Acratophorus is an extinct genus of dicynodont that lived during the Anisian age of the Middle Triassic-aged Río Seco de la Quebrada Formation in what is now Argentina.[1] The type species, A. argentinensis, was originally placed in the genus Kannemeyeria by Jose Bonaparte in 1966,[2][3] and later sometimes referred to Vinceria,[4] before being transferred to a new, distinct genus, Acratophorus, in 2021 by Christian Kammerer and Angi Ordoñez.[5] The species Vinceria vieja was also made a synonym of A. argentinensis in 2021.[6] The holotype is PVL 3645, a partial skeleton discovered near a farm house in Puesto Viejo.[1][5]
