Smilesaurus is an extinct genus of gorgonopsian known from South Africa. It lived during the Late Permian. It contains the single species S. ferox. [1]
Smilesaurus was a large gorgonopsian, with a skull length of up to 31 centimeters. It is characterized by extremely long canine teeth, and has the proportionally longest canines of any gorgonopsian. [2] [1] Unlike other gorgonopsians, which probably hunted similarly to predatory reptiles, Smilesaurus probably was a true saber-toothed predator which hunted using similar tactics to saber-toothed cats. [1] It can be distinguished by other rubidgeines by its lack of cranial pachyostosis and rugosoties, and by its relatively small orbits. [1]
The classification of Smilesaurus has been disputed. It has often been included in Rubidgeinae, but it differs from other members of the clade considerably. [1] Instead, it may be more closely related to Arctops, [3] a position supported by a phylogenetic analysis in 2018. [4]
