Glyptotherium is a genus of glyptodont that lived from the Early Pliocene, about 1.8 million years ago, to the Early Holocene, around 7,000 years ago, in the United States, Mexico, Guatemala, Costa Rica, Honduras, El Salvador, Panama, Venezuela, and Brazil. Many specimens have been assigned to the genus, but the holotype, or name specimen, of the type species, G.texanum, was described in 1903 by notable American paleontologist Henry Fairfield Osborn. The holotype included a nearly complete carapace, tail, or caudal, armor, and several additional postcranial elements that had been found in the Pliocene Blancan Beds in Llano Estacado, Texas, USA. The genus has since been discovered from many more fossil sites and another species, G. cylindricum, was named in 1912 by fossil hunter Barnum Brown on the basis of a partial carapace, teeth, and several additional fossils that had been unearthed from the Pleistocene deposits in Jalisco, Mexico.
Hoplophorus was an extinct genus of glyptodont, a subfamily of armadillos. The only confidently known species was H. euphractus, found in Pleistocene deposits in Brazil, though fossils possibly from another species are known from Bolivia.
Glyptodon is a genus of glyptodont that lived from the Pleistocene, around 2.5 million years ago, to the Early Holocene, around 11,000 years ago, in Argentina, Uruguay, Paraguay, Bolivia, Peru, Brazil, and Colombia. It was the first named extinct cingulate and is the type genus of Glyptodontinae, and, or, Glyptodontinae. Many species have been named for the genus, though few are considered valid, and it is one of, if not the, best known genus of glyptodont. Hundreds of specimens have been referred to the genus, but the holotype, or name specimen, of the type species, G. clavipes, was described in 1839 by notable British paleontologist Sir Richard Owen. It was roughly the same size and weight as a Volkswagen Beetle, 800–840 kg (1,760–1,850 lb). With its rounded, bony shell and squat limbs, it superficially resembled a turtle, and the much earlier dinosaurian ankylosaur – providing an example of the convergent evolution of unrelated lineages into similar forms. In 2016 an analysis of Doedicurus mtDNA found it was, in fact, nested within the modern armadillos as the sister group of a clade consisting of Chlamyphorinae and Tolypeutinae. For this reason, glyptodonts and all armadillos but Dasypus were relocated to a new family, Chlamyphoridae, and glyptodonts were demoted from the former family Glyptodontidae to a subfamily.
Propalaehoplophorus, also written as Propalaeohoplophorus, is an extinct genus of glyptodont, which lived in South America during the Early Miocene epoch.
Stegotherium is an extinct genus of long-nosed armadillo, belonging to the Dasypodidae family alongside the nine-banded armadillo. It is currently the only genus recognized as a member of the tribe Stegotheriini. It lived during the Early Miocene of Patagonia and was found in Colhuehuapian rocks from the Sarmiento Formation, Santacrucian rocks from the Santa Cruz Formation, and potentially also in Colloncuran rocks from the Middle Miocene Collón Curá Formation. Its strange, almost toothless and elongated skull indicates a specialization for myrmecophagy, the eating of ants, unique among the order Cingulata, which includes pampatheres, glyptodonts and all the extant species of armadillos.
Neosclerocalyptus was an extinct genus of glyptodont that lived during the Pliocene, Pleistocene, and Holocene of Southern South America, mostly Argentina. It was small compared to many Glyptodonts at only around 2 meters long and 360 kilograms.
Kelenkura is an extinct genus of heavily armored mammals belonging to the subfamily Glyptodontinae, from the family Chlamyphoridae that contain most of the modern armadillos. It was a medium-sized South American animal, distantly related to Doedicurus. Fossils of this genus were recovered in the Arroyo Chasicó Formation and in the Loma de Las Tapias Formation of Argentina in rocks dating back to the Late Miocene epoch.
Proeuphractus is an extinct genus of xenarthran, related to the modern armadillos. It lived from the Early to the Late Miocene, and its fossilized remains were discovered in South America.
Glyptatelus is an extinct genus of Glyptodont. It lived from the Late Eocene to the Middle Oligocene, and its fossilized remains are found in South America.
Protoglyptodon is an extinct genus of Glyptodont. It lived during the Late Miocene, and its fossilized remains were found in South America.
