Anatomy: Saurornithoides (meaning "lizard bird form") was a theropod dinosaur about 6.5 to 12.5 ft (2 to 3.5 m) long and weighed roughly 28-60 pounds (13-27 kg). It had a bird-like skull and a relatively large brain. The eyes were probably large (the eye sockets were large) and were positioned such that this predator had binocular vision. Some scientists have suggested that the large eyes suggest that this dinosuar was nocturnal (most active at night).

Diet: Saurornithoides was a carnivore, a meat-eater. It was probably a hunter (and not primarily a scavenger), eating small reptiles and mammals.

Fossils: Fossils of this theropod have been found in Mongolia. Saurornithoides was named by paleontologist Osborn in 1924. The type species is S. mongoliensis.
