Asioryctes nemegetensis (Kielan-Jaworowska 1975, 1984) middle Late Cretaceous, Djadokhta Formation, ~85 mya. Asior
Liaoconodonyctes was derived from a sister to Eomaia and phylogenetically preceded Tupaia and the clade Glires (rodents, rabbits, multituberculates) in the large reptile tree. Asioryctes was a late-surviving basal eutherian mammal, presumeably one with a placenta as all living ancestors have one.
Distinct from Eomaia, in Asioryctes the canines were reduced. The retroarticular process of the dentary wrapped around the ectotympanic bones which covered the tiny middle ear bones, the former quadrate, quadratojugal and stapes.
