Essonodon is a
extinct order Multituberculata and lived towards the end of the "age of the dinosaurs." It is within the suborder Cimolodonta and perhaps the family Cimolomyidae
.
The genus Essonodon was named by Simpson G.G. in 1927, and is also partly known as Cimolodon. The inclusion of this taxon within Cimolomyidae is tentative. (Kielan-Jaworowska & Hurum 2001, p. 408).
The species: Essonodon browni has also partly been known as Cimolodon nitidus (Marsh 1889).
Place: Hell Creek, Montana & San Juan Basin, New Mexico & Wyoming (USA)
Age: Maastrichtian (Upper Cretaceous)
This species was a large multituberculate that weighed in at over 2.5 kilograms. Further material has been reported from the Frenchman Formation of Canada.
