==Description== thumb|left|Skull of Smilesaurus ferox 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. 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. It can be distinguished by other rubidgeines by its lack of cranial pachyostosis and rugosoties, and by its relatively small orbits.
