Bunostegos
 Bunostegos (knobbly [skull] roof) is an extinct genus of pareiasaur parareptile from the Late Permian of the Agadez Region in Niger. The type species Bunostegos akokanensis was named from the Moradi Formation in 2003. It was a cow-sized animal with a distinctive skull that had large bony knobs similar in form to those of other pareiasaurs but far larger. The species appears to have lived in a desert in the centre of the supercontinent of Pangaea.
