Glyptodon

Glyptodon is an extinct genus of large, armored glyptodont mammals from Pleistocene South America. Its massive domed shell was made of fused bony plates.

Glyptodontinae: A subfamily of extinct glyptodonts, the heavily armored relatives of armadillos. Glyptodon belongs to this group of large-bodied, heavily armored mammals.
Glyptodon clavipes: A species of Glyptodon known from Pleistocene South American fossils. Its remains are among the best-known examples used to study the genus.
Doedicurus: An extinct South American glyptodont genus with a long, spiked tail club. Its weaponized tail contrasts with Glyptodon's less elaborate tail.
Pleistocene megafauna: Large animal species that lived during the Pleistocene epoch. Glyptodon was one of South America's conspicuous giant mammals of this period.
Xenarthra: A mammal superorder that includes armadillos, anteaters, and sloths. Glyptodon was a xenarthran, despite its striking differences from living members.
Glyptodon reticulatus: A species of Glyptodon with a distinctive pattern of grooves on its shell plates. Its shell ornamentation illustrates variation among recognized Glyptodon species.
Panochthus: An extinct genus of large South American glyptodonts with armored tails. Its tail armor offers a clear comparison with Glyptodon's body-dominated protection.
Quaternary extinction event: The widespread loss of large animal species near the end of the Pleistocene and into the Holocene. Glyptodon disappeared during the broader late-Pleistocene megafaunal extinctions.
Osteoderm: A bony plate or scale formed within the skin of an animal. Its shell consisted of many fused osteoderms rather than a single bone.
Pampas: A broad South American grassland region spanning parts of Argentina, Uruguay, and Brazil. Pampas fossil deposits preserve important remains of Glyptodon and other megafauna.
