This animal was a member of the extinct order Multituberculata, within the suborder Cimolodonta and family Djadochtatheriidae. The genus ''Tombaatar'' was named by Rougier G.W., Novacek M. and Dashzeveg D. in 1997. The species ''Tombaatar sabuli'' is known from remains found in the Upper Cretaceous Djadokhta Formation of Ukhaa Tolgod, Mongolia. ''Tombaatar'' was a relatively large multituberculate. The skull is about 6 cm in length. ==References== * Rougier, Novacek & Dashzeveg (1997), "A new multituberculate from the late Cretaceous locality Ukhaa Tolgod, Mongolia: Considerations on multituberculate interrelationships", ''American Museum Novitates'' 3191, p.1-26. * Kielan-Jaworowska, Z. & Hurum, J.H.
