Sinobaatar
Sinobaatar is a genus of extinct mammal from the Lower Cretaceous of China. It is categorized within the also extinct order Multituberculata and among these it belongs to the plagiaulacid lineage (a possible infraorder). "Sinobaatar" was a small herbivore during the Mesozoic era, commonly called "the age of the dinosaurs". The genus was named by Hu Y. and Wang Y. in 2002. Three species have been described. It has been found in Lower Cretaceous strata of the Yixian Formation in Liaoning, China. According to Hu & Wang (2002), "[t]he dental features of "Sinobaatar" show again that eobaatarids are obviously intermediate  between Late Jurassic multituberculates and the later forms". Many Multituberculata are only known from teeth, but the type specimen of "Sinobaatar" is a reasonably complete skeleton. "Sinobaatar" was eaten, at least on occasion, by the feathered dinosaur "Sinosauropteryx prima" (Hurum "et al." 2006). Etymology. The name "Sinobaatar" is a Latin and Mongolian mixture of "Sino–" and "Bataar" (Baghatur) and means "Chinese hero". The type species name is in honor of Lingyuan City.
