Zanabazar is a genus of troodontid dinosaur from the Late Cretaceous Period of Mongolia. Fossils from this creature have been found in the Nemegt Formation in Mongolia.
Zanabazar was originally classified as a new species of the genus Saurornithoides by Rinchen Barsbold in 1974. A 2009 review of the genus found that there was little proof to back up this idea. The species was re-classified to its current genus Zanabazar — named in honor of Zanabazar, the first spiritual head of Tibetan Buddhism in Outer Mongolia.
Zanabazar is the largest known Asian troodontid. Its skull length is 10.7 inches. It is much larger than all other known troodontids, except for Troodon.
