       Cyonosaurus is a genus of gorgonopsid that lived in South Africa during the late Permian.‭ ‬As a gorgnopsid,‭ ‬Cyonosaurus would have been a predator of other animals,‭ ‬smaller to equal in size in its self.‭ ‬Smaller species of Cyonosaurus with skulls about nine centimetres long grew to about sixty centimetres in length,‭ ‬while larger species with skulls about eighteen centimetres long reached lengths of just over a meter.
