Name: Glyptodon ‭(‬Carved tooth‭)‬.

Phonetic: Glip-toe-don.
Named By: Richard Owen‭ ‬-‭ ‬1839.
Diet: Herbivore.
Size: Around‭ ‬2.5‭ ‬to‭ ‬3.3‭ ‬metres long.
Known locations: Across South America as well as Mexico and the USA‭ ‬-‭ ‬Arizona,‭ ‬Florida,‭ ‬New Mexico,‭ ‬Oklahoma and Texas. Time period: Late Pliocene until he very end of the Pleistocene,‭ ‬possibly very early Holocene. Fossil representation: Remains of over at least‭ ‬150‭ ‬individ
uals.
Glyptodon had a stubby tail with a rounded end,‭ ‬although as an exposed extremity,‭ ‬it was likely covered with scutes of its own for defence.‭ ‬The presence of Glyptodon in North America as well as South America is proof that this genus took part in the Great American Interchange.
Glyptodon acquired its name‭ (‬which means carved tooth‭) ‬from the form of the molar teeth at the back of the mouth,‭ ‬which were also the only teeth present.‭ ‬Glyptodon instead relied upon shearing and pulling plants with the front of its mouth before moving the mouthful back to the rear teeth for processing.‭ ‬Like its relatives,‭ ‬Glyptodon also had a covering of bony armoured scutes that combined to form a protective shell around the body which would have provided quite substantial protection from the teeth of predators that may not have even been able to close their jaws around the shell properly due to the shells immense size.
Glyptodon seems to have gone extinct around eleven thousand years ago,‭ ‬which coincidentally is not long after the very first humans arrived in South America.‭ ‬While the armour of Glyptodon would have provided a powerful blanket defence against most predators,‭ ‬human hunters could use their intelligence to identify weak and vulnerable areas of the body and then use specially crafted tools to strike at them.‭ ‬This hunting is considered to be the most likely cause of the extinction of Glyptodon,‭ ‬though the human hunters of old were anything but wasteful.‭ ‬Aside from eating the meat of the body,‭ ‬the armoured shells of Glyptodon also seem to have been used as shelters by early human settlers.
