* "C. bestia"
* "C. parvus""Cedaromys" ("Cedar mouse") is an extinct
mammal which lived during the UpperCretaceous , at the same time as manydinosaur s. It was a member of the also extinct order ofMultituberculata . It's within the suborder ofCimolodonta , and a possible member of theParacimexomys group .The genus "Cedaromys" was named by Eaton J.G. and Cifelli R.L. in 2001. As it was first published after their study, Kielan-Jaworowska Z & Hurum JH (2001) didn't comment upon the placement of this genus. It might belong elsewhere.
The species "Cedaromys bestia" was also named by Eaton and Cifelli in 2001. Fossils have been found in Albian (late) - Cenomanian (early), (both Upper Cretaceous)-aged strata of the Cedar Mountain Formation in
Utah (USA ). This is perhaps the fossil formerly known as "Paracimexomys bestia" (Eaton JG & Nelson ME, 1991).Fossils of the species "Cedaromys parvus" (Eaton & Cifelli, 2001) have been found in strata of the same age in the Cedar Mountain Formation. This species is also in the Oklahoma collection. Suggested bodyweight is around 90 g.
