Djadochtatherioidea is a group of extinct mammals known from the Upper CretaceousThe Cretaceous period is one of the major divisions of the geologic timescale, reaching from the end of the Jurassic period (about 135 mya) to the beginning of the Paleocene epoch of the Tertiary period (65 mya). The end of the Cretaceous also defines the of Central AsiaCentral Asia is a region of Asia. Various definitions of its exact composition exist. Definitions Under one definition, Central Asia covers about 9,029,000 km2, or 21% of the continent. Under this definition Central Asia includes the following countries:.
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 dinosaurSaurischia Ornithischia The dinosaurs were a diverse and long-lived superorder of prehistoric reptiles. What is a dinosaur? Definition Dinosaurs are a superorder of reptiles that first appeared approximately 230 million years ago. A few lines of primitives'.
Unusually for multituberculates, some of this group are represented by very good remains.

It is a member of the extinct order of Multituberculata, the suborder of Cimolodonta, and the family Cimolomyidae. It lived towards the end of the Mesozoic era. Genus: Buginbaatar Kielan.
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.
