Fossil remains of this 2 to 3.5 m long and 35 to 45 kg heavy dinosaur have been found in Mongolia and Tajikistan . The name means "bird-like lizard". The closest relative of the saurornithoid was probably the North American genus Troodon .
With its slim build and oversized second claw, it also resembled a Velociraptor . His eyes were very enlarged, suggesting a nocturnal lifestyle. Saurornithoides could have hunted the small mammals of that time at dusk. Because of many bird characteristics, it is likely that the saurornithoides was covered by a plumage.
