Glyptodon (SciiFii)

Glyptodon (from Greek for "grooved or carved tooth": γλυπτός "sculptured" and ὀδοντ-, ὀδούς "tooth")[4] was a genus of large, heavily armored mammals of the subfamily Glyptodontinae (glyptodonts or glyptodontines) – relatives of armadillos – that lived during the Pleistocene epoch. It was roughly the same size and weight as a Volkswagen Beetle, though flatter in shape. 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.[5][6] 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.[7][8] 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.
