Cimolodonta The Cimolodonta' are extinct mammals that lived from the Cretaceous to the Eocene. They were the more derived members of the extinct order Multituberculata. 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". Cimolodonta is apparently a natural (monophyletic) suborder. Remains have been identified from across the northern hemisphere. Recognized are the informal Paracimexomys group and the superfamilies Djadochtatherioidea, Taeniolabidoidea, Ptilodontoidea. Additionally, (and of uncertain affinities), are the families Cimolomyidae, Boffiidae, Eucosmodontidae, Kogaionidae, Microcosmodontidae and the two genera Uzbekbaatar and Viridomys. More precise placement of these types awaits further discoveries and analysis. References - Kielan-Jaworowska Z. and Hurum J.H. (2001), Phylogeny and Systematics of multituberculate mammals.
