Glyptodonts abruptly became extinct approximately 12,000 years ago at the end of the Late Pleistocene, as part of the end-Pleistocene extinction event, along with most other large animals in the Americas. Evidence has been found suggesting that they were hunted by recently arrived Paleoindians, which may have played a role in their extinction. [3]
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.
Dasypus bellus, the beautiful armadillo, [2] is an extinct armadillo species endemic to North America and South America from the Pleistocene, living from 1.8 mya—11,000 years ago, existing for approximately 3]
The smallest species of armadillo, the pink fairy armadillo, weighs around 85 g (3.0 oz) and is 13–15 cm (5.1–5.9 in) in total length. The largest species, the giant armadillo , can weigh up to 54 kg (119 lb), and can be 150 cm (59 in) long.
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.
The name Utaetus is an anagram of Eutatus, another extinct armadillo. In 2021, Claudia Herrera and colleagues named a new species of Utaetus based on several osteoderms that had been unearthed from the Middle Eocene strata of the Upper Lumbrera Formation in Salta Province, Argentina. [2]
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.
†Beautiful armadillo (Dasypus bellus) is an extinct armadillo species found in North and South America about 2.5 million to 11,000 years ago. It is much larger than current-day species at about 2.5 times the size of the normal nine-banded armadillo and had much thicker, more robust armor. [15] [16]
