The Triassic dicynodont Vinceria (Therapsida, Anomodontia) from Argentina and a discussion on basal Kannemeyeriiformes

In 1969, Bonaparte described a new dicynodont, Vinceria andina, from the early Middle Triassic Cerro de las Cabras Formation of central-western Argentina (Potrerillos, Mendoza). Later, this author mentioned two additional specimens from the same beds, but they were never figured and/or described unt...
