In Depth

       Adasaurus is a genus of dromaeosaurid dinosaur that lived in Asia during the Late Cretaceous.‭ ‬Like with its relatives,‭ ‬Adasaurus was a hunter of other animals,‭ ‬quite possibly including other dinosaurs.‭ ‬The primary killing weapons for Adasaurus would have been the two enlarged sickle claws on its feet,‭ ‬which may have been used to jab at prey.‭ However, while enlarged, the sickle claws of Adasaurus seem to have been smaller than those of some relative dinosaur genera. ‬Although not confirmed,‭ ‬because Adasaurus is a dromaeosaurid dinosaur,‭ ‬it is expected to have had at‭ ‬least some feathers present on the body in life.

       Adasaurus was named after an evil spirit called Ada which appears in Mongolian mythology.‭ ‬The species name mongoliensis simply means‭ ‘‬From Mongolia‭’‬.‭ ‬Adasaurus is one of many dinosaurs recovered from the world famous Nemegt Formation,‭ ‬which also holds other notable dinosaur genera such as Alioramus,‭ ‬Gallimimus,‭ ‬Avimimus,‭ ‬Therizinosaurus and Tarbosaurus amongst an ever increasing number of discovered dinosaurs.
