Zanabazar (dinosaur)
''Zanabazar'' is an extinct genus of troodontid theropod dinosaur from the Late Cretaceous of Mongolia. The genus was originally named by Rinchen Barsbold as a species of ''Saurornithoides'', ''S. junior''. In 2009 it was reclassified as its own genus, named after the first spiritual figurehead of Tibetan buddhism, Zanabazar. The holotype, GIN 100–1, includes a skull, vertebrae, and right hindlimb. ''Zanabazar'' was one of the most derived troodontids, and the second largest after ''Troodon''.
==History of discovery==
In 1974, Rinchen Barsbold described a new specimen of derived theropod from the Bugeen Tsav of the Nemegt Formation, which is dated to about 70 million years ago.〔〔 This specimen, GI No. SPS 100–1, was named by Barsbold as a new species of ''Saurornithoides'', ''S. junior''. The skeleton includes a nearly complete skull and braincase, part of the pelvis, some tail vertebrae, most of the right hindlimb. In 2009 a review of the genus found that the support for ''S. junior'' in the same genus as ''S. mongoliensis'' was lacking. Mark Norell and colleagues re-classified the species in the new genus ''Zanabazar'', which they named in honor of Zanabazar, the first spiritual head (Bogd Gegen) of Tibetan Buddhism in Outer Mongolia.
