of armadillo-like xenarthrans that were distantly related to extant armadillos. Like armadillos, and unlike the other extinct branch of megafaunal cingulates, the glyptodonts, the shell was made up of flexible plates which allowed the animal to move more easily.
Macroeuphractus is a genus of extinct armadillos from the Late Miocene to Late Pliocene of South America.The genus is noted for its large size, with Macroeuphractus outesi being the largest non-pampathere or glyptodont armadillo discovered, as well as its specializations for carnivory, unique among all xenarthrans.
This animal, like all glyptodonts, had a dorsal armor protecting a large part of the body, consisting of well-fused polygonal osteoderms.The osteoderms were quite similar to those of Palaeohoplophorus, with a medium-sized, depressed central figure, and with wrinkled and irregular peripheral areas.
