Known locations: Mongolia, Bayankhongor Province - Nemegt Formation.
Time period: Late (late Campanian to early Maastrichtian) Cretaceous.
Fossil representation: Initially based upon the description of a partial skull and incomplete post cranial skeleton of single dinosaur, a second partial skeleton has now been described for the genus.
is a genus of dromaeosaurid dinosaur that lived in Asia during the Late
Like with its relatives, Adasaurus
was a hunter of
other animals, quite possibly including other dinosaurs. The
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
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.
