Adasaurus Dinosaur (Ada Lizard) was a bird-like carnivorous dinosaur that lived 70 million years ago, throughout the late Cretaceous Period. (This name came from the name of a mythological evil demon of Mongolia.)

It has been described as being similar to Archeopteryx and its discovery added fuel to the present debate concerning dinosaurs and birds. Only unfinished fossils have been found, all over Mongolia, but mainly based in the Gobi desert region.

At six feet (two meters) long and two feet (.7 meters) tall, resembling the size of a large dog, Adasaurus weighed only 33 pounds (15 kilograms) and they may had feathers. Like Velociraptor dinosaurs, Adasaurus were bipedal with a big, sickle-like claw on each foot.

Aspects of the Adasaurus dinosaurs pelvis, which was similar to that of ornithischians, lead some scientists to believe that it is more closely connected with birds than dinosaurs.
