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.
In 2016, an analysis of the mitochondrial genome of Doedicurus found that it was, in fact, nested within the modern armadillos as the sister group of a clade consisting of Chlamyphorinae (fairy armadillos) and Tolypeutinae (giant, three-banded and naked-tailed armadillos).
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.
Brown also recombined Glyptodon mexicanum into Brachyostracon mexicanum. [13] Brachyostracon is now seen synonymous with Glyptotherium on the genus level, but G. cylindricum is a valid species. [2] [14] In 1923, Oliver Perry Hay named a new species of Glyptodon, G. rivipacis, based on the fossils described by Leidy from DeSoto County, Florida. [15]
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.
Along with three perforated giant sloth bones found in Brazil that archaeologists believe humans used as pendants 25,000 to 27,000 years ago, the butchered armadillo bones suggest that humans were ...
The largest species, appropriately called the giant armadillo, averages five feet long and 60 pounds ― however, one captive specimen has been measured at 180 pounds.
The giant armadillo is the largest living species of armadillo, with 11 to 13 hinged bands protecting the body and a further three or four on the neck. [6] Its body is dark brown in color, with a lighter, yellowish band running along the sides, and a pale, yellow-white head.
