Cimolodonta is a clade of multituberculate mammals that lived from the Cretaceous to the Eocene . They probably lived something of a rodent -like existence until their ecological niche was assumed by true rodents. The more basal multituberculates are found in a different suborder, "Plagiaulacida ", a paraphyletic group containing all non cimolodontan multituberculates.
Cimolodonta is apparently a natural (monophyletic) suborder. Remains have been identified from across the Northern Hemisphere . They first appeared during the Aptian , and completely replaced the more primitive plagiaulacidans by the early Late Cretaceous.[2 ] Paracimexomys group and the superfamilies Djadochtatherioidea , Taeniolabidoidea , and Ptilodontoidea . Additionally, and of uncertain affinities, are the families Cimolomyidae , Boffiidae , Eucosmodontidae , Kogaionidae , Microcosmodontidae and the two genera Uzbekbaatar Viridomys
