Like its cousin "Troodon", "Saurornithoides" was an intelligent predator, with large eyes and good vision. It had a retractable, sickle-shaped claw on the second claw of each foot that was used for attacking prey. "Saurornithoides" probably fed on small prey, such as lizards, frogs, insects, and small mammals. It may also have hunted in packs to bring down other dinosaurs. "Saurornithoides" was discovered in the Gobi Desert on an expedition in the 1920s. The dinosaurs "Velociraptor", "Protoceratops", and "Oviraptor" were also discovered during these expeditions to the Gobi Desert.
