Djadochtatherioidea

Djadochtatherioidea is a group of extinct mammals known from the Upper Cretaceous of Central Asia. They were members of an also extinct order called Multituberculata. These were generally small, somewhat rodent-like creatures, who scurried around during 'the age of the dinosaurs'.
Unusually for multituberculates, some of this group are represented by very good remains. All Upper Cretaceous Mongolian multis are included with one exception, Buginbaatar. This superfamily is further subdivided into two families and several other genera, as listed in the table.
For the technically minded, these djadochs are within the suborder of Cimolodonta. Djadochtatherioidea was established by Kielan-Jaworowska and Hurum, 2001, as a replacement for the previously proposed Djadochtatheria Kielan-Jaworowska & Hurum, 1997.
