Glyptodon was a 2.5 m / 8.2 ft. long, stone-age relative of today’s armadillos. The size of a small car, Glyptodon was protected by a rounded, armored shell. Its tail, too, was heavily armored. It belonged to the mammalian group Xenarthra, which contains today’s anteaters, sloths and armadillos.
Glyptodon was herbivorous. Its extinction may have been caused by overhunting by stone-age humans.
