Adasaurus was a carnivore (meat-eater) that lived in Mongolia during the late Cretaceous period, about 74 to 65 million years ago.
Adasaurus was about 6 to 8 feet (2 to 2.5 meters) long, and probably weighed about 33 pounds (15 kilograms).
Adasaurus was closely related to Dromaeosaurus, and like its relative, was a predator but may also have relied on scavenging. Also like Dromaeosauruswas equipped with a sharp curved claw on each of its hind feet
