Genus-level Species-level Clelandina is an extinct genus of rubidgeine gorgonopsian from the Late Permian of Cistecephalus Assemblage Zone of South Africa.
[1][2] Clelandina rubidgei has an extraordinarily small sclerotic ring relative to the size of its orbit, which implies that it was diurnal.
It is the only rubidgeine with a preserved sclerotic ring, so it is unknown whether this trait was shared by other members of the subfamily.
[1] Clelandina shares many characteristics with the contemporary Rubidgea, and is currently recognized as the sister taxon of this genus.
Together with Dinogorgon and Leontosaurus, these genera form Rubidgeini, a clade of large gorgonopsians with distinctively robust, broad, and pachyostosed skulls.
