The Zanabazar also known as Zanabazar junior is a species of extinct Troodontid theropod dinosaur from the Late Cretaceous of Asia. It lived around 70 to 65 million years ago, and survived until the mass extinction at the end of the Cretaceous. It is the second largest Troodontid after Troodon, and was most likely omnivorous.


Zanabazar was originally discovered in 1974 by Rinchen Barsbold, who named it as a new species of Saurornithoides, S. junior. 

In 2009, Mark Norrel, after research on the fossil, came to the conclusion that Zanabazar was an entirely new genus, and named it Zanabazar, after Zanabazar, the first spritual head (Bogd Gegen) of Tibetan Buddhism in Outer Mongolia.


Zanabazar was, at first, placed within the "Saurornithoididae" (in fact determined to be a synonym for the Troodontidae), however, as of now, it's been placed into the Troodontidae, in the Troodontinae.


Zanabazar is the largest known Asian troodontid, with a skull length of 272 millimetres (10.7 in).

At the time of its discovery, the only other troodontids that appeared to be larger than it were specimens from Alaska currently classified in the genus Troodon.[1]

Latenivenatrix mcmasterae is now considered the largest troodontid. [2]
