Glyptodon (Greek for "grooved or carved tooth") was a large, armored mammal of the subfamily Glyptodontinae (glyptodonts), a relative 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 turtles, and the much earlier dinosaurian ankylosaur, as an example of the convergent evolution of unrelated lineages into similar forms.[1][2] 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.[3][4] For this reason, glyptodonts and all armadillos but Dasypus were relocated to a new family, Chlamyphoridae.
