Description | Yubaatar is a genus of multituberculate, an extinct order of rodent-like mammals, which lived in what is now China during the Late Cretaceous. The first specimen was discovered in the Qiupa Formation of Luanchuan County, in the Henan Province. The specimen consists of a partial skeleton with a nearly complete skull, and was made the holotype of the new genus and species Yubaartar zhongyuanensis by the Chinese palaeontologist Li Xu and colleagues in 2015. The generic name consists of the word Yu, which is the pinyin spelling of the Chinese character for the Henan Province, and the Mongolian word baatar, which means "hero", a word commonly used as suffix in the names of Asian multituberculates. The specific name comes from Zhongyuan, an ancient name for the geographic area of the province.
