![]() ![]() The history and taxonomy of Glyptodon is storied and convoluted, as it involved confusion with other genera, dubious species, and lack of detailed data. Georges Cuvier (1769-1832), describer of Megatherium History and taxonomy Confusion with Megatherium 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. 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. ![]() 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. It was roughly the same size and weight as a Volkswagen Beetle, 800–840 kg (1,760–1,850 lb). The holotype used by Owen is a chimera of fossils from 3 different localities, including a molariform used for the name of the genus that actually belongs to Panochthus, making it a species inquirenda. clavipes, was described in 1839 by notable British paleontologist Sir Richard Owen. Hundreds of specimens have been referred to the genus, but the holotype, or name specimen, of the type species, G. Many species have been named for the genus, though few are considered valid, and it is one of, if not the, best known genus of glyptodont. It was the first named extinct cingulate and is the type genus of Glyptodontinae, and, or, Glyptodontinae. Glyptodon (from Greek for "grooved or carved tooth": γλυπτός "sculptured" and ὀδοντ-, ὀδούς "tooth") is a genus of glyptodont (an extinct group of large, herbivorous armadillos) that lived from the Pleistocene, around 2.5 million years ago, to the Early Holocene, around 11,000 years ago, in Argentina, Uruguay, Paraguay, Bolivia, Peru, Brazil, and Colombia. Paraglyptodon uquiensis Castellanos, 1943.
