Glyptodonts first evolved during the Eocene in South America, which remained their center of species diversity.For example, an Early Miocene glyptodont with many primitive features (comparatively to other species), Parapropalaehoplophorus septentrionalis, was discovered at a now-elevated site in Chile and described in 2007.

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.
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.
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.
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.

Boreostemma is an extinct genus of glyptodonts from northern South America. Fossils assigned to the genus were first described as belonging to Asterostemma from southern South America, but have been placed in the new genus Boreostemma by Carlini et al. in 2008.
Palaehoplophorus was identified as an archaic representative of the glyptodonts, notably due to the morphology of its caudal tube, with barely differentiated osteoderms, a characteristic generally considered primitive. The ornamentation of the osteoderms was however rather derived, which tends to confirm that this genus wasn't nested in a basal ...
