About Panochthus
Panochthus is an extinct genus of glyptodont, which lived in the Gran Chaco-Pampean region of Argentina (Lujan, YupoĂ and Agua Blanca Formations), Brazil (JandaĂra Formation), Bolivia (Tarija and Ă‘uapua Formations), Paraguay and Uruguay (Sopas and Dolores Formations) during the Pleistocene epoch. The first specimen of Panochthus consisted of two carapace (shell) fragments, now lost, recovered from Buenos Aires. In 1845, the fragments were referred by Sir Richard Owen to the genus Glyptodon. In 1864, working from more complete remains, Karl Hermann Konrad Burmeister erected Panochthus as a subgenus. Three years later, he elevated it to the rank of genus. The species named by Owen, now P. tuberculatus, stands as the type species, though many others have since been named.
