Panochthus is an extinct genus of glyptodont, which lived in the Gran Chaco-Pampean region of Argentina (Lujan, Yupoí and Agua Blanca Formations), Brazil (Jandaíra Formation), Bolivia (Tarija and Ñuapua Formations), Paraguay and Uruguay (Sopas and Dolores Formations) during the Pleistocene epoch.^[1]^[2]^[3]^[4]

It could reach 3 metres (9.8 ft) in length and a weight up to 1,500 kilograms (3,300 lb)^[5] the upper skull and the body were protected by hemispherical armor composed of hundreds of rounded scales. The tail, short and wedge-shaped, consisted of small bony bands with small spikes used for defense. Preserved tracheal rings are known from one specimen.^[6]
